Of course, it doesn't need to be a strict split. But, where possible,
I think it is better to match the C side for the helpers, because they
are thin wrappers that need to be updated and maintained at the same
time as the C side.

In any case, I mentioned it especially because `cpumask.h` already
exists and because it avoids an extra `#include` as I mentioned.

Just in case: `cpumask.rs` already exists, i.e. we are not adding new
granularity (or what do you mean by "at the moment" otherwise?)
