- Fixed deadlock in xsi_sem_undo - RecordUndo
- Fixed issue in xsi_sem_undo: if the semaphore set does not exist
anymore, ignore the request but do remove the process from the sUndoList,
which wasn't previously done.
- free() in ClearUndos was called with interrupts disabled
- when a semaphore set ends to exist, remove all it's sem_undo request as it's ID
will be reused in the future.

* sCopied wasn't needed anymore due to the sManagedEnviron variable.
* Minor cleanup, added a description to copy_environ_to_heap_if_needed().

the environment would crash on Haiku. Added a small test application that
just checks every one of those.
* Fixed env locking (in userland, you better check against B_INTERRUPTED).
* Made our code safe against an environ of NULL.
* There is now an additional sManagedEnviron that points to the environment
our code actually managed; whenever an application overrides environ, we'll
get aware of it with the next *env() function invocation, and will handle
it adequately.
* Added non-POSIX clearenv() function.

by myself:
* renamed xsi_do_undo() to xsi_sem_undo() (there is more to XSI than sems).
* Fixed coding style issues in sys/sem.h and xsi_sem.cpp.
* Added _kern_*() syscall prototypes to syscalls.h.
* Added a TODO in xsi_sem.cpp and xsi_semaphore.h about moving union semun to
a shared header.
* Made the team::xsi_sem_undo_requests int32 - due to padding, it would have
needed 4 bytes anyway; please always use specific types over int/short/long.
* xsi_sem_undo() now checks if it needs to do anything - the calls in team.cpp
no longer needs to do this.

header.
* Added fields necessary to make it possible to retrieve more than one
dirent from the underlying file system.
* Unless some app creates a DIR on its own to it to feed readdir(), this
change should be binary compatible. If we find an application misbehaving,
we can still make it a GCC4 only thing.
* fs_attr/fs_index/fs_query now all use readdir() directly (as that one
contains the logic to iterate through a number of dirents in userspace).

* Since there is no "Haiku license", I replaced that with a reference to the
MIT license as usual.

a flattened argument/environment buffer now. This simplifies the work
for the kernel a bit, since it can just copy the buffer and check
whether it looks OK instead of messing around with individual strings.
The runtime loader also gets a flattened array.
* Set the maximum size of the arguments/environment buffer to 128 KB.
When more arguments are passed, we fail with a proper error code
(instead of just truncating the arguments as before).
* On exec*() the first argument was silently replaced by the given path
name, which is not correct.

and remove the then unneeded mutex_init() for them.
* Remove the workaround for allowing uninitialized mutexes on kernel startup.
As they are all initialized statically through the MUTEX_INITIALIZER() now
this is not needed anymore.
* An uninitialized mutex will now cause a panic when used to find possibly
remaining cases.
* Remove now unnecessary driver_settings_init_post_sem() function.

PTHREAD_SCOPE_SYSTEM which makes the implementation rather simple.
* This closed ticket #2242.

- *pathconf() now uses statvfs and fs_info data when appropriate. It should also check for file type though, some only apply to directory or others.
- added confstr(_CS_PATH) with a sensible default.

vm_page_write_modified_pages(), save that it only writes pages in the
given range.
* Added vm_page_schedule_write_page_range() which schedules all modified
pages in the given cache's range for writing by the page writer.
* Added _kern_sync_memory() syscall and the msync() POSIX function.

* Made the pthread_cond_t internals public. This is necessary to support
process shared condition variables. Fixed initializer macro.
* Made the pthread_rwlockattr_t structure opaque.
* pthread_t is no longer typedef'ed to int. It's the pointer to the
internal _pthread_thread structure.
* Removed __get_pthread(). pthread_self() can be used instead.
* No longer tunnel the pthread exit value through Haiku's thread exit
value. We do have a separate field in the _pthread_thread structure
for it, now.
* Handle detaching of threads correctly.
* pthread_rwlockattr_{g,s}etpshared() use the
PTHREAD_PROCESS_{SHARED,PRIVATE} constants, now.
* Commented out yet unsupported structures (barriers, spinlocks).
* Rebuilt APR optional package. The pthread changes weren't binary
compatible.

to contain headers shared by kernel and userland (mainly libroot).
* Moved quite a few private kernel headers to the new location. Split
several kernel headers into a shared part and one that is still kernel
private. Adjusted all affected Jamfiles and source in the standard x86
build accordingly. The build for other architectures and for test code
may be broken.
* Quite a bit of userland code still includes private kernel headers.
Mostly those are <util/*> headers. The ones that aren't strictly
kernel-only should be moved to some other place (maybe
headers/private/shared/util).

particularly efficient.
* pthread_mutex implementation:
- Removed the pthread_mutex_t indirection (the type was a pointer to
the actual structure which was allocated on the heap), as it made
sharing the mutex between processes impossible.
- Removed the distinction between process shared and non-shared
mutexes. Benaphores work just as well in shared memory, so we always
use them.
* Fixed some static initializer macros. PTHREAD_COND_INITIALIZER is
still broken, since it doesn't work in C code.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25481 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added comment clarifying the use of reader_count and writer_count.

and pthread_mutex_timedlock() which were waiting system time relative
although their timeout parameter is Epoch relative.

signal mask as required. and also makes my recent return value fix
unnecessary, since __longjmp_return() already does that.

arguments they get a single thread_creation_attributes structure now.
* Added stack_address and stack_size to thread_creation_attributes,
which allow to specify the stack size or the stack to be used for the
new user thread.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25389 a95241bf-73f2-0310-859d-f6bbb57e9c96
simply created as files in /boot/var/shared_memory/. The Bootscript
clears the directory.

* Changed the semantics of unnamed semaphores. Before parent and child
of a fork() would always share an earlier created semaphore. Now we do
that only, if the "shared" parameter of sem_init() was true. That's
still not quite the behavior Linux and Solaris have, but should be
perfectly fine with how reasonable code would use the API.
* There's a global table for shared unnamed semaphores now. ATM a
semaphore is leaked when no one explicitly destroys it (just as with
named sems).
* Enforce per-team and global semaphore number limits.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25362 a95241bf-73f2-0310-859d-f6bbb57e9c96
not supposed to be passed to pathconf() or sysconf().
* Added POSIX semaphore related macros.
