servers and clients now both use zombies. Zombies are interface pointers, so that they retain info for demarshalling fds AND new_id args, which must be turned into other zombies. Demarshalling messages to zombies is handled by the same wl_connection_demarshal code used for messages to live objects. Server zombies are eventually reaped after moving through FIFO zombie ring, because there is no delete_id request in the protocol. Signed-off-by: Jonathan Leivent <jleivent@comcast.net>
