* 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.

the contiguous page allocation function and unlocks a bin locker a bit earlier.

* Make the contiguous page allocation capable of aligning the allocation
and make it more clever by checking up front if there's a chance of getting
enough pages at all, by giving up earlier if the page count can't be fit
anymore, and in the alignment case by only checking the pages which have a
valid alignment.
* If the alignment requirement is > B_PAGE_SIZE we now use page allocation
directly, because the bins aren't necesarily aligned on their size past
B_PAGE_SIZE anymore.
* When doing aligned bin allocation, calculate the aligned size up front and
choose the right heap for the allocation.
* Also when doing aligned bin allocations we not only need to round up the size
but also ensure that the bin we choose is aligned at all.
* Moved adding leak check info into it's own function.
Fixes various misalignment problems when working with alignments > B_PAGE_SIZE
or when using alignments < allocation size. Also the directly aligned page
allocations now only use up as many pages as actually required instead of
allocating based on the rounded up to align size.

When initializing driver settings, make sure to set the parameter count to 0,
because these settings have not been parsed yet. This allows us to safely free
the settings. Freeing the settings is triggered in load_driver_settings() if
we encounter settings which have been originally loaded by the boot_loader,
which might be stale. I think the bug would trigger for settings which had been
loaded by the boot_loader but had never been parsed.
With this change, I can use the userlandfs on all my machines.

Also added an empty stub for _thread_do_exit_notification() when compiling for GCC2.
* Removed the check testing if the thread is already dead.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35142 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Moved the "tmp" directory out of /var, and to /boot/common/cache/.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35104 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implementations of pthread_getschedparam and pthread_setschedparam I had since a while.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35098 a95241bf-73f2-0310-859d-f6bbb57e9c96
Update filesystem name in find_directory as our fat filesystem is not named "dos".
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@35093 a95241bf-73f2-0310-859d-f6bbb57e9c96
* relocated Trash dirs to volume roots by modifying find_directory() to report the trash location as volume/Trash.
* FSUtils no longer creates /home/Desktop on every volume.
* TrashWatcher now keeps icons in sync on all volumes.
* Simplified FSGetDeskDir since it no longer has to worry about getting the desk directory on any volume other than the root.
* Relocated trash context menu logic to BContainerWindow so it can also be used at the volume roots.
* DesktopPoseView now creates a virtual Trash pose representing the trash contents as before.
* Corrected typo: Model::WriteAttrKillForegin() -> Model::WriteAttrKillForeign().
Closes ticket #5245.

sHeapBase will probably not point to memory in the heap area. Use
sFreeHeapBase instead.
* When reserving the heap area range fails, set sHeapBase to NULL, so we'll
later know about the fact.
* hoardSbrk(): When resizing the area fails, we'll now try to allocate a new
one, if the former failure was not due to an "out of memory" situation.
E.g. if the heap range reservation failed or, if we just have exhausted the
range, another area could be in the way. Also when mmap()ing over
malloc()ed, the heap area count be split in two with the first part
retaining the old area ID, thus preventing resizing as well. Fixed#5168.

it do that? This fixes the kernel build, and probably GCC4, too.

debug heap implementation.
* Added libroot_debug.so to the DevelopmentMin optional package. Since it has
the same soname as the standard libroot, it can simply be specified in
LD_PRELOAD to run a program with that version.

system_time_nsecs(), returning the system time in nanoseconds. The function
is only really implemented for x86. For the other architectures
system_time() * 1000 is returned.

difference that the initialization function has an additional void* argument,
so that it is suitable for initializing stuff in objects.

* Split locks.cpp into mutex.cpp, recursive_lock.cpp, and rw_lock.cpp (new
subdirectory locks/).
* runtime_loader no longer includes the rw_lock, allowing removal of the TLS
dependency again.

to the specs, the application may still use the FD without changing its state,
and only closedir() should finally close it.
* This fixes bug #5055.

recursive lock. I haven't investigated it closer, but the previous
implementation was even broken -- "strace /bin/true" showed two
release_sem() calls, but no acquire_sem().

as a mutex, but allocates its semaphore lazily. This comes at the cost of an
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.

* Fixed check in hoardSbrk(): resize_area() was invoked, even if the area was
already large enough.
* Increased the initial heap size to 64 pages. Apparently the hoard
implementation is rather generous and the first malloc() (caused by
__init_heap()) already required enlarging the area.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34336 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Implemented renameat(), faccessat(), fchownat(), fchmodat(), and mkfifoat().
* Added stub for mknodat().
* The kernel backend for faccessat() does not yet differentiate between
effective and real user/group IDs, though.
* Removed B_ENABLE_INCOMPLETE_POSIX_AT_SUPPORT, as we now support everything
(more or less). This also closes ticket #4928.

PThreads didn't have their array for the TLS values initialized.
From what we can tell, this would have been a problem for any program using
pthreads, but since all threads are pthreads now, it was much more likely to
be encountered. Like in Beam as reported in #4949 (which via libbind seems
to use some pthread stuff).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34161 a95241bf-73f2-0310-859d-f6bbb57e9c96
as long as the full set hasn't been implemented. They are guarded by the
B_ENABLE_INCOMPLETE_POSIX_AT_SUPPORT macro until then. Fixes the build.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33990 a95241bf-73f2-0310-859d-f6bbb57e9c96
* /etc now points to /boot/common/etc/, and the remaining contents of the former
"etc" are put there now, as well.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33986 a95241bf-73f2-0310-859d-f6bbb57e9c96
directory, where they were misplaced, and joined them to fcntl.cpp.
* Added openat().
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33976 a95241bf-73f2-0310-859d-f6bbb57e9c96
returned by open() aren't suitable for directory iteration and because checks
have to be performed (like whether this is a directory at all and whether the
user has read permission).
* Added __create_dir_struct() for the attribute, index, and query open
functions to use instead.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@33974 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Therefore, all pthread functions should now work fine on all threads.
