I agree that constructing a struct addrinfo instance is ugly. There is no API 
to do it 'officially'...

So what did I do for `--dns-cache-preload` ? I created 
`wget_tcp_dns_cache_add()` which takes name, ip and port... Just use it :-) 
(current master).

The trick I did internally is to call getaddrinfo() with AI_NUMERICSERV set in 
the hints. So no expensive DNS request is being made, and a addrinfo structure 
is still set up for me.
