Implement socket server code that properly handles async I/O, partial
messages, multiple messages per buffer and important things like
connection limits and file descriptor accounting. It works with TCP
connections as well as switch(4). The ofrelay.c part replaces
networking that was in ofp.c and will soon handle all socket
connections of switchd. It is called "ofrelay" because it will be
used as client, server, and forwarder.
