Please keep in mind that while these changes are working their way
upstream, i'll still need to move all of our OpenGL add-ons into Mesa as
well. Not quite sure how to build an add-on from within the Mesa build
system, but I guess I'll have to figure it out.

We're pretty much going to have to fork Mesa. Likely i'll set up a
github repo, tag 7.8.2, and apply all the needed patches.
