The new `dns-get-srv` returns a *list* of srv-rr structs, rather than
zero or one. A general-purpose RR-lookup routine, `dns-lookup`, exists
but is not exported for now since its API needs work. See comments in
net/dns.rkt.
T&D for url-strings-branch which separates URL parsing from
url network actions.
