        Add a new PanelActionButton widget so we can
        generically do action buttons. Fixes #84740.

        * Makefile.am: remove logout.[ch] from the build
        and add panel-action-button.[ch]. Also generate
        enums from panel-action-button.h.

        * applet.[ch]: add support for a generic "action button"
        applet and convert old lock/logout buttons into one of
        these for backwards compat.

        * foobar-widget.c: (append_actions_menu): use action
        callback from panel-action-button.h and setup dnd
        for screenshot, run and search menu items. Remove
        "Show Desktop" menu item.

        * logout.[ch]: remove.

        * menu.c:
        (add_action_button_to_panel): impl.
        (make_add_submenu): add screenshot, run and search
        buttons.
        (create_desktop_menu), (create_root_menu): setup
        dnd for screenshot, run and search menu items.

        * panel.c: (drop_internal_applet): impl new dnd
        for action buttons.

        * xstuff.[ch]: (xstuff_show_desktop): remove.
