[gjs/wip/walters/632938-use-g-irepository-get-object-gtype-interfaces: 91/91] object: Use g_irepository_get_object_gtype_interfaces

[Philip Chimento <pchimento src gnome org>]

commit d6abc579d3d551b01bf2fd26909a3c8b3b899f09
Author: Colin Walters <walters verbum org>
Date:   Fri Oct 22 18:09:16 2010 -0400

    object: Use g_irepository_get_object_gtype_interfaces
    
    Push the logic for this down into libgirepository, where we
    can more easily cache/optimize it.
    
    [skip ci] - Won't compile until corresponding patch is merged into
    gobject-introspection.
    
    Closes #55
