	Merged heavily modified patch from maemo-gtk which enables opening
	and closing submenus on click, and introduces some usability
	changes when gtk-touchscreen-mode is enabled (bug #128968):

	* gtk/gtkmenushell.c (struct GtkMenuShellPrivate): added boolean
	"activated_submenu" to indicate that the current mouse operation
	(click or drag) has opened a submenu.

	(gtk_menu_shell_button_press): pop up submenus without delay
	and record the fact in "activated_submenu".

	(gtk_menu_shell_button_release): if a submenu was explicitely
	opened, or not opened by this release's button_press, or enough
	time has passed since timeout-opening it, close the submenu here.

	(gtk_menu_shell_enter_notify): when entering a menu item with
	any mouse button pressed, open its submenu.

	(gtk_real_menu_shell_move_current): in touchsreen mode, close the
	submenu when moving the focus away from it via keyboard-navigation.

	* gtk/gtkmenuitem.[ch] (_gtk_menu_item_popup_submenu): added
	parameter "gboolean with_delay" so GtkMenuShell can control this
	for the different scenarios of submenu showing.

	(_gtk_menu_item_popdown_submenu): new function. also needed by
	GtkMenuShell for closing submenus on click.

	Renamed internal function gtk_menu_item_select_timeout() to
	gtk_menu_item_popup_timeout().

	(gtk_menu_item_real_popup_submenu): new utility function which
	does the actual popup and records the exact time of the popup when
	the menu was timeout-opened (using g_get_current_time()).

	(gtk_real_menu_item_select): don't add the popup timeout when in
	touchscreen mode.

	* gtk/gtkmenu.c (gtk_menu_popup): in touchscreen mode, select the
	first item of every opened menu.
