[PATCH 4/6] connect: pass separate host and port to git_tcp_connect and git_proxy_connect

[Mike Hommey <mh@xxxxxxxxxxxx>]

Instead of having each of them (and their callees) take a host:port
string and call get_host_and_port on it on their own, rely on the
get_host_and_port that already happens in git_connect and pass down
the separate host and port strings we got out of it.

Note that in git_tcp_connect_sock, the port was set to "<none>" in a
case that never can happen, so that code path was removed.
