Detailed Description

Direct UDP hole-punch assist for global joins.

While the client connects, it periodically re-sends a directory PunchRequest from THIS session's game socket. That makes the directory record the game socket's NAT mapping (not the throwaway helper socket used to discover the server) and re-notify the host, so the host punches back to the port we actually game on. Without this, port-restricted / symmetric NATs have no pinhole for our ConnectionRequest and the join times out. The request bytes are an opaque pre-encoded directory-control envelope so the transport stays agnostic of the discovery wire format.
