If the client doesn't set a fullscreen handler, we can't go fullscreen and shouldn't advertise that in the window menu. The menu implementation is a little simplistic, so we just move the "Fullscreen" entry to the end of the list and don't count it if we don't want it in the menu. https://bugs.freedesktop.org/show_bug.cgi?id=47751 https://bugs.freedesktop.org/show_bug.cgi?id=48106
