Wed Nov  1 03:36:54 2000  Tim Janik  <timj@gtk.org>

        * gobject.c (g_object_base_class_finalize): destroy all signals that
        the finalized obejct type introduced.

        * gsignal.c (g_signals_destroy): don't require itype to have
        signals.

        * gobject.c (g_object_do_finalize): make sure all signal handlers
        are destroyed.

        * gsignal.[hc]:
        (g_signal_handler_find): only match on non-0 masks.
        (g_signal_handlers_block_matched):
        (g_signal_handlers_unblock_matched):
        (g_signal_handlers_disconnect_matched): new functions to block/unblock
        or disconnect handlers in groups.
