remoteMenu: Port to GtkMenuTrackerItem

Browse Source 
This pulls in new upstream API that Ryan will maintain, removing
code on our side.

Currently, our implementation of submenus will be gone, but this
will be fixed in a few commits.

/**
* SECTION:gtkmenutracker
* @Title: GtkMenuTracker
* @Short_description: A helper class for interpreting #GMenuModel
*
* #GtkMenuTracker is a simple object to ease implementations of #GMenuModel.
* Given a #GtkActionObservable (usually a #GActionMuxer) along with a
* #GMenuModel, it will tell you which menu items to create and where to place
* them. If a menu item is removed, it will tell you the position of the menu
* item to remove.
*
* Using #GtkMenuTracker is fairly simple. The only guarantee you must make
* to #GtkMenuTracker is that you must obey all insert signals and track the
* position of items that #GtkMenuTracker gives you. That is, #GtkMenuTracker
* expects positions of all the latter items to change when it calls your
* insertion callback with an early position, as it may ask you to remove
* an item with a readjusted position later.
*
* #GtkMenuTracker will give you a #GtkMenuTrackerItem in your callback. You
* must hold onto this object until a remove signal is emitted. This item
* represents a single menu item, which can be one of three classes: normal item,
* separator, or submenu.
*
* Certain properties on the #GtkMenuTrackerItem are mutable, and you must
* listen for changes in the item. For more details, see the documentation
* for #GtkMenuTrackerItem along with https://live.gnome.org/GApplication/GMenuModel.
*
* The idea of @with_separators is for special cases where menu models may
* be tracked in places where separators are not available, like in toplevel
* "File", "Edit" menu bars. Ignoring separator items is wrong, as #GtkMenuTracker
* expects the position to change, so we must tell #GtkMenuTracker to ignore
* separators itself.

/**
* SECTION:gtkmenutrackeritem
* @Title: GtkMenuTrackerItem
* @Short_description: Small helper for model menu items
*
* A #GtkMenuTrackerItem is a small helper class used by #GtkMenuTracker to
* represent menu items. It has one of three classes: normal item, separator,
* or submenu.
*
* If an item is one of the non-normal classes (submenu, separator), only the
* label of the item needs to be respected. Otherwise, all the properties
* of the item contribute to the item's appearance and state.
*
* Implementing the appearance of the menu item is up to toolkits, and certain
* toolkits may choose to ignore certain properties, like icon or accel. The
* role of the item determines its accessibility role, along with its
* decoration if the GtkMenuTrackerItem::toggled property is true. As an
* example, if the item has the role %GTK_MENU_TRACKER_ITEM_ROLE_CHECK and
* GtkMenuTrackerItem::toggled is %FALSE, its accessible role should be that of
* a check menu item, and no decoration should be drawn. But if
* GtkMenuTrackerItem::toggled is %TRUE, a checkmark should be drawn.
*
* All properties except for the two class-determining properties,
* GtkMenuTrackerItem::is-separator and GtkMenuTrackerItem::has-submenu are
* allowed to change, so listen to the notify signals to update your item's
* appearance. When using a GObject library, this can conveniently be done
* with g_object_bind_property() and #GBinding, and this is how this is
* implemented in GTK+; the appearance side is implemented in #GtkModelMenuItem.
*
* When an item is clicked, simply call gtk_menu_tracker_item_activated() in
* response. The #GtkMenuTrackerItem will take care of everything related to
* activating the item and will itself update the state of all items in
* response.
*
* Submenus are a special case of menu item. When an item is a submenu, you
* should create a submenu for it with gtk_menu_tracker_new_item_for_submenu(),
* and apply the same menu tracking logic you would for a toplevel menu.
* Applications using submenus may want to lazily build their submenus in
* response to the user clicking on it, as building a submenu may be expensive.
*
* Thus, the submenu has two special controls -- the submenu's visibility
* should be controlled by the GtkMenuTrackerItem::submenu-shown property,
* and if a user clicks on the submenu, do not immediately show the menu,
* but call gtk_menu_tracker_item_request_submenu_shown() and wait for the
* GtkMenuTrackerItem::submenu-shown property to update. If the user navigates,
* the application may want to be notified so it can cancel the expensive
* operation that it was using to build the submenu. Thus,
* gtk_menu_tracker_item_request_submenu_shown() takes a boolean parameter.
* Use %TRUE when the user wants to open the submenu, and %FALSE when the
* user wants to close the submenu.
