[PATCH xf86-video-amdgpu 0/3] Add RandR lease support [v2]

[Keith Packard]

When we last saw these patches, they required current X server bits to build,
while the project requires that the driver build back to X server 1.13. I've
added suitable checks and wrapped the new code in #ifdefs now.

If I don't hear any complaints in a few days (given that we're at the boundary
of a weekend), I'll go ahead and push these.
