Folks, let me fix the the CYTHON_FALLTHROUGH the right way.
Additionally, I'll extend the Travis-CI build matrix with python 2/3
and a couple of xcode images.

But IMHO the new output looks way better and it is totally in line with the
new trend of using annotations and typing.

I would not say that mpi4py is a big project, but it is around 15K lines of
Cython code, and it is also ready for Cython 3. I'll update mpi4py
