    Dialog: Deprecates some methods and fix the build with --warnings=fatal
    
    * dialog.[hg|ccg]: Deprcate set_alternative_button_order_from_array(),
      alternative_button_order() (which have no deprecation advice in
      GTK+, but I have given up filing bugs about that) and
      get_action_area() (which does).
