pthread: Use 1 for PTHREAD_BARRIER_SERIAL_THREAD.

pthread_barrier_wait can return errors, which on Haiku are negative
and so -1 is an error condition, it should not be reused for a magic
constant.

This breaks ABI. However, until the recent fixes, barriers were so broken
that I doubt any application was using them seriously (Mesa, for instance,
has them disabled.)

pthread_rwlock: use a mutex for process-private locks.

* instead of a benaphore.
* define PTHREAD_RWLOCK_INITIALIZER.
* adjust Init(), Destroy(), StructureLock() and StructureUnlock().

pthread.h: Remove PTHREAD_RWLOCK_INITIALIZER macro.

This reverts commit 17286dc70a81d1aa8d853a73db0b0ebe79e6ed9a.

As discussed on the mailing list. As it turns out, this was less
than half of an actual implementation of this macro, and there's
technically no way to implement it without introducing (theoretical)
race conditions, in the current design anyway.

pthread.h: Add PTHREAD_RWLOCK_INITIALIZER macro.

Signed-off-by: Augustin Cavalier <waddlesplash@gmail.com>
Fixes #8798. One tiny style fix by me (adding spaces around braces).

pthread: add const for pthread_mutex*_get*()

according to the spec. Fixes #13324.
* code style clean up.

libroot: Implemented pthread barriers

This is an implementation of pthread barriers pursuant to the relevant specification.

Barriers are essentially a special case of conditional variables,
such that all threads waiting on one are woken up when the number of
waiters reaches a number provided at the initialization of the barrier.
In view of that, this implementation mimics the implementation of pthread_cond,
except it is more specialized and self-contained.

* The thread_info::stack_base/end range now refers to the usable range

Merged signals-merge branch into trunk with the following changes:
* Reorganized the kernel locking related to threads and teams.
* We now discriminate correctly between process and thread signals. Signal
handlers have been moved to teams. Fixes #5679.
* Implemented real-time signal support, including signal queuing, SA_SIGINFO

* Rearranged pthread thread support a bit: there is now a pthread_thread
structure that is attached (via TLS) to each pthread.
* Implemented support for pthread_cleanup_{push|pop}().
* I haven't really been able to test these changes, yet, though.

POSIX headers should not include BeOS/Haiku headers. Should help with
flex's pthread test.

added pthread_once() implementation and tests
there is still a TODO on an init race condition

applied patch by kaliber

I needed Pthread condition variables for WebKit, so I implemented
them. I have tested this with a simple test program I downloaded
from the internet. We get the same result as on Linux, so I think
this is good. I will test it more with WebKit later.

Our Pthreads implementation is still missing some stuff, but this
adds a good chunk.

* PTHREAD_MUTEX_INITIALIZER inits to NULL, pthread_mutex_lock now call pthread_mutex_init to support this PTHREAD_MUTEX_INITIALIZER
* pthread_key_create and pthread_key_delete now manages correctly a list of key/destructor
* pthread_create now uses a private thread function to add a "on_exit_thread" call for destructors
* pthread_join now returns B_OK in every case, and, as a joinable thread could already be gone, wait_for_thread would not find it

added posix thread specific data functions
added a pthread_detach skeleton


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17880 a95241bf-73f2-0310-859d-f6bbb57e9c96

added some pthread_* and pthread_attr_* naive functions
I mapped pthread_t to thread_id for simplicity


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17879 a95241bf-73f2-0310-859d-f6bbb57e9c96

removed struct _pthread* forward declarations, they're not needed
added some more posix definitions, though they might be never used in Haiku


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17184 a95241bf-73f2-0310-859d-f6bbb57e9c96

now match pthread_private.h declarations


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17178 a95241bf-73f2-0310-859d-f6bbb57e9c96

added some missing pthreads definitions


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@17177 a95241bf-73f2-0310-859d-f6bbb57e9c96

Made header C++ safe, added prototype for pthread_atfork().


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@9301 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added the public pthread header - right now, only support for mutex and
mutexattr is there, and the header reflects this.
