Fix a leak and subsequent crash in parsetok.c caused by realloc misuse on a rare codepath.
Realloc returns a null pointer on failure, and then growable_comment_array_deallocate crashes later when it dereferences it.
Replace statically allocated types with heap allocated types:
use PyType_FromSpec().
Add a module state to store the _abc_data_type.
Add traverse, clear and free functions to the module.
Speed up calls to list() by using the PEP 590 vectorcall
calling convention. Patch by Mark Shannon.

Change 0/1 assignments to 'executing', 'canceled', 'reading', 'endoffile'.
These are not used outside of pyshell. Other bools already use False/True.
Add comment about int needed for Windows call.
Remove self.more, unused in idlelib and code.InteractiveInterpreter.
The latter uses 'more' as a local.
Remove daemon threads from :mod:`concurrent.futures` by adding
an internal `threading._register_atexit()`, which calls registered functions
prior to joining all non-daemon threads. This allows for compatibility
with subinterpreters, which don't support daemon threads.
If fork was not called by a thread spawned by threading.Thread,
threading._after_fork() now creates a _MainThread instance for
_main_thread, instead of a _DummyThread instance.
Replace statically allocated types with heap allocated types:
use PyType_FromSpec().
Add a module state to store the Scanner and Encoder types.
Add traverse, clear and free functions to the module.
Add _PySys_Audit() function to the internal C API: similar to
PySys_Audit(), but requires a mandatory tstate parameter.
Cleanup sys_audit_tstate() code: remove code path for NULL tstate,
since the function exits at entry if tstate is NULL. Remove also code
path for NULL tstate->interp: should_audit() now ensures that it is
not NULL (even if tstate->interp cannot be NULL in practice).
PySys_AddAuditHook() now checks if tstate is not NULL to decide if
tstate can be used or not, and tstate is set to NULL if the runtime
is not initialized yet.
Use _PySys_Audit() in sysmodule.c.
This pull request fixes the newline conversion bug originally reported in bpo-1812. When that issue was originally submitted, the open builtin did not default to universal newline mode; now it does, which makes the issue fix simpler, since the only code path that needs to be changed is the one in doctest._load_testfile where the file is loaded from a package whose loader has a get_data method.
_tracemalloc.c and _xxsubinterpretersmodule.c use
PyThreadState_GetFrame() and PyThreadState_GetInterpreter() to no
longer depend on the PyThreadState structure.
Update _asyncio, _bz2, _csv, _curses, _datetime,
_io, _operator, _pickle, _queue, blake2,
multibytecodec and overlapped C extension modules
to use PyModule_AddType().
Fix os.getgrouplist(): if getgrouplist() function fails because the
group list is too small, retry with a larger group list.
On failure, the glibc implementation of getgrouplist() sets ngroups
to the total number of groups. For other implementations, double the
group list size.
Remove two unused imports: _thread and _weakref. Avoid creating a new
winreg builtin module if it's already available in sys.modules.
The winreg module is now stored as "winreg" rather than "_winreg".
PyThreadState.frame is a borrowed reference, not a strong reference:
PyThreadState_Clear() must not call Py_CLEAR(tstate->frame).
Remove test_threading.test_warnings_at_exit(): we cannot warranty
that the Python thread state of daemon threads is cleared in a
reliable way during Python shutdown.
