Add socksx package which supports SOCKS 4/4a/5
Motivation: SOCKS 4 and 5 are very different protocols although they share the same name. It is not possible to incorporate the two protocol versions into a single package. Modifications: - Add a new package called 'socksx' to supercede 'socks' package. - Add SOCKS 4/4a support to the 'socksx' package Result: codec-socks now supports all SOCKS versions
