Yes, there used to be a bunch of seams and wrappers around the logging
code in lib/ but I think libipsecconf didn't ever really use it, unlike

I don't think addconn has anything. But most output caused by addconn
comes from whack/pluto, so it ends up being processed regularly.

that actually does appear in the logs. I have no idea about the
framework that does it though :)
