AFAICS this function was added in OpenGL 3.1 and there is no specific
ARB extension for it. Maybe adding a new WINED3D_GL_ entry to flag the
availability of the function is a good idea.
Also you probably want to MAP_GL_FUNCTION() the NV variant to the core
one and add an entry for GL_ARB_ES3_compatibility to core_extensions.

Probably not, but nothing prevents you to use 0xffff for 16-bit
indices and force re-setting the restart index when changing between
16-bit and 32-bit indices.
