added g_list_insert_before().

Sat Jun 30 23:14:32 2001  Tim Janik  <timj@gtk.org>

        * glib/glist.[hc]: added g_list_insert_before().

        * glib/gslist.c (g_slist_insert_before): provide an implementation,
        prototype was already present...

Sat Jun 30 11:07:00 2001  Tim Janik  <timj@gtk.org>

        * gobject.[hc]: provide weak_ref/weak_unref functions,
        invoked from ->dispose. renamed ->shutdown() to ->dispose(),
        provide "public" API entry here: g_object_run_dispose(), this
        fucntion should _only_ be called from object system implementations
        (e.g. gtkobject.c) if at all.

        * gtypemodule.c (g_type_module_dispose): s/shutdown/dispose/

        * gsignal.h: removed compat aliases.

        * gobject.c (g_object_connect): support data objects.
