add some assertions

2002-03-06  Havoc Pennington  <hp@pobox.com>

	* src/core.c (meta_core_get_grab_frame): add some assertions

	* src/menu.c (meta_window_menu_new): make another warning
	into a verbose

	* src/display.c (meta_change_button_grab): use verbose rather than
	warning to log failures to grab button, since these are typically
	BadWindow from a destroyed window.
