        (file_chooser_widget_default_realized_size_changed): Split
        function into realized and unrealized variants, and consolidate

        * gtk/gtkfilechooserembed.[ch] (gtk_file_chooser_embed_class_init):
        remove resizable-hints-changed, as it just complicated things.

        * gtk/gtkfilechooserdefault.c (update_appearance): Don't emit
        resizable-hints-changed.
