mesa: implement per-buffer color masking
This is part of the GL_EXT_draw_buffers2 extension and part of GL 3.0.
The ctx->Color.ColorMask field is now a 2-D array. Until drivers are
modified to support per-buffer color masking, they can just look at
the 0th color mask.
The new _mesa_ColorMaskIndexed() function will be called by
glColorMaskIndexedEXT() or glColorMaski().
