__GLXcontext. Drop all #includes of glcontextmodes.h and glcore.h.
Drop the DRI context modes extension.

prerequisite for glXCreateWindow().
Add getter for Mesa provider.
Export this for Xgl.
Move resource tracking out of drawable constructor to allow wrapping.

source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
