Add ancillary data mechanism to send fds to compositor.

Currently we are just attaching the fds to the object id.
In theory this is not a valid implementation, since if we
have more than MAX_FD file descriptors this will not work.
But since this wont be the case in basically all cases of
the wayland protocol, we can just ignore that for now.
