	(linux_nat_lp_status_is_event): Delete.
	(stop_wait_callback): Only call save_sigtrap after storing the
	pending status.
	(status_callback): If the thread had been stopped for a breakpoint
	that has since been removed, discard the event and resume the LWP.
	(count_events_callback, select_event_lwp_callback): Use
	lwp_status_pending_p instead of linux_nat_lp_status_is_event.
