Major cleanup of 3D invariant state, fixing hangs with rotation and render.exa

Now, the generic invariant state is always set while the X Server is active,
and happens automatically when the X Server grabs the DRI lock.  More 3D state
is moved to the generic code.

Then, the 3D consumers (video, rotation, render) set last_3d to their enum
entry, and can update their own invariant state when another consumer was
active.
