This is a force-commit for:

kern_sig.c	1.215
kern_thread.c	1.103
kern_exit.c	1.199
proc.h		1.302

Orignal code would suspend an already suspended thread,
if user presses ^Z while a threaded program is running. Also
there is a race between job control and thread_exit(),  the
new code tests job control requesting before thread exits,
in wait() syscall, be sure to check child process is fully
stopped, this avoids a later SIGCHILD and returns STOPPED
status twice for a threaded child proc. A thread_stopped()
function is added for common code in several places.
