Change threxit() to take a pointer to a pid_t to zero out from the
kernel so that librthread can detect when a thread is completely
done with its stack without need a kqueue. The dying thread moves
itself to a GC list, other threads scan the GC list on pthread_create()
and pthread_join() and free the stack and handle once the thread's
thread id is zeroed.
