* Added automap.go stub * Fixed bad error handling * Handle header error from io.Copy() * d2client.ClientConnection renamed to ServerConnection Having two interfaces named ClientConnection in adjacent packages was a point of confusion for me. Renamed the client ClientConnection to ServerConnection since clients connect to servers and servers to clients. * Fix lint warnings in remote_client_connection.go * Tidying and lint warnings in remote_client_connection.go * Switch statement in remote_client_connection.go now has matching blocks. * RemoteClientConnection.serverListener refactor. The switch statement is still repetitive but now it's separate. I think we would need generics to make it smaller. * Receiver name change from l to r. * Comments and other adjustments. * Old commits * Fixed bad error handling * Cleaned up remote_client_connection.go * SendPacketToClient removed.
