	* infrun.c (context_switch): New function.  Abstract the operation
	of saving and restoring infrun's state when switching threads.
	(handle_inferior_event): Normalize the handling of the 'thread hop'
	event (when the wrong thread hits a thread-specific breakpoint,
	and we need to solo-step that thread past the breakpoint).
	Call keep_going, instead of target_resume.  Handle the subsequent
	singlestep-trap as a normal event instead of just resuming.
