features:
* Some cosmetic adjustments of the API, like using references instead of
pointers, argument order, method names, etc.
* Added convenience template methods for archiving and unarchiving to BArchiver
and BUnarchiver.
* BUnarchiver (respectively the private BUnarchiveManager) explicitly deals with
object ownership, now. This is necessary since an error while unarchiving
could leave an already unarchived object without owning object, which would
result in it being leaked. The BUnarchiver::{Get,Find}Object() methods do now
have an optional parameter to specify whether object ownership shall be
transferred.
* Fixed incorrect header guard in headers/private/binary_compatibility/Global.h.

* updated icu-devel package to 4.4.1
* create appropriate devel lib links when icu-devel is being installed
(which only works during build, not when using installoptionalpackage)
* dropped ICU headers from repository and instead fetch them from the
icu-devel package when needed during the build
* adjusted Jamfiles that make use of ICU-headers accordingly (hopefully
I didn't miss any)

vm_page::Init().
* Made vm_page::wired_count private and added accessor methods.
* Added VMCache::fWiredPagesCount (the number of wired pages the cache
contains) and accessor methods.
* Made more use of vm_page::IsMapped().
* vm_copy_on_write_area(): Added vm_page_reservation* parameter that can be
used to request a special handling for wired pages. If given the wired pages
are replaced by copies and the original pages are moved to the upper cache.
* vm_copy_area():
- We don't need to do any wired ranges handling, if the source area is a
B_SHARED_AREA, since we don't touch the area's mappings in this case.
- We no longer wait for wired ranges of the concerned areas to disappear.
Instead we use the new vm_copy_on_write_area() feature and just let it
copy the wired pages. This fixes#6288, an issue introduced with the use
of user mutexes in libroot: When executing multiple concurrent fork()s all
but the first one would wait on the fork mutex, which (being a user mutex)
would wire a page that the vm_copy_area() of the first fork() would wait
for.

* Applications don't have to declare BCatalog fCatalog themselves, it's now done automatically
* Libs and add-ons can be localized just the same way (except static libraries)
For now this new system is yet disabled as I'm looking for some peer review before going on. To enable it you have to define B_TRANSLATE_USE_NEW_MACROS in each file doing catalog access. This will not stay, I'll update the
other apps to use it.
The linking in jamfiles must be not only with liblocale.so, but also liblocalestub.a. Not sure how to handle this for user-side applications. Libraries are also required to provide a MIME signature to use any catalog.
The locale preflet is updated to the new system (as a test). Othe rapps will follow if everyone is ok with this approach.

map_physical_memory()'s physicalAddress parameter type from void* to

- Added macro __HAIKU_ARCH_BITS specifying the architecture bitness (32/64)
(might be more convenient to use than __HAIKU_ARCH_{32,64}_BIT).
- Added macros __HAIKU_ARCH_PHYSICAL_BITS, __HAIKU_ARCH_PHYSICAL_{32,64}_BIT,
and the types __haiku_phys_[s]addr_t. The intention is to use separate
macros and types for virtual and physical addresses, since for some
architectures (e.g. x86 with PAE) those actually differ.
* sys/types.h, BeBuild.h, SupportDefs.h:
- Added types phys_[s]addr_t and respective printf() format macros.
- Added public macros B_HAIKU_BITS, B_HAIKU_PHYSICAL_BITS,
B_HAIKU_PHYSICAL_{32,64}_BIT.

and looks more like the rest of the API.
* Also, it will now return an appropriate error code if the language couldn't
be allocated (anything else than B_OK is an improvement :-)).
* Several changes in BLanguage:
- GetName() now gets a BString reference, also
- it now returns the name in its own language, ie. for German this would
always be "deutsch", no matter the current language settings, and finally,
- it now empties the string it gets before adding the name.
- added GetTranslatedName() that behaves like the previous version.
- added const where it made sense (ie. almost everywhere).
- Code() now returns the code of the language only.
- ID() now returns the full ID of this language, ie. including country,
variant, and keywords if any.
- added Country(), and Variant().
- renamed IsCountry() to IsCountrySpecific().
- added IsVariant().
* Cleaned up Language.h, minor cleanup in LocaleRoster.cpp.
* Removed the whole move item logic from LanguageListView; while this was not
only spaghetti code, it doesn't make much sense in the first place.
* Instead of removing stuff from the left, and even worse, moving all countries
for a language even if only one had been dragged, we now only mark the items
that are already in the preferred list, and only those.
* Fixed various mixups of FullList*() vs. *() methods that could lead to things
like bug #5896.
* Pressing the delete key in the preferred list view will now remove the
language.
* Moved LocaleWindow specific message constants to LocaleWindow.cpp; Locale.h
is supposed to contain application wide constants.
* The drop logic is now in LocaleWindow.
* We now make sure that each base language can only be in the list once.
* Lots of cleanup, even though I mostly replaced spaghettie code with different
looking spaghettie code - still, I think things have slightly improved.

map_backing_store() doesn't commit memory when this flag is given.
* Used the new flag vm_copy_area(): We no longer commit memory for read-only
areas. This prevents read-only mapped files from suddenly requiring memory
after fork(). Might improve the situation on machines with very little RAM
a bit.
We should probably mark writable copies over-committing, since the usual
case is fork() + exec() where the child normally doesn't need more than a
few pages until calling exec(). That would significantly reduce the memory
requirement for jamming the Haiku tree.

B_USER_AREA_FLAGS, since we really allow it to be passed from userland.
* Most VM syscalls check the provided protection against B_USER_AREA_FLAGS
instead of B_USER_PROTECTION, now. This way they allow for
B_OVERCOMMITTING_AREA as well.

smp_cpu_rendezvous(). It's very unlikely on real hardware that the non-boot
CPUs are so much slower, but it might be a concern in emulation.

component of a 32 bit color is below 128 and returns the special CMAP8 index
for indicating transparency.
* Changed the WriteCMAP() color conversion function to expext a 32bit RGBA
value and use IndexForRGBA32().
* Adapted B_CMAP8 target color space case of ConvertBits() to the new
semantics.
This allows transparency in bitmaps when converting B_RGBA32 bitmaps to
B_CMAP8, tested only for this case and working as expected.

free respective free and cached pages.
* Removed the unused vm_page_allocate_page_run_no_base().
* vm_page_allocate_page_run() (and allocate_page_run()):
- Use vm_page_reserve_pages() instead of vm_page_try_reserve_pages(), i.e.
wait until the reservation succeeds.
- Now we iterates two times through the pages to find a suitable page run. In
the first iteration it only looks for free/clear pages, in the second
iteration it also considers cached pages. This increases the chance of the
function to succeed, when a lot of caching is going on.
This reduces the amount of memory required to use the IOCache when booting
off the anyboot Live CD to around 160 MB in qemu. It also seems to work with
128 MB, but the syslog indicates that some memory allocations fail, which
is not exactly inspiring confidence.

* Disable old embedded controller and remove it from image.
* Move embedded controller code to busmanager module.

- Reimplemented mutex to use the _kern_mutex*() syscalls.
- The initializer functions cannot fail anymore -- changed their return type
to void.
- Changed the initializer function semantics to not copy the name by default
anymore (as in the kernel). Also added *_etc() versions of them that take an
additional flags.
- Added static initializer macros.
- Made the mutex (and thus recursive_lock) lock functions non-interruptable.
- Got rid of the "lazy" version. They are no longer needed, since the
initialization of the standard types can be done statically and cannot fail.
* Adjusted libroot, runtime loader, and other code using the private libroot
locking primitives to the new semantics.
* pthreads mutexes and condition variables:
- Reimplemented using the _kern_mutex*() syscalls.
- Consistently use POSIX error codes.
- Fixed some not quite POSIX compliant behavior.

* Exposed ACPI API needed by Embedded Controller
This will be removed again if moved inside the bus manager.
It also duplicates ACPI's own headers so it might go out of sync atm.
* Added mutex to controller and fixed the mixup between acpi_status needed in int handlers and Haiku status.
* Major code cleanup
Not for headers as they are mostly redundant if we move the controller.
Variable names still needs some cleanup
This makes the ACPI errors from the controller understandable. I get AE_NO_HARDWARE_RESPONSE now.

- Added "team" parameter for specifying the address space the address are
to be interpreted in.
- When the standard memcpy() (with fault handler) fails, fall back to
vm_debug_copy_page_memory().
* Added debug_is_debugged_team(): Predicate returning true, if the supplied
team_id refers to the same team debug_get_debugged_thread() belongs to.
* Added DebuggedThreadSetter class for scope-based debug_set_debugged_thread().
Made use of it in several debugger functions.
* print_demangled_call() (x86): Fixed unsafe memory access.

* Add the remaining IDT entries and redirection functions in the interrupt code.
* Make the PIC end_of_interrupt() return a result to indicate whether the vector
was handled by this PIC. If it isn't we now issue a apic_end_of_interrupt()
in the assumption of apic local interrupt, MSI or IPI. This also removes
the need for the gUsingIOAPIC global and doing manual apic_end_of_interrupt()

BBufferConsumer::BufferReceived() cannot know whom to send the "buffer is
late" notification (unless we only have a single input). To solve this, the
media_header now contains extra fields that can be used to create a
media_source object.
* Unfortunately, BBufferProducer::SendBuffer() cannot know the output either in
case there is more than one. Hence, I deprecated the existing SendBuffer()
call and moved it into "private" - IOW old sources using it won't compile
anymore under Haiku.
* I introduced a new SendBuffer() variant that also gets the media_source as
argument.
* Updated all sources (that are part of the image) to use the new variant.
* Removed some purposely commented out code in the audio mixer.
* Implemented late buffer notification, as well as late buffer handling in the
audio mixer; this is a bit of work in progress, so the debug output is left
in there.
* Some cleanup.

locks.
* Added syscalls for a new kind of mutex. A mutex consists only of an int32 and
doesn't require any kernel resources. So it's initialization cannot fail
(it consists only of setting the mutex value to 0). An uncontended lock or
unlock operation can basically consist of an atomic_*() in userland. The
syscalls (when the mutex is contended) are a bit more expensive than semaphore
operations, though.

syscall restart even when a signal handler without SA_RESTART was invoked.
* Fixed sigwait(): If one of requested signals wasn't already pending it would
never wake up. Also, the syscall always needs to be restarted, if interrupted
by another signal.
* Renamed a bunch of the POSIX signal function implementations which did return
an error code directly (instead via errno). Added correct POSIX functions
where needed.

Since the requirement is that the area's top cache is locked, allocating

* _user_map_file(), _user_unmap_memory(): Verify that the address (if given) is
page aligned.
* Reworked memory locking (wiring):
- VMArea does now have a list of wired memory ranges and supports waiting for
a range to be removed.
- vm_soft_fault():
- Added "wirePage" parameter that, if given, makes the function wire the
page and return it.
- Added "wiredRange" parameter (for calls from lock_memory_etc()) and made
sure we never unmap wired pages. This could e.g. happen when a page from a
lower cache was read-mapped and a write fault occurred. Now in such a
situation the function waits for the page to be unwired and restarts.
- All functions that manipulate areas in a way that could affect wired ranges
do now either require the caller to make sure there are no wired ranges in
the way or do that themselves. Added a few wait_if_*_is_wired() helper
functions for that purpose.
- lock_memory_etc():
- Does now also work correctly when the range spans more than one area.
- Adds VMAreaWiredRanges to the affected VMAreas and retains an address
space reference (so that the address space won't be deleted as long as a
wired range exists).
- Resolved TODO: The area's caches are now locked when
increment_page_wired_count() is called.
- Resolved TODO: The race condition due to missing locking after looking up
the page mapping is now prevented. We hold the cache locks (in case the
page is already mapped) and the new vm_soft_fault() parameter allows us
to get the page wired.
- unlock_memory_etc(): Changes symmetrical to those in lock_memory_etc() and
resolved all TODOs.

Added fields for temporary storage of the debug registers dr6 and dr7 to the
arch_cpu_info structure. The actual registers are stored at the beginning of
x86_exit_user_debug_at_kernel_entry() and read in
x86_handle_debug_exception().
The problem was that x86_exit_user_debug_at_kernel_entry() itself overwrote
dr7 and, if kernel breakpoints were enabled, dr6 could be overwritten anytime
after. So x86_handle_debug_exception() would find incorrect values in the
registers (definitely in dr7) and thus interpret the detected debug condition
incorrectly. Usually watchpoints were recognized as breakpoints.

* Added BShape::ArcTo() and BShapeIterator::IterateArcTo(), using a previously
unused virtual slot. (Added the symbols for binary compatibility for GCC2
and GCC4.)
* Added operator=(), operator==() and operator!=() to BShape.
* Added BShape::BezierTo() version taking three points, which is sometimes
more convenient.
* Added the four new shape data ops OP_LARGE_ARC_TO_CW, OP_LARGE_ARC_TO_CCW,
OP_SMALL_ARC_TO_CW and OP_SMALL_ARC_TO_CCW. For a single arc, provided the
radius is large enough, there are four possibilities to draw the arc, these
are controlled by the two boolean flags to ArcTo() and mapped to the new
commands accordingly.
* Some style cleanup in Shape.cpp (sorry for mixing it up, but it gets
worse below...)
* Added ShapeTest to src/tests/servers/app.
* Changed the way BShapes are transformed from view to screen space in the
app_server. For arcs, it would be nontrivial to apply a proper transformation,
it's much easier to let AGG take care of it. This affects ServerPicture as
well.
* Wrapped iterating the BShape into try/catch blocks in ShapeIterator. But
I really don't understand the purpose of the class in the first place.
Maybe it can now be dropped, since coordinates don't have to be transformed
in place anymore.
* Refactored copy&paste shape iteration code in Painter. The transformation
to screen space happens there.
* Since RemoteDrawingEngine needed to be adopted anyway, I also updated
it for the new DrawString() with offsets version. But the client still needs
to be adapted.
* Style cleanup in Painter.h

* Extended open() and open_from() to support O_CREAT to create files.
open_from() has got an optional "permissions" parameter for that purpose.
* Fixed errno. It would crash when being used. Also changed the POSIX functions

* Added writev().
* FAT file system:
- Added support for reading long file names.
- Added support for creating files (8.3 name only) and writing to them.
- Enabled scanning partitions with it.

- Enabled the "Reboot" menu item unconditionally.
- Added "Save syslog from previous session" menu item to the debug menu.
Currently saving the syslog to FAT32 volumes is supported.

received, but if the signal was in the thread's signal block mask, it would
not be handled. Added thread::sig_temp_enabled, an additional mask of not
blocked signals, which is set by sigsuspend() and evaluated and reset by
handle_signals(). Fixes#5567.

* The kernel syslog ring buffer is no longer emptied by the syslog sender
thread. Instead we only drop the oldest data from the buffer when we're
writing to it and there's not enough free space in it.
Advantages: We drop old data rather than the most recent data when the buffer
is full. The "syslog" KDL command has more data available now. So the odds
are that kernel syslog messages not written to disk yet are at least still
in the kernel buffer.
* Changed dprintf_no_syslog() semantics: Now it writes to the syslog, but
doesn't notify the syslog sender thread.
boot loader:
* Added the ring_buffer implementation and a dummy user_memcpy().
* bios_x86: Moved the syslog stuff from serial.{cpp,h} to debug.{cpp.h}.
* Moved the debug options from the "Select safe mode options" menu to a new
"Select debug options" menu.
* Added option "Enable debug syslog" to the new menu (ATM available on x86
only). It allocates a 1 MB in-memory buffer for the syslog for this session
in such a way that it can be accessed by the boot loader after a reset.
* Added item "Display syslog from previous session" to the new menu, doing
what its name suggests.

* Reused the existing mechanism to to have hardcoded tokens for the system
cursors, i.e. removed cursor_which enumeration from ServerProtocol.h and
used BCursorID where cursor_which was previously used.
* Reworked CursorManager.h and CursorSet.h accordingly and removed some methods
that where intended to replace system cursors with client cursors, since
those would break the reference counting and forget to maintain the cursor
list.
* Replaced the cursors in CursorData.h/cpp with the new ones I just designed.
* Removed HaikuSystemCursor.h and HaikuLogo.h from the source, as those are/were
no longer used.
I hope I will not get too much beating for this one... :-) I know the new
default cursor is slightly larger, but I believe the old one was just too small.
Also I noticed that the cursor may be slightly too dark, at least the old one
seems noticeably brighter when compared side by side (the new one has a slight
gradient). That is something I may correct at least. Otherwise I hope nothing
is broken, I've tested in QEMU and so far everything works as intended.

* Extended BTime, BDate and BDateTime with archiving functionality.
* Adjusted code which uses these classes, since including DateTime.h
already imports the classes from the BPrivate namespace.
* Moved DateTime.h into Support Kit. It is still in the BPrivate namespace,
as I am uncertain what to do with time_type and diff_type. I'd favor
moving the constants into the classes itself. Possibly removing the B_
prefix from them. Feedback welcome.

* Made the page table allocation more flexible. Got rid of sMaxVirtualAddress
and added new virtual_end address to the architecture specific kernel args.
* Increased the virtual space we reserve for the kernel to 16 MB. That
should suffice for quite a while. The previous 2 MB were too tight when
building the kernel with debug info.
* mmu_init(): The way we were translating the BIOS' extended memory map to
our physical ranges arrays was broken. Small gaps between usable memory
ranges would be ignored and instead marked allocated. This worked fine for
the boot loader and during the early kernel initialization, but after the
VM has been fully set up it frees all physical ranges that have not been
claimed otherwise. So those ranges could be entered into the free pages
list and would be used later. This could possibly cause all kinds of weird
problems, probably including ACPI issues. Now we add only the actually
usable ranges to our list.
Kernel:
* vm_page_init(): The pages of the ranges between the usable physical memory
ranges are now marked PAGE_STATE_UNUSED, the allocated ranges
PAGE_STATE_WIRED.
* unmap_and_free_physical_pages(): Don't free pages marked as unused.

happen on syscalls or "int" instructions. The debug exception handler sets
the thread debug flags B_THREAD_DEBUG_STOP and
B_THREAD_DEBUG_NOTIFY_SINGLE_STEP (new) and lets the thread continue. Before
leaving the kernel the thread is stopped and a single-step notification is
sent. Fixes#3487.

they were never freed unless the cache was destroyed (I just wondered why
my system would bury >1G in the magazines).
* Made the magazine capacity variable per cache, ie. for larger objects, it's
not a good idea to have 64*CPU buffers lying around in the worst case.
* Furthermore, the create_object_cache_etc()/object_depot_init() now have
arguments for the magazine capacity as well as the maximum number of full
unused magazines.
* By default, you might want to initialize both to zero, as then some hopefully
usable defaults are computed. Otherwise (the only current example is the
vm_page_mapping cache) you can just put in the values you'd want there.
The page mapping cache uses larger values, as its objects are usually
allocated and deleted in larger chunks.
* Beware, though, I couldn't test these changes yet as Qemu didn't like to run
today. I'll test these changes on another machine now.

needs to be or'ed to the address specification), "uncached" is assumed.
* Set the memory type for the "BIOS" and "DMA" areas to write-back. Not sure, if
that's correct, but that's what was effectively used on my machines before.
* Changed x86_set_mtrrs() and the CPU module hook to also set the default memory
type.
* Rewrote the MTRR computation once more:
- Now we know all used memory ranges, so we are free to extend used ranges
into unused ones in order to simplify them for MTRR setup.
- Leverage the subtractive properties of uncached and write-through ranges to
simplify ranges of any other respectively write-back type.
- Set the default memory type to write-back, so we don't need MTRRs for the
RAM ranges.
- If a new range intersects with an existing one, we no longer just fail.
Instead we use the strictest requirements implied by the ranges. This fixes
#5383.
Overall the new algorithm should be sufficient with far less MTRRs than before
(on my desktop machine 4 are used at maximum, while 8 didn't quite suffice
before). A drawback of the current implementation is that it doesn't deal with
the case of running out of MTRRs at all, which might result in some ranges
having weaker caching/memory ordering properties than requested.

* Fix the TimeFormat API, there was a double free. Make it work as expected : you send it a number of seconds and it will format it properly in days, hours, minutes, seconds with proper plural.
* Cleanup other parts of the Format API from useless things. They may get reintroduced later if we feel the need to do so.
* AboutSystem now use TimeFormat to display the uptime in properly localized way.

keeping all returned heap memory in the 0xdeadbeef state (including the
first sizeof(void *) bytes otherwise for the free list). While wasting a lot
of memory it allows you to rely on 0xdeadbeef being always present as no
future allocation will reuse the freed memory block.
* Also added heap_debug_malloc_with_guard_page() which is intended to allocate
a memory block so it is aligned that the start of invalid memory past the
allocation is in an unmapped guard page. However the kernel backend that would
guarantee this is not yet implemented, so right now this works only by chance
if no other area happens to be allocated exactly past the created one. With a
very specifc suspicion you can put that one allocation you get to good use
though. It causes a crash when accessing memory past the allocation size so
you actually get a backtrace from where the access happened instead of only
after freeing/wall checking.

* Moving some functions around, removing and adding others for the public API.
I've written a blog post at haiku-os.org to go as documentation for this
introducing the API and the other helpful bits.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35418 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added vm_clear_page_mapping_accessed_flags() and
vm_remove_all_page_mappings_if_unaccessed(), which combine the functionality
of vm_test_map_activation(), vm_clear_map_flags(), and
vm_remove_all_page_mappings(), thus saving lots of calls to translation map
methods. The backend is the new method
VMTranslationMap::ClearAccessedAndModified().
* Started to make use of the cached page queue and changed the meaning of the
other non-free queues slightly:
- Active queue: Contains mapped pages that have been used recently.
- Inactive queue: Contains mapped pages that have not been used recently. Also
contains unmapped temporary pages.
- Modified queue: Contains unmapped modified pages.
- Cached queue: Contains unmapped unmodified pages (LRU sorted).
Unless we're actually low on memory and actively do paging, modified and
cached queues only contain non-temporary pages. Cached pages are considered
quasi free. They still belong to a cache, but since they are unmodified and
unmapped, they can be freed immediately. And this is what
vm_page_[try_]reserve_pages() do now when there are no more actually free
pages at hand. Essentially this means that pages storing cached file data,
unless mmap()ped, no longer are considered used and don't contribute to page
pressure. Paging will not happen as long there are enough free + cached pages
available.
* Reimplemented the page daemon. It no longer scans all pages, but instead works
the page queues. As long as the free pages situation is harmless, it only
iterates through the active queue and deactivates pages that have not been
used recently. When paging occurs it additionally scans the inactive queue and
frees pages that have not been used recently.
* Changed the page reservation/allocation interface:
vm_page_[try_]reserve_pages(), vm_page_unreserve_pages(), and
vm_page_allocate_page() now take a vm_page_reservation structure pointer.
The reservation functions initialize the structure -- currently consisting
only of a count member for the number of still reserved pages.
vm_page_allocate_page() decrements the count and vm_page_unreserve_pages()
unreserves the remaining pages (if any). Advantages are that reservation/
unreservation mismatches cannot occur anymore, that vm_page_allocate_page()
can verify that the caller has indeed a reserved page left, and that there's
no unnecessary pressure on the free page pool anymore. The only disadvantage
is that the vm_page_reservation object needs to be passed around a bit.
* Reworked the page reservation implementation:
- Got rid of sSystemReservedPages and sPageDeficit. Instead
sUnreservedFreePages now actually contains the number of free pages that
have not yet been reserved (it cannot become negative anymore) and the new
sUnsatisfiedPageReservations contains the number of pages that are still
needed for reservation.
- Threads waiting for reservations do now add themselves to a waiter queue,
which is ordered by descending priority (VM priority and thread priority).
High priority waiters are served first when pages become available.
Fixes#5328.
* cache_prefetch_vnode(): Would reserve one less page than allocated later, if
the size wasn't page aligned.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35393 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Remove no longer necessary support functions.
* The new version uses a single BString as input/output parameter and only
modifies that one by removing non-fitting chars and inserting the ellipsis
where appropriate, so avoids copying around bytes/chars/strings in a few
places. It uses the new Chars functions of BString so also no need for manual
multibyte handling.
* Adjusted the BFont and ServerFont usage of truncate_string() which are both
simplified by using the single BString. It avoids a lot of temprary
allocations and string copying. The char * version of BFont
GetTruncatedStrings() now uses the BString version and not the other way
around anymore which requires us to allocate temporary BString objects, it's
not worse than before though.
* This fixes a bunch of problems with the previous functions like always
prepending the ellipsis for B_TRUNCATE_BEGINNING, crashing on short enough
widths, violating the width in the B_TRUNCATE_END case when the width was
short enough, non-optimal truncation in a few cases and sometimes truncation
where none would've been needed. Also fixes#4128 which was a symptom of the
broken B_TRUNCATE_BEGINNING.

the corresponding normal functions but have a "Chars" in the name like
"MoveCharsInto" or "AppendChars". Also added CountBytes() and CharAt().
This should make everyday string handling with multibyte strings a bit easier.

general "flags" parameter. It encodes the target state of the page -- so
that the page isn't unnecessarily put in the wrong page queue first -- a
flag whether the page should be cleared, and one to indicate whether the
page should be marked busy.
* Added page state PAGE_STATE_CACHED. Not used yet.

flag. The obvious advantage is that one can still see what state a page is in
and even move it between states while being marked busy.
* Removed the vm_page::is_dummy flag. Instead we mark marker pages busy, which
in all cases has the same effect. Introduced a vm_page_is_dummy() that can
still check whether a given page is a dummy page.
* vm_page_unreserve_pages(): Before adding to the system reserve make sure
sUnreservedFreePages is non-negative. Otherwise we'd make nonexisting pages
available for allocation. steal_pages() still has the same problem and it
can't be solved that easily.
* map_page(): No longer changes the page state/mark the page unbusy. That's the
caller's responsibility.

argument. They replace the previous special-purpose allocation functions
(malloc_nogrow(), vip_io_request_malloc()).
* Moved the I/O VIP heap to heap.cpp accordingly.
* Added quite a bit of passing around of allocation flags in the VM,
particularly in the VM*AddressSpace classes.
* Fixed IOBuffer::GetNextVirtualVec(): It was ignoring the VIP flag and always
allocated on the normal heap.

memory and page reservation functions have a new "priority" parameter that
indicates how deep the function may tap into that reserve. The currently
existing priority levels are "user", "system", and "VIP". The idea is that
user programs should never be able to cause a state that gets the kernel into
trouble due to heavy battling for memory. The "VIP" level (not really used
yet) is intended for allocations that are required to free memory eventually
(in the page writer). More levels are thinkable in the future, like "user real
time" or "user system server".
* Added "priority" parameters to several VMCache methods.
* Replaced the map_backing_store() "unmapAddressRange" parameter by a "flags"
parameter.
* Added area creation flag CREATE_AREA_PRIORITY_VIP and slab allocator flag
CACHE_PRIORITY_VIP indicating the importance of the request.
* Changed most code to pass the right priorities/flags.
These changes already significantly improve the behavior in low memory
situations. I've tested a bit with 64 MB (virtual) RAM and, while not
particularly fast and responsive, the system remains at least usable under high
memory pressure.
As a side effect the slab allocator can now be used as general memory allocator.
Not done by default yet, though.

* Added support to do larger raw allocations (up to one large chunk (128 pages))
in the slab areas. For an even larger allocation an area is created (haven't
seen that happen yet, though).
* Added kernel tracing (SLAB_MEMORY_MANAGER_TRACING).
* _FreeArea(): Copy and paste bug: The meta chunks of the to be freed area
would be added to the free lists instead of being removed from them. This
would corrupt the lists and also lead to all kinds of misuse of meta chunks.
object caches:
* Implemented CACHE_ALIGN_ON_SIZE. It is no longer set for all small object
caches, but the block allocator sets it on all power of two size caches.
* object_cache_reserve_internal(): Detect recursion and don't wait in such a
case. The function could deadlock itself, since
HashedObjectCache::CreateSlab() does allocate memory, thus potentially
reentering.
* object_cache_low_memory():
- I missed some returns when reworking that one in r35254, so the function
might stop early and also leave the cache in maintenance mode, which would
cause it to be ignored by object cache resizer and low memory handler from
that point on.
- Since ReturnSlab() potentially unlocks, the conditions weren't quite correct
and too many slabs could be freed.
- Simplified things a bit.
* object_cache_alloc(): Since object_cache_reserve_internal() does potentially
unlock the cache, the situation might have changed and their might not be an
empty slab available, but a partial one. The function would crash.
* Renamed the object cache tracing variable to SLAB_OBJECT_CACHE_TRACING.
* Renamed debugger command "cache_info" to "slab_cache" to avoid confusion with
the VMCache commands.
* ObjectCache::usage was not maintained anymore since I introduced the
MemoryManager. object_cache_get_usage() would thus always return 0 and the
block cache would not be considered cached memory. This was only of
informational relevance, though.
slab allocator misc.:
* Disable the object depots of block allocator caches for object sizes > 2 KB.
Allocations of those sizes aren't so common that the object depots yield any
benefit.
* The slab allocator is now fully self-sufficient. It allocates its bootstrap
memory from the MemoryManager, and the hash tables for HashedObjectCaches use
the block allocator instead of the heap, now.
* Added option to use the slab allocator for malloc() and friends
(USE_SLAB_ALLOCATOR_FOR_MALLOC). Currently disabled. Works in principle and
has virtually no lock contention. Handling for low memory situations is yet
missing, though.
* Improved the output of some debugger commands.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35283 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added optional parameter "void** oldTable" to Resize(). If given the old
allocation for the table is returned instead of freeing it.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35278 a95241bf-73f2-0310-859d-f6bbb57e9c96
(This one takes care of setting up the correct color.)
* Added TODO about using either B_CONTROL_TEXT_COLOR, or elliminating that
constant (which I am in favor of...).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35260 a95241bf-73f2-0310-859d-f6bbb57e9c96
CACHE_DONT_LOCK_KERNEL_SPACE. If the former is given, the slab memory manager
does not wait when reserving memory or pages. The latter prevents area
operations. The new flags add a bit of flexibility. E.g. when allocating page
mapping objects for userland areas CACHE_DONT_WAIT_FOR_MEMORY is sufficient,
i.e. the allocation will succeed as long as pages are available.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35246 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented a more elaborated raw memory allocation backend (MemoryManager).
We allocate 8 MB areas whose pages we allocate and map when needed. An area is
divided into equally-sized chunks which form the basic units of allocation. We
have areas with three possible chunk sizes (small, medium, large), which is
basically what the ObjectCache implementations were using anyway.
* Added "uint32 flags" parameter to several of the slab allocator's object
cache and object depot functions. E.g. object_depot_store() potentially wants
to allocate memory for a magazine. But also in pure freeing functions it
might eventually become useful to have those flags, since they could end up
deleting an area, which might not be allowable in all situations. We should
introduce specific flags to indicate that.
* Reworked the block allocator. Since the MemoryManager allocates block-aligned
areas, maintains a hash table for lookup, and maps chunks to object caches,
we can quickly find out which object cache a to be freed allocation belongs
to and thus don't need the boundary tags anymore.
* Reworked the slab boot strap process. We allocate from the initial area only
when really necessary, i.e. when the object cache for the respective
allocation size has not been created yet. A single page is thus sufficient.
other:
* vm_allocate_early(): Added boolean "blockAlign" parameter. If true, the
semantics is the same as for B_ANY_KERNEL_BLOCK_ADDRESS.
* Use an object cache for page mappings. This significantly reduces the
contention on the heap bin locks.

- Some changes in the locale roster to allow instanciating a language
- Locale preflet : use this new API instead of directly calling ICU

one for each per CPU store):
* The depot is now protected by a R/W lock combined with a spinlock. It is
required to either hold read lock + spinlock or just the write lock.
* When accessing the per CPU stores we only need to acquire the read lock
and disable interrupts. When switching magazines with the depot we
additionally get the spinlock.
* When allocating a new magazine we do completely unlock.

team_shutdown_team()), before removing the team from the team hash and from
its process group. This fixes#5296.

threads to die. We notify the condition right after a thread has left the
team. The semaphore was released by the undertaker.
