	* alloc.c, frame.c, frame.h, indent.c, keyboard.c, keyboard.h,
	lisp.h, term.c, termhooks.h, window.c, window.h, xdisp.c, xfns.c,
	xterm.c, xterm.h: Terminology changed.

        Don't generate switch-frame events by checking Vlast_event_frame;
	use a separate variable for that bookkeeping.  In order to
	generate them properly, we may need to fiddle with it.
	* keyboard.c (internal_last_event_frame): New variable.
	(command_loop_1): Check internal_last_event_frame, not
	Vlast_event_frame.
	(read_char, kbd_buffer_store_event): Set both Vlast_event_frame and
	internal_last_event_frame.
	(kbd_buffer_get_event): Check internal_last_event_frame to decide
	whether to generate a switch-frame event.  Set Vlast_event_frame
	after each event.
	(init_keyboard): Initialize both Vlast_event_frame and
	internal_last_event_frame.
	* keyboard.h (internal_last_event_frame): Add extern declaration
	for this.
	* frame.c (Vlast_event_frame): Remove external declaration for
	this.
	(Fselect_frame): Set internal_last_event_frame to Qnil to force a
	switch-frame event, not Vlast_event_frame; the latter is supposed
	to convey information to the user.
