    Monitor callback that is called during the file transmission to
    monitor the transmission process.  The `status' indicates the current
    monitoring process.  The `error' will indicate the error type
    if `status' is SILC_CLIENT_FILE_MONITOR_ERROR.  The `offset' is the
    currently transmitted amount of total `filesize'.  The `client_entry'
    indicates the remote client, and the transmission session ID is the
    `session_id'.  The filename being transmitted is indicated by the
    `filepath'.  The `conn' is NULL if the connection to remote client
    does not exist yet.
