* Renamed time.c to time.cpp.
* set_timezone() now uses localtime_r() instead of localtime(), and will also
no longer fail in case there was no timezone symlink before.
* Cleaned up OS.h header.

* Minor cleanup.

* Always use _kern_create_attr() in fs_write_attr(), or otherwise it might not
be created when it should.
* Stippi special: fixed typo "in another words" -> "in other words" ("a" is
singular, not plural).

* As even the author of fs_attr.c was trying to use fs_write_attr() in an
unsupported way in the cp copy_attributes() implementation, try to be
more forgiving and support writing attributes at an offset. The method is
required to behave inconsistent in that replacing bytes at offset 0 is
not supported as replacing bytes at any other offset. Writing at offset 0
will clobber the existing attribute to stay compatible with BeOS.
NOTE: BFS itself still does not support writing attributes at an offset which
are withing the "small data section". To work around this problem, programs
which copy attributes in a loop must make sure that their buffer is large
enough that such "small data section" attributes require only one loop
iteration.

the node listener, to make sure it won't lose track.
* The DriverWatcher now also listens for B_ENTRY_REMOVED. This causes drivers to
be unpublished even if they are only symlinked.
* However, to detect new drivers in a symlinked location, we'd need special
support for those, and also need to watch the parent directory of the symlink
target - this is close to overkill, so I stayed away from implementing that
for now :-)

is a syscall iframe.
* User debugger support: Don't to call BreakpointManager::PrepareToContinue(),
if the thread returns from a syscall. We don't want to skip breakpoints in
that case.

* The bulk of the work -- i.e. juggling the software and hardware breakpoints,
watchpoints, and memory reads/writes -- is done in the new class
BreakpointManager.
* For the architectures a few capability macros have to be defined, one
pointing to the software breakpoint instruction opcode. Done for x86.
* Some more simplifications in the user debugger code, made possible by the
recently introduced debugger_changed_condition attribute.

installed team debugger and adjusted the code accordingly. It's not needed yet,
but I intend to add support for software breakpoints and those require a bit of
uninitialization that needs to be synchronized with debugger changes and can't
be done with interrupts disabled.

and added a _kern_unreserve_address_range() as well.
* The runtime loader now reserves the space needed for all its areas first
to make sure there is enough space left for all areas of a single image.
* This also fixes the final part of bug #4008.
* Minor cleanup.

make Clockwerk run okay with any number of translators (even if not all of
them will work yet).

* It was broken since the support for debugger handovers. Using
debugger_write() couldn't work, since the thread didn't belong to the
debugged team anymore (but to the kernel) and thus getting the debug info
for team would always fail. This makes B_DEBUGGER_MESSAGE_THREAD_DELETED
notifications work again.
* Allow the thread to block. Locking/writing to the port was non-blocking
before, but there shouldn't be a problem, if the thread has to wait.

anyway, we also risk filling the port and blocking the nub thread.

* Generalized address checks. The debugger can now also read the commpage.
* Added new syscall _kern_get_thread_cpu_state() to get the CPU state of a
not running thread. Introduced arch_get_thread_debug_cpu_state() for that
purpose, which is only implemented for x86 ATM (uses the new
i386_get_thread_user_iframe()).
* Don't allow a debugger to change a thread's "esp" anymore. That's the esp
register in the kernel. "user_esp" can still be changed.
* Generally set RF (resume flag) in eflags in interrupt handlers, not only
after a instruction breakpoint debug exception. This should prevent
breakpoints from being triggered more than once (e.g. when the breakpoint is
on an instruction that can cause a page fault). I still saw those with bdb
in VMware, but that might be a VMware bug.

first run only set up uncacheable MTRRs and in the second run set the write-back
ones up. If this order is not followed, we could set too large ranges to
cacheable first and then limit it back to uncacheable later. On systems with
enough physical memory this would lead to a temporary situation in which areas
become cacheable that must not be, resulting in system hangs or other unexpected
behaviour. Fixes last part of #4018.

boot device is actually read-only (even if it's using the write overlay).
* Do not create a swap file on a read-only device - this would really be a
stupid use of the write overlay (just saw this happening on an older
machine).
* Made swap_file_{add|delete}() take a const char* path - there was no reason
this was writable, and this also avoids casting away the const when adding
the default swap file.
* Minor cleanup.

decided to recursively resolve a symlink. We only have to do the resolution
when the flag is true anyway or the symlink is not the last component of
our path, in which case we have to resolve it anyway. Fixes#3986.

- While walking down the cache chain, we keep all upper caches locked.
- When we have to unlock -- when waiting for a busy page or reading a page in
-- we unlock completely, including the address space, and restart
vm_soft_fault().
- Folded fault_get_page() and fault_find_page() into one.
This simplifies and improves things considerably:
- We no longer need dummy pages.
- We no longer need vm_area::no_cache_change.
- #2710 is fixed, since we no longer hold the address space lock while
waiting.
* vm_soft_fault(): When we have found our page, we first check whether a page
is already mapped at the address. If it is already our page, we just change
its protection. If not, we unmap it first. Fixes race conditions when multiple
threads fault at the same address at the same time.
* fault_get_page(): When copying a read-only page from a lower cache, no longer
mark it active, since at least for the fault area it is shadowed from then on.
* vm_set_area_protection(): Fixed potential overflow for in the
vm_translation_map::protect() call.

it prints an even nicer stack trace. Not removing the code yet to make things
easier for architectures on which we don't have a userland yet.

This means that the workaround in mail_util.cpp of the mail kit could be
removed, but since I do not know if that should still support other versions
of BeOS, I have chosen to leave it alone.

replaced by timespec fields. Via macros the structure is still source
compatible with the old one.
* Introduced header <compat/sys/stat.h> that defines the old stat structure
(as stat_beos) and conversion functions
* Introduced versions for [l,f]stat().
* Added symbol versions for BDirectory::GetStatFor() for sake of binary
compatibility.
* BStatable::GetStat(): Renamed the old method, changed its parameter to
stat_beos*, and and made it private. Added a new version (using up a
reserved vtable slot). It remains source and binary compatible.
* BRefFilter::Filter(): Changed the struct stat* parameter to struct stat_beos*
for sake of binary compatibility. This breaks source compatibility, though,
which we can't help, since the class doesn't have reserved vtable slots.
* Fixed several issues with the stat structure change, mostly adjusted uses of
BRefFilter.
