For actual sharing of buffers with other drivers (ie. actual hardware) we'll need to pimp things out a bit better to deal w/ caching, multiple memory domains, etc. See thread:

But for the llvmpipe use-case this isn't a problem. Nor do we really need prime/dri3 (dri2 is sufficient). So until the other issues are sorted lets remove DRIVER_PRIME.
v2: also drop the dead code

Yeah I'm ok with this too, but it pretty much means vgem is a thing for llvmpipe only. And then abusing dumb buffers is imo ok too, since I don't care too much what kind of horrors drivers pull of internally.
Ugh. But llvmpipe + dumb buffer is much inferior to SHM. -Chris
