SOCKS Proxy Support

There are five cvars that control it. They are only settable from the at init time (from the OS command line).

+set net_socksEnabled 1
+set net_socksServer
+set net_socksPort
+set net_socksUsername
+set net_socksPassword

Please note that you use the address (name or IP number) of the SOCKS server (firewall machine), NOT a Q3ATEST server. The port number defaults to 1080, you should not need to change this.

It supports no authentication and username/password authentication method (RFC-1929); it does NOT support GSS-API method (RFC-1961) authentication.
