	Remove grab_start_serial, which we expect to be an ancient attempt
	to workaround sloppy/mouse focus bugs that have since been
	correctly fixed.  May fix some race conditions.  May cause nasty
	bugs in sloppy/mouse focus modes.  We'll find out soon enough...
	See #304430.

	* src/display.c (event_callback):
	remove event->xany.serial >= display->grab_start_serial in several
	event callback handlers

	* src/display.[ch] (struct _MetaDisplay, meta_display_begin_grab_op):
	* src/keybindings.c (do_choose_window, handle_workspace_switch):
	* src/frames.c (meta_frames_button_press_event):
	* src/core.[ch] (meta_core_begin_grab_op):
	* src/window.c (meta_window_client_message, meta_window_begin_grab_op):
	don't require an event_serial to be passed to
	meta_display_begin_grab_op () and don't record it anymore.

	* src/ui.c (struct _EventFunc, filter_func,
	  meta_ui_get_last_event_serial)
	* src/core.h (meta_ui_get_last_event_serial):
	remove meta_ui_get_last_event_serial() function (don't ask me why
	it was declared in core.h) and the last_even_serial field of
	_EventFunc
