Initial dri forwarding big bricks.
* 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
