[Bf-committers] Library updates for Blender 2.8

[Brecht Van Lommel]

I think it would be great to have all these libraries updated, especially
the ones with CVEs.

* Blosc: definitely need to upgrade one to fix GCC build issues
* clew/cuew: I wonder if we even need OpenCL/CUDA support in OpenSubdiv,
maybe OpenGL is enough..
* flexbison/schroendinger/lapack: seems fine to remove
* openjpeg: don't think there is a good reason to have it in extern/
anymore, would be happy to see patch to remove it from there

I guess most of these are relatively easy with a tweak to versions.cmake,
not sure how difficult it is on Linux.
