          5.3  Closing a Channel
        When a party will no longer send more data to a channel, it SHOULD
         send SSH_MSG_CHANNEL_EOF.

                  byte      SSH_MSG_CHANNEL_EOF
                  uint32    recipient_channel

        No explicit response is sent to this message.  However, the
         application may send EOF to whatever is at the other end of the
        channel.  Note that the channel remains open after this message, and
         more data may still be sent In the other direction.  This message
         does not consume window space and can be sent even if no window space
         is available.

           When either party wishes to terminate the channel, it sends
           SSH_MSG_CHANNEL_CLOSE.  Upon receiving this message, a party MUST
         send back a SSH_MSG_CHANNEL_CLOSE unless it has already sent this
         message for the channel.  The channel is considered closed for a
           party when it has both sent and received SSH_MSG_CHANNEL_CLOSE, and
         the party may then reuse the channel number.  A party MAY send
         SSH_MSG_CHANNEL_CLOSE without having sent or received
         SSH_MSG_CHANNEL_EOF.

                  byte      SSH_MSG_CHANNEL_CLOSE
                  uint32    recipient_channel

         This message does not consume window space and can be sent even if no
         window space is available.

         It is recommended that any data sent before this message is delivered
           to the actual destination, if possible.
