wip/socklog 2.1.0 NetBSD

socklog, in cooperation with the runit package, is a small and secure replacement for syslogd. There are three main features syslogd provides:

\* receiving syslog messages from an unix domain socket ("/dev/log")
and writing them to various files on disk depending on
facility, priority and/or simple pattern matching.
\* receiving syslog messages from an udp socket ("0.0.0.0:514")
and writing them to various files on disk depending on
facility, priority and/or simple pattern matching.
\* writing received syslog messages to an udp socket ("a.b.c.d:514")
