	* infrun.c (handle_inferior_event): When thread hoping, switch
	inferior_ptid to the event thread before removing breakpoints from
	the target.  If not stopping, also try to revert back to a thread
	that was doing a "next".  Check if that thread still exists before
	resuming.
	(currently_stepping_thread): Delete and merge with ...
	(currently_stepping): ... this.
	(currently_stepping_callback): Rename to ...
	(currently_stepping_or_nexting_callback): ... this, and also
	return true if the thread was stepping over a call (has a
	step-resume breakpoint).
