Merge of r5013: proxy: fixed proxy_method to always add space.

Before the patch if proxy_method was specified at http{} level the code
to add trailing space wasn't executed, resulting in incorrect requests
to upstream.

Merge of r5014, r5015, r5016, r5030: geoip ipv6 support.

*) Configure: fixed style of include directories.

*) Configure: fixed GeoIP library detection.

*) GeoIP: IPv6 support.  When using IPv6 databases, IPv4 addresses are
   looked up as IPv4-mapped IPv6 addresses.  Mostly based on a patch
   by Gregor Kališnik (ticket #250).

*) GeoIP: removed pseudo-support of "proxy" and "netspeed" databases.
