libdrm issues blocking accelerated indirect GL

It also lives in Mesa at src/mesa/drivers/dri/dri_client,

we really need to drop the copy in Mesa and use the one in the DRM for
building the -dri drivers,

I'm not sure what my opinion on the best way to move forward is, all
options look messy, as usual we always need to handle the old libGL/new
driver cases and new libGL/old driver, I'll think about it some more and
hopefully Ian or Keith voices some directional opinion :-)
