	request.
	(print_stop_reason): In the SIGNAL_RECEIVED case, if we're not
	outputting to MI, and we got a TARGET_SIGNAL_0, print "# Stopped",
	instead of mentioning signal 0.

	* thread.c (set_stop_requested): New.

	* linux-nat.c (queued_waitpid): Rename to ...
	(queued_waitpid_1): ... this.  Add `peek' argument.  Handle it.
