Create a version of listen() which handles common logic internally, including scanning for an available port number, and notifying what port was chosen. The port is managed internal to ListenSocket, so that the logic interacting with it doesn't need to manually manage a port number, and hence a port number does not need to exist for non AF_INET sockets.
