src/sys/sys: syslog.h
Log Message:
openlog(3): add LOG_PTRIM and LOG_NLOG log options.
syslog(3) is the one stop method of logging system events and diagnostics.
When debugging a daemon in the foreground on a terminal, each line is
prefixed with tag[pid]: which is very repetative and can take up valuable
screen estate.
LOG_PTRIM solves this by removing this prefix from stderr output.
There is also the case where the debugging could involve a dry-run and
syslog(3) calls would pollute the system log with incorrect data.
LOG_NLOG solves this by not writing the the system log, but allowing
LOG_PERROR to operate as before.
