New function ngx_http_get_forwarded_addr() to look up real client address.

On input it takes an original address, string in the X-Forwarded-For format
and its length, list of trusted proxies, and a flag indicating to perform
the recursive search.  On output it returns NGX_OK and the "deepest" valid
address in a chain, or NGX_DECLINED.  It supports AF_INET and AF_INET6.
Additionally, original address and/or proxy may be specified as AF_UNIX.
