This script adds geographic location data to notices for the “remote”
host in a connection. It does make the assumption that one of the
addresses in a connection is “local” and one is “remote” which is
probably a safe assumption to make in most cases. If both addresses
are remote, it will use the $src address.
Notice types which should have the “remote” location looked up.
If GeoIP support is not built in, this does nothing.
