        Based on a patch from Padraig O'Briain <padraig.obriain@sun.com>
        in bug #138535

        * panel-menu-button.c:
        (panel_menu_button_menu_detacher): remove workaround for bug #113112
        (panel_menu_button_create_menu): re-create the menu here if needs be.
        (panel_menu_button_accessible_*): add an AtkObject implementation
        so we can create the menu when get_n_children() is called.

        * panel-a11y.[ch]:
        (panel_a11y_get_is_a11y_enabled): rename from is_gail_loaded()
        and make public.
        (panel_a11y_query_accessible_parent_type): implement standard
        ugly hack to inherit from an object in gail without linking
        against gail.
