According to the GIO docs, sections can have labels too. We support
them by inserting a non reactive menu item at the beginning of the
section. This item is specially flagged to be ignored while processing
changed signals from the model (since it does not correspond to any
model item)

GMenuProxy has been replaced by GDBusMenuModel, and the object path
has been moved (now needs to be retrieved from the AppMenu GApplication
property).
Update the test to prefix each action with "app." as documented,
and use a GtkApplicationWindow instead of a plain GtkWindow.
Use the new GApplication support in ShellApp to create the application
menu. Supports plain (no state), boolean and double actions.
Includes a test application (as no other application uses GApplication
for actions)

GDBusActionGroup and GMenuProxy are new objects in GIO 2.32 that
help with accessing menus and actions of remote applications.
This patch makes it possible for the shell to associate an
application with a dbus name and from that a GMenu, that will
be shown as the application menu.
