The CPython code base was written for the old "structmember.h" API with names like READONLY and T_INT. I propose to upgrade the code base to new public names like Py_READONLY and Py_T_INT.

#include "structmember.h" should be removed, but #include <stddef.h> should maybe be added in exchange to get the standard offsetof() function.
