Subject: [PATCH] Remove the fake MSP_stereo_rendering extension

I originally created it because I thought it might be useful with VR
headsets.  Now it's apparent that VR rendering is done with different
APIs and the left/right constants are useless.  The other values of the
RWbuffer enum weren't being used for anything either.
