make thread killlock async-signal-safe for pthread_kill
pthread_kill is required to be AS-safe. that requirement can't be met if the target thread's killlock can be taken in contexts where application-installed signal handlers can run. block signals around use of this lock in all pthread_* functions which target a tid, and reorder blocking/unblocking of signals in pthread_exit so that they're blocked whenever the killlock is held.
