As reported in my earlier mail, this doesn't work if you have
other daemons (like NSD) using port 53 on the same box.
I know there are workarounds to achieve the same result,
but I would actually prefer a fix to unbound which removes the need
for workarounds. It's not like this is an overly complicated patch.
This probably should be an optional feature, but listen_dnsports.c
passes options via function arguments so doing this would make the patch
a lot bigger and obscure the core requested feature.
