#10 Smack port multiplexer

[Casey Schaufler]

Create an application that serves as a TCP port multiplexer for services that need to share a single port at multiple labels. It should provide a star labeled socket on the well known port and pass information through to an application service that runs at the label of the requesting process. It should also provide for a "wildcard" server to provide service to any requester for which there is not an explicit server defined.
