        * gdataset.c: new file, gdatasets implement the object data
        mechanism from GtkObject. a generic data pointer is associated with
        a certain location and a key id.

        * gtk/gtkobject.h:
        * gtk/gtkobject.c:
        (gtk_object_data_try_key):
        (gtk_object_data_force_id): these are now macros substituting the old
        functions. we just use the corresponding g_dataset_* functions for
        key->id associations. (this is to assure unique key<->id associations).
