3be5d73f3d Fix a logic bug I re-introduced in my patch I sent to Daniel 
that would cause the selected shared threading library to be
overwritten with its 32-bit version on amd64.

bf3a79274d Enable symbol versioning by default. Use WITHOUT_SYMVER to disable it. 
Warning, after symbol versioning is enabled, going back is not easy
(use WITHOUT_SYMVER at your own risk).

Change the default thread library to libthr.

There most likely still needs to be a version bump for at least the
thread libraries.  If necessary, this will happen later.

2dd85eafce If a thread who's name is being set is not the current thread, use macros 
THR_THREAD_LOCK and THR_THREAD_UNLOCK instead, this should fix wrong
lock level problem.

ca27871833 - 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.

26cbb63b3f 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.

fcda4340a4 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.
