nv40: implement user clip planes
It turns out the user planes handed to the driver are already in clip space.
Hence, we no longer need to transform incoming vertices before computing the
clip distance, and no longer need to change the interface provided by
gallium. Yay :)
The clip state change handling could be better, but this works.
