I added a --socks4 option that works like the current --socks5 option but
instead use the socks4 protocol.

  server configured in the system, the ares_init() call fails and thus
  curl_easy_init() fails as well. This causes weird effects for people who use
  numerical IP addresses only.

an app can use to let libcurl only connect to a remote host and then extract
