5193e44c40 1. Don't override underscore version of aio_suspend(), system(), 
wait(), waitpid() and usleep(), they are internal versions and
   should not be cancellation points.
2. Make wait3() as a cancellation point.
3. Move raise() and pause() into file thr_sig.c.
4. Add functions _sigsuspend, _sigwait, _sigtimedwait and _sigwaitinfo,
   remove SIGCANCEL bit in wait-set for those functions, the signal is
   used internally to implement thread cancellation.

2b1dbc0acb Caching scheduling policy and priority in userland, a critical but baddly 
written application is frequently changing thread priority for SCHED_OTHER
policy.

66d0fee031 - Use same priority range returned by kernel's sched_get_priority_min() 
and sched_get_priority_max() syscalls.
- Remove unused fields from structure pthread_attr.

7d0c23506c Do not check validity of timeout if a mutex can be acquired immediately. 
Completly drop recursive mutex in pthread_cond_wait and restore recursive
after resumption. Reorganize code to make gcc to generate better code.

8bff50a485 Simplify _get_curthread() and _tcb_ctor because libc and rtld now 
already allocate thread pointer space in tls block for initial thread.
Only i386 and amd64 have been done, others still have to be tested.

255936645e Remove priority mutex code because it does not work correctly, 
to make it work, turnstile like mechanism to support priority
propagating and other realtime scheduling options in kernel
should be available to userland mutex, for the moment, I just
want to make libthr be simple and efficient thread library.

e586a0042e Add some more pthread stubs so that librt can use them. 
The thread jump table has been resorted, so you need to
keep libc, libpthread, and libthr in sync.

3668a2e494 In preparation for a new malloc implementation: 
* Add posix_memalign().

  * Move calloc() from calloc.c to malloc.c.  Add a calloc() implementation in
    rtld-elf in order to make the loader happy (even though calloc() isn't
    used in rtld-elf).

  * Add _malloc_prefork() and _malloc_postfork(), and use them instead of
    directly manipulating __malloc_lock.
