There are no public 'exporter' objects, so don't allude to them in the function names. At the same time, we want to make it clear that these functions are D-Bus specific. The new APIs are g_action_group_dbus_export_start g_action_group_dbus_export_query g_action_group_dbus_export_stop g_menu_model_dbus_export_start g_menu_model_dbus_export_query g_menu_model_dbus_export_stop
