  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.
