OpenSubdiv: Use BLI module math functions
It became rather annoying to have those functions duplicated.
Surely, it's not really nice it's actually a bad level call,
but similar thing is happening in OCIO and Cycles.
IMO, it's better than having functions re-implemented, and
have this solved with new OpenGL pipeline.
