dri: Add an image creation with modifiers
Modifiers will be obtained or guessed by the client and passed in during image creation/import. In guessing, a client might decide to simply pass along all known modifiers This requires bumping the DRIimage version. As of this patch, the modifiers aren't plumbed all the way down, this patch simply makes sure the interface level stuff is correct. v2: Don't allow usage + modifiers v3: Make NAND actually NAND. Bug introduced in v2. (Jason) v4: - s/obtains/obtained (Jason) - Pull out i965 imlemnentation into a later patch (Emil) Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Reviewed-by: Eric Engestrom <eric.engestrom@imgtec.com> (v1) Reviewed-by: Jason Ekstrand <jason@jlekstrand.net> Acked-by: Daniel Stone <daniels@collabora.com>
