Replace the geoip module with geo_maxmind, geoban, and geoclass.

MaxMind have EOL'd the library that the geoip module uses and have
replaced it with libmaxminddb.

The geoip module has been split into geo_maxmind which provides
geolocation data, geoban which provides location-based channel
bans, and geoclass which is used to filter a user into a connect
class based on location.
