zzogl: some experiences to EGL (on linux). It can be enabled with -DEGL_API=TRUE 

* EGL is the interface between the window and opengl. The purpose is to replace GLX/WGL in a crossplatform way.
  Unfortunately so far only opensource driver use it (need not yet released mesa 9.0)
* clean most of the legacy GSopen1 window management. Only keep a basic window for debug with replayer.
