 * RPC wire format
 *
 * Each message consists of:
 *
 *    Name    | Type                  | Description
 * -----------+-----------------------+------------------
 *    Length  | int                   | Total number of bytes in message _including_ length.
 *    Header  | remote_message_header | Control information about procedure call
 *    Payload | -                     | Variable payload data per procedure
 *
 * In header, the 'serial' field varies according to:
 *
 *  - type == REMOTE_CALL
 *      * serial is set by client, incrementing by 1 each time
 *
 *  - type == REMOTE_REPLY
 *      * serial matches that from the corresponding REMOTE_CALL
 *
 *  - type == REMOTE_MESSAGE
 *      * serial is always zero
 *
 *  - type == REMOTE_STREAM
 *      * serial matches that from the corresponding REMOTE_CALL
 *
 * and the 'status' field varies according to:
 *
 *  - type == REMOTE_CALL
 *     * REMOTE_OK always
 *
 *  - type == REMOTE_REPLY
 *     * REMOTE_OK if RPC finished successfully
 *     * REMOTE_ERROR if something failed
 *
 *  - type == REMOTE_MESSAGE
 *     * REMOTE_OK always
 *
 *  - type == REMOTE_STREAM
 *     * REMOTE_CONTINUE if more data is following
 *     * REMOTE_OK if stream is complete
 *     * REMOTE_ERROR if stream had an error
 *
 * Payload varies according to type and status:
 *
 *  - type == REMOTE_CALL
 *          XXX_args  for procedure
 *
 *  - type == REMOTE_REPLY
 *     * status == REMOTE_OK
 *          XXX_ret         for procedure
