The implementation of __sizeof__() methods using _PyObject_SIZE() now use unsigned size_t type to compute the size, rather than the signed Py_ssize_t type. Cast explicitly signed (Py_ssize_t) values to unsigned type (Py_ssize_t).

Doesn't it need an explicit cast to size_t?

I chose to limit this change only to prepare the code for _PyObject_SIZE() API change.
With commit 131801d, _PyObject_SIZE() return type is now well defined: it returns a size_t.
