[3.12] gh-102304: Fix Py_INCREF() stable ABI in debug mode (#104763) (#105352)
gh-102304: Fix Py_INCREF() stable ABI in debug mode (#104763)
When Python is built in debug mode (if the Py_REF_DEBUG macro is
defined), the Py_INCREF() and Py_DECREF() function are now always
implemented as opaque functions to avoid leaking implementation
details like the "_Py_RefTotal" variable or the
_Py_DecRefTotal_DO_NOT_USE_THIS() function.
* Remove _Py_IncRefTotal_DO_NOT_USE_THIS() and
_Py_DecRefTotal_DO_NOT_USE_THIS() from the stable ABI.
* Remove _Py_NegativeRefcount() from limited C API.
(cherry picked from commit 92022d8416d9e175800b65c4d71d4e4fb47adcb0)
