geoip: trusted proxies support and partial IPv6 support. The module now supports recursive search of client address through the chain of trusted proxies (closes #100), in the same scope as the geo module. Proxies are listed by the "geoip_proxy" directive, recursive search is enabled by the "geoip_proxy_recursive" directive. IPv6 is partially supported: proxies may be specified with IPv6 addresses. Example: geoip_country .../GeoIP.dat; geoip_proxy 127.0.0.1; geoip_proxy ::1; geoip_proxy 10.0.0.0/8; geoip_proxy_recursive on;
