	* arch-utils.c (default_prepare_to_proceed)
	(generic_prepare_to_proceed): Added new functions.
	* arch-utils.h: New function declarations for
	default_prepare_to_proceed() and generic_prepare_to_proceed().
	* gdbarch.sh: Added PREPARE_TO_PROCEED.
	* gdbarch.c: Regenerated.
	* gdbarch.h: Regenerated.
	* inferior.h: Added get_last_target_status() declaration.
	* infrun.c (get_last_target_status): Added new function.
	(handle_inferior_event): Saves last pid and waitstatus, which will
	get returned by get_last_target_status().

	* hppa-tdep.c (prepare_to_proceed):  Added comment stating that
	prepare_to_proceed() is potentially redundant since
	default_prepare_to_proceed() has been added.
	* linux-thread.c (prepare_to_proceed): Ditto.
	* lin-lwp.c (prepare_to_proceed): Ditto.
	* m3-nat.c (prepare_to_proceed): Ditto.
