Prototype UI and window classes

It is difficult to do any useful testing on ui_window without a real
display_t. Without display, there is no window, without window no GC,
without GC no UI resource.

As a compromise, in case of unit test, create UI with display == NULL,
in which case create window with NULL dwindow and a dummy GC
(so we have valid UI resource).
