Modified files:
lib/libpthread/thread thr_create.c thr_find_thread.c
thr_kern.c thr_private.h thr_sig.c
Log:
1. Move thread list flags into new separate member, and atomically
put DEAD thread on GC list, this closes a race between pthread_join
and thr_cleanup.
2. Introduce a mutex to protect tcb initialization, tls allocation and
deallocation code in rtld seems no lock protection or it is broken,
under stress testing, memory is corrupted.
