        * glib.h:
        * gdataset.c: implemented g_datalist_* along the lines of g_dataset,
        but operates on an opaque gpointer *datalist; pointer, e.g. for the
        implementation of GtkObject named data.
        we cache a certain portion of the already freed data entries now, to
        gain a slight performance improve with data reallocation.

Thu Sep 17 06:34:22 1998  Tim Janik  <timj@gtk.org>

        * gmodule.h:
        * gmodule.c: implemented g_module_make_resident() which can be
        used to make modules resident.
        fixed a buglet about the optional "g_module_de_init" function in
        modules, which could get invoked twice on very obscure occasions.
