-/**
- * Abstract base class for SocketTunnelServer/Client connection.
- *
- * Connection binds a pair of net::StreamSocket (or alike) through
- * a data channel. SocketTunnel may handle up to kMaxConnectionCount
- * simultaneous connection (DevTools can keep ~10 connection;
- * other connections hang in unopened state; additional connections
- * could help to deal with data channel latency).
- *
- * Client should create net::StreamListenSocket (or logical equivalent)
- * and listen for incoming connection. When one comes it sends CLIENT_OPEN
- * packet to the server.
- *
- * Server transforms client's packet to calls of net::StreamSocket. On
- * CLIENT_OPEN it creates a socket and connects. If connection succeeds
- * it sends back SERVER_OPEN_ACK. If it fails it sends SERVER_CLOSE.
- *
- * After SERVER_OPEN_ACK server may send SERVER_CLOSE any time (if the socket
- * it connects to has closed on another side). If client closes the connection
- * sending CLIENT_CLOSE server acknowledges it by sending SERVER_CLOSE.
- * Client may reuse connection ID once it received SERVER_CLOSE (because
- * data channel is ordered and reliable).
