push an error trap around the whole window-key-grab loop

Browse Source 
2002-11-06  Havoc Pennington  <hp@pobox.com>

	* src/keybindings.c (grab_keys): push an error trap around the
	whole window-key-grab loop
	(ungrab_all_keys): avoid requiring return value from the error
	trap, unless in debugging mode
	(regrab_window_bindings, regrab_screen_bindings): push traps
	around the loops, for efficiency

	* src/display.c (event_callback): fix from Padraig O'Briain to
	compress extra MappingNotify events to avoid extra work.
