We enforce a rule that a response message must completely fill the buffer that's been allocated to hold it. However, if an error occurs, the payload is off limits, so we should allow a short message to convey an error result. Change gb_connection_recv_response() to require the right message size only if there's no error. One other thing: The arriving data is only being copied into the response buffer if the request was successful. That means the response message header is assumed to have been initialized. That isn't a valid assumption. So change it so that if an error is seen, the header portion of the message is copied into the response buffer--but only the header.
