Subject: [PATCH] [wayland] AbstractBackend indicates whether outputs are
 enabled

By default Outputs are considered to be enabled. This allows a
concrete backend implementation to mark outputs as disabled (e.g.
if dpms has put outputs into powersaving mode). This allows the
Compositor to disable itself if outputs are not visible anyway.
