Some rather cosmetic changes by Marek.

mesa/st: use unclamped colors
This assumes that Gallium is to be interpreted as given drivers the
responsibility to clamp these colors if necessary.

mesa, mesa/st: handle read color clamping properly

TODO: did I get the set of operations mandating it right?
