Make the main (and only) entry-point to gtkmodelmenu.c the now-public
gtk_menu_shell_bind_model().
Move the convenience constructors (gtk_menu_new_from_model() and
gtk_menu_bar_new_from_model()) to their proper files.
Remove the private header file.
Simplify the code a bit by making the initial populate part of the
bind() call.

Add an API to GtkAccelLabel for hardcoding the accel key to be displayed
(ie: allowing us to bypass the GtkAccelGroup lookup).
Use that from the GMenuModel-based GtkMenu construction code instead of
passing around the accel group.
This makes accel labels work in bloatpad again.
This patch effectively removes any hope of automatic runtime accel
changes in GMenuModel-based menus without additional application
support but it leaves the door open for this to be supported again in
the future (if we decide that it's important).

If a section or submenu item has a "action-namespace" attribute, the
action names of the created GtkModelMenuItems will be prefixed with that
namespace. Namespaces can be cascaded.
Drop the explicit passing of GActionGroup into the GtkMenu(Bar)
constructors and operate from the action context instead.
With GtkMenuItem implementing GtkActionable, this turns out to be pretty
easy (and most of the code can be removed from GtkModelMenuItem,
including the GActionObserver implementation).
Right now, when we create a GtkModelMenu for a GMenuModel, we listen to
changes to the menu's attach-widget to detect when a toplevel
GtkApplicationWindow becomes available to fetch actions from it.
This unfortunately breaks this simple code:
GtkWidget *application_window = gtk_application_window_new();
GtkWidget *menu_button = gtk_menu_button_new();
GMenuModel *menu_model = get_menu_model();
gtk_menu_button_set_menu_model(menu_button, menu_model);
gtk_container_add(GTK_CONTAINER(application_window), menu_button);
Since GtkMenuButton creates a GtkModelMenu and sets itself as its attach
widget before it's added to a hierarchy containing a
GtkApplicationWindow.
Fix the bug by simply listening for changes in the window hierarchy, and
creating the menu model when the attach widget is added to an
application window.

Put this in a separate file and substantially refactor it.
Move handling of submenu creation into gtkmodelmenuitem where it
belongs.
Improve our handling of when to show separators or not.
