Subject: [PATCH] Expose the udp/tcp listening socket w/ ListenAndServe()

Expose the udp and tcp listening socket when ListenAndServe() is used, it seems like
plopping them on Server.Listener and Server.PacketConn would be ideal. The use case is so
that a port of zero can be used and having them exposed will allow for examination of the port
that is bound.
