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.
