        * gparamspecs.[ch]: Add a new GParamSpecOverride type
        that is a pointer to a different paramspec in a parent
        class or interface.

        * gparam.[ch]: Add g_paramspec_get_redirect_target()
        which follows GParamSpecOverride to the real property.
        Make g_param_spec_pool_list() hand redirections,
        properties on interfaces.

        * gobject.[ch] gobjectnotifyqueue.c: Add
        g_object_interface_install_property,
        g_object_interface_find_property,
        g_object_interface_list_properties(). Redirect virtually all
        publically exposed GParamSpec's to the redirect target if
        any. (->constructor is the exception.)
