I think we can just put static functions into npy_3kcompat.h. They're
anyway going to be short.

No objection here. I don't see any other way to deal with the destructor
issue.

The pickled arrays are, IIRC, only backward compatible, so that Py2
pickles can be opened with Py3, but not vice versa. This is because of
the str versus unicode issue.
