- just display the hostname:port of the proxy url, rather than the full url.
this prevents someone `shoulder surfing' a proxy username/password
in $http_proxy. [suggested by perry]
- compact verbose notes for http fetchs; now displays
(via host:port, with authorization, with proxy authorization)
with each component being optional.
(and a couple introduced with the ipv6 mods...)
- don't override host with the canonical name; this prevented fetches from
http/1.1 virtual hosts from working if the virtual host was a CNAME.

- call freeaddrinfo() if res was built with getaddrinfo()
