….8 (GH-17884)

Minor fix in documentation:

- `sys.__unraisablehook__` is new in version 3.8
- Optional `sep` and `bytes_per_sep` parameters for `bytearray.hex` is also supported in Python 3.8 (just like `bytes.hex`)

This allows clang to get rid of the dependency on libgcov.
When linking, GCC passes -lgcov while clang passes the path to libclang_rt.profile-$arch.a

Fix regression in fractions.Fraction if the numerator and/or the
denominator is an int subclass. The math.gcd() function is now
used to normalize the numerator and denominator. math.gcd() always
return a int type. Previously, the GCD type depended on numerator
and denominator.

Replace direct acccess to PyVarObject.ob_size with usage of
the Py_SET_SIZE() function.

Fix time.localtime() on 64-bit AIX to support years before 1902 and after 2038.

Add Py_SET_SIZE() function to set the size of an object.

Add Py_EnterRecursiveCall and Py_LeaveRecursiveCall functions to
python3.def.

Replace direct acccess to PyVarObject.ob_size with usage of the
Py_SIZE() macro.

Move listobject.h code surrounded by "#ifndef Py_LIMITED_API"
to a new Include/cpython/listobject.h header file.

Add cpython/ header files to Makefile.pre.in and pythoncore project
of PCbuild.

Add _PyList_CAST() macro.

Add Py_SET_TYPE() function to set the type of an object.

Replace direct access to PyObject.ob_type with Py_TYPE().

Replace direct access to PyObject.ob_type with Py_TYPE().

Replace direct access to PyObject.ob_type with Py_TYPE().

I forgot to do it in #18260.

Replace direct access to PyObject.ob_type with Py_TYPE().

Only define PyTypeObject type once.

Add a Py_SET_REFCNT() function to set the reference counter of an
object.

Replace direct acccess to PyObject.ob_refcnt with usage of the
Py_REFCNT() macro.

Some numerator types used (specifically NumPy) decides to not
return a Python boolean for the "a != b" operation. Using the equivalent
call to bool() guarantees a bool return also for such types.

* Add backcompat defines and move non-limited API declaration to cpython/

This partially reverts commit 2ff58a2
which added PyObject_CallNoArgs to the 3.9+ stable ABI. This should not
be done; there are enough other call APIs in the stable ABI to choose from.

* Adjust documentation

Mark all newly public functions as added in 3.9.
Add a note about the 3.8 provisional names.
Add notes on public API.

* Put PyObject_CallNoArgs back in the limited API

* Rename PyObject_FastCallDict to PyObject_VectorcallDict

_Py_AddToAllObjects() is used in bltinmodule.c and typeobject.c when
Py_TRACE_REFS is defined.

Fix Py_TRACE_REFS build.

Add a fast-path for UTF-8 encoding in PyUnicode_EncodeFSDefault()
and PyUnicode_DecodeFSDefaultAndSize().

Add _PyUnicode_FiniEncodings() helper function for _PyUnicode_Fini().

Replace "struct _typeobject" with PyTypeObject in object.h.

Convert PyType_HasFeature(), PyType_Check() and PyType_CheckExact()
macros to static inline functions.

In the limited C API, PyObject_INIT() and PyObject_INIT_VAR() are now
defined as aliases to PyObject_Init() and PyObject_InitVar() to make
their implementation opaque. It avoids to leak implementation details
in the limited C API.

Exclude the following functions from the limited C API, move them
from object.h to cpython/object.h:

* _Py_NewReference()
* _Py_ForgetReference()
* _PyTraceMalloc_NewReference()
* _Py_GetRefTotal()
