    GtkMenuTracker: don't specialise "submenu" link
    
    We have some API in GtkMenuTracker and GtkMenuTrackerItem that is
    specifically designed to deal with submenus.
    
    Generalise these APIs to take a 'link_name' parameter that we always
    give as G_MENU_SUBMENU for now.  In the future, this will allow creating
    trackers for other types of links, such as sections.
