bpo-34572: change _pickle unpickling to use import rather than retrieving from sys.modules (GH-9047) (GH-11921)
Fix C implementation of pickle.loads to use importlib's locking mechanisms, and thereby avoid using partially-loaded modules.

bpo-35942: Improve the error message if __fspath__ returns invalid types in path_converter (GH-11831)
The error message emitted when returning invalid types from __fspath__ in interfaces that allow passing PathLike objects has been improved and now it does explain the origin of the error.

bpo-35992: Use PySequence_GetItem only if sq_item is not NULL (GH-11857)
Not using `__class_getitem__()` fallback if there is a non-subcriptable metaclass was caused by a certain asymmetry between how `PySequenceMethods` and `PyMappingMethods` are used in `PyObject_GetItem`. This PR removes this asymmetry. No tests failed, so I assume it was not intentional.

bpo-35931: Gracefully handle SyntaxError in pdb debug command (GH-11782)
Previously, `debug print(` would cause the interpreter to exit on a SyntaxError whereas `print(` would properly display the error and return to the pdb prompt.
This patch fixes this by pre-compiling the code before passing it to `Pdb.run`.

bpo-35633: test_lockf() fails with "PermissionError: [Errno 13] Permission denied" on AIX (GH-11424)
[bpo-35633](https://bugs.python.org/issue35633): Fix a test regression introduced with [bpo-35189](https://bugs.python.org/issue35189) (PEP 475: fnctl functions are not retried if interrupted (EINTR)).
Not only a blocking IO error needs to be ignored - permission errors also need to be ignored.
p.s. - iirc as a "test" only correction a NEWS item is not required. If this is not correct - just mention, and I'll add a NEWS blurb.
bpo-35961: Fix a crash in slice_richcompare() (GH-11830)
Fix a crash in slice_richcompare(): use strong references rather than
stolen references for the two temporary internal tuples.
The crash (or assertion error) occurred if a garbage collection
occurred during slice_richcompare(), especially while calling
PyObject_RichCompare(t1, t2, op).

bpo-1104: msilib.SummaryInfo.GetProperty() truncates the string by one character (GH-4517)
Add one char to MsiSummaryInfoGetProperty() output
Based on the patch in bpo-1104 by Anthony Tuininga (atuining) and Mark McMahon (markm).
(cherry picked from commit 2de576e16d42ce43698d384d0dd46ba6cf165424)
The previous wording could be read as saying that universal
newlines mode itself was deprecated, when it's only the 'U'
character in the mode field that should be avoided.
The update also moves the description of the 'U' mode character
out of the mode table, as the longer explanation was overly
intrusive as a table entry and overshadowed the actually useful
mode characters.

buffer of wchar_t is overriden and the previously allocated memory
is never freed.

Fix sparse file tests of test_tarfile on ppc64le with the tmpfs
filesystem.
Fix the function testing if the filesystem supports sparse files:
create a file which contains data and "holes", instead of creating a
file which contains no data.
tmpfs effective block size is a page size (tmpfs lives in the page
cache). RHEL uses 64 KiB pages on aarch64, ppc64 and ppc64le, only
s390x and x86_64 use 4 KiB pages, whereas the test punch holes of
4 KiB.
It previously deleted Window => Zoom Height by mistake.
(Zoom Height is now on the Options menu). On Mac, the settings
dialog is accessed via Preferences on the IDLE menu.

bpo-35486: Note Py3.6 import system API requirement change (GH-11540)
While the introduction of ModuleNotFoundError was fully backwards

forward compatible with clients that start relying on the new subclass.

* IocpProactor: prevent modification if closed (GH-11494)
* _wait_for_handle(), _register() and _unregister() methods of
IocpProactor now raise an exception if closed
* Add "closed" to IocpProactor.__repr__()
* Simplify IocpProactor.close()
IocpProactor.close() now uses time to decide when to log: wait 1
second before the first log, then log every second. Log also the
number of seconds since close() was called.
Previously, calling the strftime() method on a datetime object with a
trailing '%' in the format string would result in an exception. However,
this only occured when the datetime C module was being used; the python
implementation did not match this behavior. Datetime is now PEP-399
compliant, and will not throw an exception on a trailing '%'.

Fix memory leaks in asyncio ProactorEventLoop on overlapped operation
failures.
Changes:
* Implement the tp_traverse slot in the _overlapped.Overlapped type
to help to break reference cycles and identify referrers in the
garbage collector.
* Always clear overlapped on failure: not only set type to
TYPE_NOT_STARTED, but release also resources.
