v2: do not break ABI, but instead introduce new entry point for
dma buffers and bump up the dri-interface version to eight
v3 (Chad): allow the hook to specify an error originating from the
driver. For now only unsupported format is considered.
I thought about rejecting the hints also as they are
addressing only YUV sampling which is not supported at
the moment but then thought against it as the spec is
not saying one way or the other.
v4 (Eric, Chad): restrict to rgb formatted only
v5: rebased on top of i915/i965 split
v6 (Chad): document using full extension name
