	* linux-nat.h (enum resume_kind): New.
	(struct lwp_info) <last_resume_kind>: New field.
	* linux-nat.c (linux_child_follow_fork): Set last_resume_kind to
	resume_stop on the new lwp.
	(add_lwp): Set last_resume_kind as resume_continue by default.
	(lin_lwp_attach_lwp): Set last_resume_kind as resume_stop.
	(resume_lwp): New, factored out from resume_callback.  Also check
	for pending status in lp->waitstatus.
	(resume_callback): Reimplement.
	(resume_clear_callback): Set last_resume_kind as resume_stop.
	(resume_set_callback): Set last_resume_kind as resume_continue.
	(linux_nat_resume, linux_handle_extended_wait): Set
	last_resume_kind.
	(running_callback): Also check lp->waitstatus for pending events.
	(select_singlestep_lwp_callback): Check that lp->last_resume_kind
	is resume_step.
	(stop_and_resume_callback): Don't re-resume if the core wanted the
	lwp stopped.  Use resume_lwp instead of resume_callback.  Avoid
	using an invalidated pointer.
	(linux_nat_filter_event): Don't discard SIGSTOPs as delayed
	SIGSTOPs if the core wanted the LWP to stop.
	(linux_nat_wait_1) Don't consume a pending SIGSTOP if the core
	wanted the lwp to stop.  If the core wanted the lwp to stop, and
	the lwp stopped with a SIGSTOP, report a TARGET_SIGNAL_0 instead
	of TARGET_SIGNAL_STOP.
	(linux_nat_stop_lwp): Don't synchronously wait for the lwp to stop
	here.  Instead, signal the lwp, and set the last_resume_kind to
	resume_stop.
