_Py_PrintReferenceAddresses,_Py_PrintReferences:

interpolate PY_FORMAT_SIZE_T for refcount display
instead of casting refcounts to long.

I understand that gcc on some boxes delivers
nuisance warnings about this, but if any new ones
appear because of this they'll get fixed by magic
when the others get fixed.
