815d860c2f - When building world WITHOUT_LIBPTHREAD, link libthr to libpthread. 
- Don't build ngctl(8) and cached(8) if threading libs aren't built.
- Fix various issues in a cached(8) makefile.

add205129c Eliminate atomic operations in thread cancellation functions, it should 
reduce overheads of cancellation points.

e8a2970aaf Don't inherit THR_FLAGS_NEED_SUSPEND for child process, child process 
only has one thread, setting the flag can cause the thread to be
suspended and no another thread will resume it.

653013bedc o Make _thr_umutex_init a function. 
o Eliminate unused parameter for some functions.
o Convert type of first parameter to void * for _thr_umtx_wait
  and _thr_umtx_wake.

5ffd88a18e TLS fixes: 
o  The TLS pointer (r2) points 0x7000 after the *end* of the TCB.
o  _rtld_allocate_tls() gets a pointer to the current TCB, not the
   current TLS pointer.
o  _rtld_free_tls() gets the size of the TCB structure.

58fc7458af Use umutex APIs to implement pthread_mutex, member pp_mutexq is added 
into pthread structure to keep track of locked PTHREAD_PRIO_PROTECT mutex,
no real mutex code is changed, the mutex locking and unlocking code should
has same performance as before.

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.

66d0fee031 - Use same priority range returned by kernel's sched_get_priority_min() 
and sched_get_priority_max() syscalls.

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.
