* glib/dbus-gproxy.c (dbus_gproxy_manager_new): start implementing the proxy manager, didn't get very far. * dbus/dbus-bus.c (dbus_bus_add_match): new (dbus_bus_remove_match): new * glib/dbus-gproxy.c (dbus_gproxy_new_for_service): add a path_name argument; adjust the other not-yet-implemented gproxy constructors to be what I think they should be.
