*
* However, when actually printing to syslog, we don't want to print messages

*
* In other words: NetworkManager has 3 levels that should not require highlighting:
* LOGL_INFO, LOGL_DEBUG, LOGL_TRACE. syslog on the other hand has only LOG_INFO and LOG_DEBUG.
*
* So, coerce those values before printing to syslog. When you receive the syslog_level
* from NetworkManager, instead of calling
* syslog(syslog_level, ...)
* you should call
* syslog(nm_utils_syslog_coerce_from_nm(syslog_level), ...)
