 // Crypto handshake messages in QUIC take place over a reserved
 // reliable stream with the id 1.  Each endpoint (client and server)
 // will allocate an instance of a subclass of QuicCryptoStream
 // to send and receive handshake messages.  (In the normal 1-RTT
 // handshake, the client will send a client hello, CHLO, message.
 // The server will receive this message and respond with a server
 // hello message, SHLO.  At this point both sides will have established
 // a crypto context they can use to send encrypted messages.
