Modified Files:
	src/lib/libpthread: pthread.c pthread_sig.c

Log Message:
in pthread_kill() and pthread_suspend_np(), return without doing anything
if the target thread is a zombie.

in all the functions that didn't do so already, verify a pthread_t before
dereferencing it (under #ifdef ERRORCHECK, since these checks are not
mandated by the standard).

clean up some debugging stuff.
