The running loop holder cache variable was always set to NULL when
calling set_running_loop.
Now set_running_loop saves the newly created running loop holder in the
cache variable for faster access in get_running_loop.

Each interpreter now has its own dict free list:
* Move dict free lists into PyInterpreterState.
* Move PyDict_MAXFREELIST define to pycore_interp.h
* Add _Py_dict_state structure.
* Add tstate parameter to _PyDict_ClearFreeList() and _PyDict_Fini().
* In debug mode, ensure that the dict free lists are not used after
_PyDict_Fini() is called.
* Remove "#ifdef EXPERIMENTAL_ISOLATED_SUBINTERPRETERS".
There are a bunch of other fd: int uses in this file, I expect many if not
all of them would be better off using the fildes converter. This particular
one was flagged by Coverity as it presumably flags fpathconf as not accepting
negative fds. I'd expect the other fd's to have been flagged as well
otherwise.
I'm marking this one as skip news as it really is a no-op.
The PY_SSIZE_T_CLEAN macro must now be defined to use
PyArg_ParseTuple() and Py_BuildValue() "#" formats: "es#", "et#",
"s#", "u#", "y#", "z#", "U#" and "Z#". See the PEP 353.
Update _testcapi.test_buildvalue_issue38913().
The PyObject_INIT() and PyObject_INIT_VAR() macros become aliases to,
respectively, PyObject_Init() and PyObject_InitVar() functions.
Rename _PyObject_INIT() and _PyObject_INIT_VAR() static inline
functions to, respectively, _PyObject_Init() and _PyObject_InitVar(),
and move them to pycore_object.h. Remove their return value:
their return type becomes void.
The _datetime module is now built with the Py_BUILD_CORE_MODULE macro
defined.
Remove an outdated comment on _Py_tracemalloc_config.
On Windows, #include "pyerrors.h" no longer defines "snprintf" and
"vsnprintf" macros.
PyOS_snprintf() and PyOS_vsnprintf() should be used to get portable
behavior.
Replace snprintf() calls with PyOS_snprintf() and replace vsnprintf()
calls with PyOS_vsnprintf().
In GH-2866, _Py_Bit_Length() was added to pymath.h for lack of a better
location. GH-20518 added a more appropriate header file for bit utilities. It
also shows how to properly use intrinsics. This allows reconsidering bpo-29782.
* Move the function to the new header.
* Changed return type to match __builtin_clzl() and reviewed usage.
* Use intrinsics where available.
* Pick a fallback implementation suitable for inlining.
