0d29c148eb Try to reduce total time needed for suspending all threads,

bc414752d3 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.

7a65760923 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).

8f0371f19d Fix name compatible problem with POSIX standard. the sigval_ptr and

53bbdf8646 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.
