Rob Clark 85f84ea148 gallium: add # of MRT to blend state

for unused MRTs.  Otherwise the driver would have to manage different
blend CSOs for different potential #s of render targets.

Brian Paul 702ff0b9a0 gallium/docs: document alpha_to_coverage and alpha_to_one blend state 
The gallium interface defines these like DX10.  Note that OpenGL ignores
these options if MSAA is disabled or the dest buffer doesn't support
MSAA.
