The MaxMind DB format is now recognized, with the fallback to the
legacy format (reached End-of-Life in May 2022). Migration requires
switching to MMDB database files:
geoip_country /usr/share/GeoIP/GeoLite2-Country.mmdb;
geoip_city /usr/share/GeoIP/GeoLite2-City.mmdb;
geoip_org /usr/share/GeoIP/GeoLite2-ASN.mmdb;
Either libmaxminddb or libGeoIP is sufficient to build the modules;
configure fails if neither is found.
Notes on the MMDB lookups:
*) $geoip_country_code3 and $geoip_city_country_code3 are converted from
the alpha-2 codes with a compiled-in ISO 3166-1 table, as the MMDB
databases provide alpha-2 codes only.
*) $geoip_org looks up "autonomous_system_organization", "isp",
"organization", and "domain" in turn, to match the legacy ASNum, ISP,
Org, and Domain database editions.
*) $geoip_area_code has no MMDB counterpart and is never found.
*) $geoip_region and $geoip_region_name come from subdivisions[0], and
thus may differ in value from the legacy ones.
*) $geoip_dma_code comes from location.metro_code, which is deprecated
by MaxMind and may be absent.
