Reverse DNS Lookup for client IPs

Ralf Hildebrandt
I have to chime in on the "Reverse DNS Lookup for client IPs" thread
back in Feb 2016. I tried redefining the logging format for
url_rewrite_extras and store_id_extras in the config, but that
wouldn't work.

I had to change the file src/cf.data.pre and recompiled, after that
the number of reverse lookups dropped considerably.
