d6c88c0f27 Refine thread suspension code, now thread suspension is a blockable 
operation, the caller is blocked util target threads are really
suspended, also avoid suspending a thread when it is holding a
critical lock.
Fix a bug in _thr_ref_delete which tests a never set flag.

45180066f9 1. Add SIGEV_THREAD notification for mq_notify. 
2. Reuse current timer code and abstract some common code to
   to support both timer and mqueue.

8d9e23fb51 1. Retire macro SCLASS, instead simply use language keyword and 
put variables in thr_init.c.
2. Hide all global symbols which won't be exported.

3e60ee73cb Follow the mistake in libpthread, the first version name in libpthread 
is LIBTHREAD_1_0, but really it should be LIBPTHREAD_1_0.
Fix it so libmap.conf works again (it was broken by recent versioning
code in rtld_elf).

ae161ac239 Fix name compatible problem with POSIX standard. the sigval_ptr and 
sigval_int really should be sival_ptr and sival_int.
Also sigev_notify_function accepts a union sigval value but not a
pointer.

185b13c547 Add code to handle timer_delete(). The timer wrapper code is completely 
rewritten, now timers created with same sigev_notify_attributes will
run in same thread, this allows user to organize which timers can
run in same thread to save some thread resource.
