Subject: 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.

Subject: gallium: give the screen priority when it comes to buffer allocations

allows the driver to overwrite buffer allocation, first step on the way
to making winsys interface internal to the drivers. state trackers and
the code above it will go through the screen
