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)
