mesa: per-buffer blend enabled flags
ctx->Color.BlendEnabled is now a GLbitfield instead of a GLboolean to
indicate blend on/off status for each color/draw buffer.
This is infrastructure for GL_EXT_draw_buffers2 and OpenGL 3.x
New functions include _mesa_EnableIndexed(), _mesa_DisableIndexed(), and
_mesa_IsEnabledIndexed(). The enable function corresponds to
glEnableIndexedEXT() for GL_EXT_draw_buffers2 or glEnablei() for GL3.
Note that there's quite a few tests for ctx->Color.BlendEnabled != 0 in
drivers, etc. Those tests can remain as-is since the mask will be 0 or ~0
unless GL_EXT_draw_buffers2 is enabled.
