We need to have the source and destination addresses in the connection. They were lying in the stream interface so let's move them. The flags SI_FL_FROM_SET and SI_FL_TO_SET have been moved as well. It's worth noting that tcp_connect_server() almost does not use the stream interface anymore except for a few flags. It has been identified that once we detach the connection from the SI, it will probably be needed to keep a copy of the server-side addresses in the SI just for logging purposes. This has not been implemented right now though.
