changes the semantics slightly: Previously after a failed initialization
another invocation of InitializeDefault() could theoretically initialize the
converter. Since the only error conditions are out of memory and broken app
server connection, this shouldn't really matter, though.

relatively expensive (uname()) and used already in the libbe

additional atomic_add() when the semaphore has actually to be acquired, but
saves the semaphore creation completely in single-threaded programs and in
any program when there's no lock contention.

* Added stub for mknodat().
* The kernel backend for faccessat() does not yet differentiate between
effective and real user/group IDs, though.

(more or less). This also closes ticket #4928.

* Moved O_NOCACHE, and O_NOFOLLOW to the section with implemented modes.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34243 a95241bf-73f2-0310-859d-f6bbb57e9c96

and types.h. The idea is to provide a basic architecture/compiler
abstraction by defining types and macros that allow the posix/ and os/
headers to be mostly architecture/compiler agnostic.
* Adjusted the posix/ and os/ headers accordingly.
* <SupportDefs.h>: Introduced B_PRI* and B_SCN* macros similar to the PRI*
and SCN* macros defined in <inttypes.h>, just for the BeOS/Haiku [u]int*
types and some POSIX types (e.g. off_t, dev_t, ino_t) that don't have POSIX
macros. Also the B_PRI* and B_SCN* macros are available unconditionally,
unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
defined in C++ mode.

checking the physical frame buffer location.
* This allows us to map the whole frame buffer at once, which means there is no
need anymore to remap the memory on mode change.
* Also, this will ease the burden of the MTRRs, as the memory size will be
properly aligned.

all MTRRs at once.
* Added a respective x86_set_mtrrs() kernel function.
* x86 CPU module:
- Implemented the new hook.
- Prefixed most debug output with the CPU index. Otherwise it gets quite
confusing with multiple CPUs.
- generic_init_mtrrs(): No longer clear all MTRRs, if they are already
enabled. This lets us benefit from the BIOS's setup until we install our
own -- otherwise with caching disabled things are *really* slow.
* arch_vm.cpp: Completely rewrote the MTRR handling as the old one was not
only slow (O(2^n)), but also broken (resulting in incorrect setups (e.g.
with cachable ranges larger than requested)), and not working by design for
certain cases (subtractive setups intersecting ranges added later).
Now we maintain an array with the successfully set ranges. When a new range
is added, we recompute the complete MTRR setup as we need to. The new
algorithm analyzing the ranges has linear complexity and also handles range
base addresses with an alignment not matching the range size (e.g. a range
at address 0x1000 with size 0x2000) and joining of adjacent/overlapping
ranges of the same type.
This fixes the slow graphics on my 4 GB machine (though unfortunately the
8 MTRRs aren't enough to fully cover the complete frame buffer (about 35
pixel lines remain uncachable), but that can't be helped without rounding up
the frame buffer size, for which we don't have enough information). It might
also fix#1823.

- Rename "Configure Favorites..." to "Edit Favorites...".
- Remove the old-style Configure Favorites dialog in favor of simply
opening the favorites folder (~/config/settings/Tracker/go) in a
Tracker window for the user to manipulate.
- Rename the "Favorite Folders" section to simply "Favorites" as files
are also allowed (i.e. to easily open a template document).
- Removed completely arbitrary (and silent) 20 item limit to favorites
list.
- Automatic whitespace cleanup
Still to do: Grab the ref filter from the file panel (if any) and run the
favorites through it as well, since we want to filter out any non-folder
favorites that the app is incapable of handling. Also, the setting for
the favorites menu to show recent documents needs a new home, as it was
previously in the no longer existing Configure Favorites window. Suggestions
welcome, as I'm not currently seeing a spot in the Tracker prefs that would
make good sense.

* When DEBUG_SPINLOCK_LATENCIES is 1, the system will panic if any spinlock is
held longer than DEBUG_LATENCY micro seconds (currently 200). If your system
doesn't boot anymore, a new safemode setting can disable the panic.
* Besides some problems during boot when the MTRRs are set up, 200 usecs work
fine here if all debug output is turned off (the output stuff is definitely
problematic, though I don't have a good idea on how to improve upon it a lot).
* Renamed the formerly BeOS compatible safemode settings to look better; there
is no need to be compatible there.

KDEBUG=2) on my laptop.

(hopefully) correct place.
* It seems to be even harder to understand basic locking primitives: when you
think about it, it shouldn't surprise you that conditional variables never
return B_WOULD_BLOCK. This fixes gdb again.
* Added tracing support to the ports subsystem.
* get_port_message() will now resize the port heap if needed (but will also
take timeouts into account while doing so, more or less). The initial port
space is 4MB (as before), the growth rate is the same, and the system wide
limit is arbitrarily set to 64 MB (all swappable). A team limit has been set
to 8 MB, but is not enforced yet. Since ports are using up address space in
the kernel, those seems to be proper limits.
* This also fixes a strange, and rare lockup where the mouse cursor would still
move, but everything else would basically hang, but look perfectly normal from
KDL on the first look. As recently happened on Brecht's laptop, and debugged
by mmlr and me: the cbuf space got used up when lots of windows wanted to
redraw after a workspace switch. The app_server wouldn't answer anymore to
client requests, but thought it would have done so, as LinkSender::Flush()
doesn't care if it got a B_NO_MEMORY (the ports will now block until memory
is available if possible, so that should not be a problem anymore).
* Improved "port" KDL command, it now also prints the messages in the port.

* its own heap allocator instead of cbuf - this makes cbuf superfluous, and I
therefore removed it from the kernel. The heap is swappable, so lifts the
kernel's resource usage a bit. In the future, the heap should grow as well;
right now it should be at least as good as before.
* it no longer uses spinlocks, but just mutexes now for better scalability - it
was not usable with interrupts turned off anyway (due to its semaphore usage).
* it no longer uses semaphores, but condition variables.
* Needed to move the port initialization to a later point, as swappable memory
wasn't usable that early.
* All ports test are still passing, hopefully I didn't mess anything up :-)

libroot. The mutex is a simple benaphore, the rw_lock is pretty much the same
as the one from libkernelland_emu but uses a mutex per lock instead of emulating
a global thread lock. Also added MutexLocking and RWLock{Read|Write}Locking and
AutoLockers based on them. It's cased with __cplusplus so the locks are also
usable from C. Everything's currently exposed in shared/private/locks.h but I
think we should make these locking primitves public.

are required to be physically contiguos, which should be reworked to put them
into seperate iovecs. Still this manages to combine a great deal of page
writes into larger bursts already. Reduces the amount of IO requests being
scheduled (and greatly benefits media where page wise writes are slow when
they are accessed through a non-IOScheduler path, i.e. USB mass storage until
that is properly implemented).
* Abstracted per page page writing tasks into a PageWriteWrapper class.
* Abstracted per transfer page writing tasks into PageWriteTransfer class which
formerly was the PageWriterCallback.
* Use both classes from the PageWriterRun and from
vm_page_write_modified_page_range to remove code duplication.
* Adjusted synchronous VMAnonymousCache::Write() to cope correctly with larger
iovecs and more than one iovec. It assumed that there was exactly one page per
vector previously.
* Introduced MaxPagesPerWrite() and MaxPagesPerAsyncWrite() to VMCache to allow
a cache to specify restricitions. VMAnonymousCache does restrict the max pages
to 1 for WriteAsync right now as I didn't feel like reworking that one to cope
with non single page writes just yet.
* Pulled out PageWriteTransfer methods for better readability.

importantly block until the operation is done (waiting for the reply).
