Initial dri forwarding big bricks.

Browse Source 
* hw/kdrive/ephyr/ephyrdriext.c: added this to implement a DRI extension
	  into Xephyr. Normally the DRI extension is only present in the
	  xfree86 server, but I have ported it to Xephyr. The extension calls
	  functions that declared/defined in ephyrdri.h ephyrdri.c that
	  forwards the DRI calls to the host X. It does not work yet, as this
	  entry is just to put the big bricks in place.
	* hw/kdrive/ephyr/ephyrdri.c,h: declaration & definition of the
	  DRI client API that would hit the hostX server.
	* hw/kdrive/ephyr/GL/internal/dri_interface.h: added this, otherwise
	  inclusion of /usr/include/X11/dri/xf86dri.h won't compile
