	Changes to improve menu positioning on Xinerama (#108328):

	* gtk/gtkmenu.c (struct _GtkMenuPrivate): Add a menu_num field
	to store the monitor on which the menu is to be positioned.

	* gtk/gtkmenu.[hc] (gtk_menu_position): Store the monitor number
	in the GtkMenuPrivate struct and fetch the monitor geometry after
	calling the position_func, in case it has been changed.

	* gtk/gtkmenu.c (gtk_menu_set_monitor): New function
	to be used in GtkMenuPositionFunc implementations for setting
	the monitor_num field in GtkMenuPrivate.

	* gtk/gtkmenuitem.c (gtk_menu_item_position_menu): Call
	gtk_menu_set_monitor.
