	Allow to pop up menus without grabbing the keyboard. Useful for
	stuff like virtual keyboards. Fixes bug #159890

	* gtk/gtk.symbols
	* gtk/gtkmenushell.[ch]: added boolean property "take-focus"
	and public API gtk_menu_shell_set/get_take_focus().

	* gtk/gtkmenu.c (gtk_menu_popup)
	(popup_grab_on_window): don't grab the keyboard if take_focus
	is FALSE.

	* gtk/gtkmenuitem.c (_gtk_menu_item_popup_submen): propagate the
	parent menu_shell's take_focus property to the submenu which is
	about to be popped up.

* If @take_focus is %TRUE (the default) the menu will take the keyboard focus
* so that it will receive all keyboard events which is needed to enable
* keyboard navigation in menus.
*
* Setting @take_focus to %FALSE is useful only for special applications
* like virtual keyboard implementations which should not take keyboard
* focus.
*
* The @take_focus state of a menu or menu bar is automatically propagated
* to submenus whenever a submenu is popped up, so you don't have to worry
* about recursively setting it for your entire menu hierarchy. Only when
* programmatically picking a submenu and popping it up manually, the
* @take_focus property of the submenu needs to be set explicitely.
*
* Note that setting it to %FALSE has side-effects:
*
* If the focus is in some other app, it keeps the focus and keynav in
* the menu doesn't work. Consequently, keynav on the menu will only
* work if the focus is on some toplevel owned by the onscreen keyboard.
*
* To avoid confusing the user, menus with @take_focus set to %FALSE
* should not display mnemonics or accelerators, since it cannot be
* guaranteed that they will work.
