// SRS_SIGNAL_GRACEFULLY_QUIT, the SIGTERM, dispose then quit.
// SRS_SIGNAL_FAST_QUIT, the SIGTERM, do essential dispose then quit.
// SRS_SIGNAL_GRACEFULLY_QUIT, the SIGQUIT, do careful dispose then quit.
// SRS_SIGNAL_REOPEN_LOG, the SIGUSR1, reopen the log file.
// SRS_SIGNAL_RELOAD, the SIGHUP, reload the config.
// SRS_SIGNAL_PERSISTENCE_CONFIG, application level signal, persistence config to file.
// @remark, for SIGINT:
// no gmc, directly exit.
// no gmc, fast quit, do essential dispose then quit.
// for gmc, set the variable signal_gmc_stop, the cycle will return and cleanup for gmc.
// @remark, maybe the HTTP RAW API will trigger the on_signal() also.
