Another round of glRead/DrawBuffer() clean-ups and simplifications.
Replaced ctx->Color._DriverDrawBuffer with swrast->CurrentBuffer.
Replaced ctx->Pixel._DriverReadBuffer with ctx->Pixel._ReadSrcMask.
swrast->Driver.SetBuffer() takes FRONT/BACK_LEFT/RIGHT_BIT values now.
Added tokens and code for GL_AUX buffers, for completeness.
