        * gtk/gtkplug.c (gtk_plug_focus): Send the focus on
        to the parent when there was no focus widget before
        and no focus widget after - that is, when there are
        no focusable widgets. (#108678, help tracking it
        down from Padraig O'Briain, Federico Mena Quintero, )

        * gtk/gtkxembed.[ch]: Move various shared utilities
        for the XEMBED protocol eused by GtkPlug and GtkSocket
        here.

        * gtk/gtkxembed.[ch] gtkplug.c gtksocket.c: Implement
        a flag bit that is sent with focus mesages to indicate
        that the focus has wrapped around on the toplevel;
        use this bit to catch infinite loops when there is no
        focusable widget at ll in the entire toplevel.

        * tests/testsocket.c (child_read_watch): Remove an
        extraneous unref.

        * gtk/gtkplug.c gtk/gtksocket.c gtk/gtkxembed.h:
        Up XEMBED protocol version to 1, add logic for
        sending the right version in XEMBED_EMBEDDED_NOTIFY.

        * gtk/gtksocket.c (gtk_socket_add_window): Send
        the embedder window in the XEMBED_EMBEDDED_NOTIFY
        as the spec requires.
