Branch is a bit stale but better than reinventing everything.

Part of the reason I didn't get much further on that is the question of
distributing the _headers_. It would be a bit awkward if glvnd provided
the library you link to but not the headers defining its interface -
though, I guess no more awkward than the current situation. At any rate
glvnd doesn't install any, and there's no way to generate <GL/gl.h>
from the Khronos scripts at the moment (it's assumed to be a platform
implementation detail, and the version in Mesa is just handcoded
history).
