* wxSocket fixes

* wxStream: - new inheritance, new stream buffer, nearly the same API for the
              end user
            - updated other streams consequently
* wxGTK: some change to make it compile on GTK 1.0 and GTK 1.1
* small changes on wxThread to prepare a more reentrant lib
* wxVariant works with wxStream too now
