	* defs.h: Mention ptid_is_pid.
	* inferior.h (ptid_is_pid): Declare.
	* gdbthread.h (struct thread_info) <stop_requested>: New field.
	(set_stop_requested): Declare.
	* infcmd.c (interrupt_target_1): Call set_stop_requested.
	* infrun.c (clear_proceed_status): Clear stop_requested.
	(infrun_thread_stop_requested_callback,
	infrun_thread_stop_requested): New.
	(handle_inferior_event): If a TARGET_SIGNAL_TRAP is reported on a
	thread that had an explicit stop request, pretend we got a
	TARGET_SIGNAL_0.  Always stop if the thread had an explicit stop
	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.
	(ptid_is_pid): New.
	* thread.c (set_stop_requested): New.

	* linux-nat.c (queued_waitpid): Rename to ...
	(queued_waitpid_1): ... this.  Add `peek' argument.  Handle it.
	(queued_waitpid): New, as wrapper to queued_waitpid_1.
	(push_waitpid): Push the SIGTRAP to the local event queue, to the
	kernel's.
	(send_sigint_callback): Delete.
	(linux_nat_stop_lwp): New.
	(linux_nat_stop): Use it.
