    *	(Flive_window_p): New function.
    	(Qlive_window_p): New variable, to name it in type errors.
    	(syms_of_window): Defsubr Slive_window_p, init and staticpro
    	(decode_window): Use CHECK_LIVE_WINDOW instead of
    	CHECK_WINDOW; the only thing a user should be able to do to a dead
    	window is check its type.
    	(Fcoordinates_in_window_p, Fnext_window, Fprevious_window,
    	Fdelete_other_windows, Fselect_window, Fsplit_window,
    	Fscroll_other_window): Use CHECK_LIVE_WINDOW instead of
    	(Fdelete_window): If WINDOW is a deleted window, do nothing;
    	there's no harm in allowing people to delete deleted windows.
    	Delete all of WINDOW's subwindows, too.
    	(delete_all_subwindows): Set the buffer, vchild, and hchild of the
    	windows we delete all to nil.
    	* window.c (Fwindow_minibuffer_p): Make the WINDOW argument
    	optional, like all the other window-querying functions.
    	* window.c (Fpos_visible_in_window_p): Use decode_window to handle
    	the WINDOW argument, instead of writing out that function's code.
    	* window.c (check_frame_size): Don't define this extern; that
    	doesn't mean anything.
    	* window.c (Fdelete_window): Choose an alternative when we delete
    	any frame's selected window, not just when we delete the selected
    	frame's selected window.
