Log:
[TCPIP]
- Fix binding to an unspecified port on a connect so that it works reliably by
asking the TCP library for a free port instead of assuming that one we have is
free
- Fix binding to an unspecified port on a listen which previously would result
in the address file not having information stored about the port number assigned
- Fix a nasty bug which resulted in us binding to an arbitrary port during a
connect even when the client wanted a specific port
- Revert the hack that partially fixed this before
