  net: rename gitno_connection_data to git_net_url "Connection data" is an imprecise and largely incorrect name; these structures are actually parsed URLs. Provide a parser that takes a URL string and produces a URL structure (if it is valid). Separate the HTTP redirect handling logic from URL parsing, keeping a `gitno_connection_data_handle_redirect` whose only job is redirect handling logic and does not parse URLs itself.
