glx: Back DRI3 enablement out of the stable branch.

After more testing (everyone else trying to build the stack is having as
much trouble as I had, even after the problems I had were fixed), it
really feels like dri3 is not something we're ready to support in this
stable branch.  The .c/.h code will remain here to enable easier
cherry-picking from master, and everything stays on master so we can ship
a solid DRI3 in 3 months.
