/* SOCKS4 and SOCKS5 client implementation (partial). This is mostly aimed at the ssh proxy; hence
 * there is no support for authentication methods.
 *
 * Since the API is designed to be a plug-in replacement for 'connect' we don't use the DNS
 * lookup features (have the proxy server resolve hostnames) of SOCKS4a and SOCKS5.
