realip: chains of trusted proxies and IPv6 support. The module now supports recursive search of client address through the chain of trusted proxies, controlled by the "real_ip_recursive" directive (closes #2). It also gets full IPv6 support (closes #44) and canonical value of the $client_addr variable on address change. Example: real_ip_header X-Forwarded-For; set_real_ip_from 127.0.0.0/8; set_real_ip_from ::1; set_real_ip_from unix:; real_ip_recursive on;
