gallium: implement clamping controls (ARB_color_buffer_float)
BTW this changes the gallium interface.
Some rather cosmetic changes by Marek.

mesa/st: expose ARB_color_buffer_float if unclamping is supported

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
We set IMAGE_CLAMP_BIT in the caller based on _ClampReadColor, where
the operation mandates it. (see the removed XXX comment. -Marek)
TODO: did I get the set of operations mandating it right?
