539e7a7770 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.

00fb440c1a 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.

6839e793cf 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.

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.
