The last uses of the hostandport variable, besides being strdup'ed
before being split into host and port, is to fill the host header in the
git protocol and to test whether to proxy the request.
Instead of relying on parse_connect_url() to return a host:port string
that makes sense there, re-derive one from the host and port variables.
This will allow to refactor parse_connect_url() to return separate host
and port strings.
