 * \param logger_id An ID used to distinguish this logger from others

 *
 * \param name An informational name for this logger. Used for
 *     debugging.
 *
 * \param alproto The application layer protocol this logger is for,
 *     for example ALPROTO_DNS.
 *
 * \param LogFunc A pointer to the logging function.
 *
 * \param initdata Initialization data that will be provided to the
 *     ThreadInit callback.
 *
 * \param tc_log_progress The to_client progress state required for
 *     the log function to be called.
 *
 * \param ts_log_progress The to_server progress state required for
 *     the log function to be called.
 *
 * \param LogCondition A pointer to a function that will be called
 *     before the log function to test if the log function should be
 *     called.
 *
 * \param ThreadInitFunc Callback a thread initialization function,
 *     initdata will be provided.
 *
 * \param ThreadDeinitFunc Callback to a thread de-initialization
 *     function for cleanup.
