5470bb56fc Check if the PP mutex is recursive, if we have already locked it, place the 
mutex in right order sorted by priority ceiling.

74c751131b get LIBPTHREAD_ADAPTIVE_SPIN early, so it can be used for some global

d99f6dac14 - Remove variable _thr_scope_system, all threads are system scope. 
- Rename _thr_smp_cpus to boolean variable _thr_is_smp.
- Define CPU_SPINWAIT macro for each arch, only X86 supports it.

8a8178c010 Create inline function _thr_umutex_trylock2 to only try one atomic 
operation, if it is failed, we call syscall directly, this saves
one atomic operation per lock contention.

347126a2e2 Move checking for c_has_waiters into low level _thr_ucond_signal and 
_thr_ucond_broadcast, clear condition variable pointer in cancellation
info after returing from _thr_ucond_wait, since kernel has already
dropped the internal lock, so we don't need to unlock it in cancellation
handler again.

6f54e82927 If a thread was detached, return EINVAL instead, the error code 
is also returned by pthread_detach() if a thread was already
detached, the error code was already documented:

>    [EINVAL]	The implementation has detected that the value speci-
>		fied by thread does not refer to a joinable thread.

8af480aec1 - 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.

5656b5fafa 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.

8042f26d52 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.

9f7b8b0d3c 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.

8ab9d78b9d 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.

05c3a5eab4 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.
