So far this new module contains: * Display * OutputInterface Display manages the server socket and server event loop. In general it's the entry point to any part of the server. OutputInterface is the abstraction for the wl_output interface on server side. An OutputInterface is created through the Display. The auto tests for ConnectionThread and Output are adjusted to use the internal server instead of starting Weston. Especially the Output test could be extended to test much more as we have absolute control over the server now.
