applied patch from owen to implement GParamSpecUnichar.

Sat Mar 31 23:55:58 2001  Tim Janik  <timj@gtk.org>

        * gtype.h:
        * gparamspecs.[hc]: applied patch from owen to implement
        GParamSpecUnichar.

Fri Mar 30 07:34:02 2001  Tim Janik  <timj@gtk.org>

        * gtype.c (type_iface_retrive_holder_info_Wm):
        * gtypeplugin.c (g_type_plugin_complete_interface_info):
        * gtypemodule.c (g_type_module_complete_interface_info):
        change order of instance_type and interface_type so they match
        the g_type_add_interface_*() API.

        * gsignal.c (g_signal_emit_valist): always assign C return value
        location, people depending on unaltered return values after emissions
        that had no handlers to run need to use g_signal_emitv().

        * gtype.[hc] (g_type_query): new function to allow querying of
        class and object size (semantics like g_signal_query()).
        currently the implementation is better held conservative so as to
        only support types that are classed and static.
