Accepted range for the bytes_per_sep argument of bytes.hex(),
bytearray.hex(), memoryview.hex(), and binascii.b2a_hex()
is now increased, so passing sys.maxsize and -sys.maxsize is now
valid.

Use the ABI slot in stdlib extension modules to enable running
a check of ABI version compatibility.
_tkinter, _tracemalloc and readline don't use the slots, hence they need
explicit handling.

Add special cases for classmethod and staticmethod descriptors in

avoids reference count contention on the bound method and underlying
callable. This improves scaling when calling classmethods and
staticmethods from multiple threads.
Also refactor method_vectorcall in classobject.c into a new _PyObject_VectorcallPrepend() helper so that it can be used by
PyObject_VectorcallMethod as well.
