Fix time.strftime(), the strftime() method and formatting of the
datetime classes datetime, date and time.
* Characters not encodable in the current locale are now acceptable in
the format string.
* Surrogate pairs and sequence of surrogatescape-encoded bytes are no
longer recombinated.
* Embedded null character no longer terminates the format string.
This fixes also gh-78662 and gh-124531.

[3.13] gh-123370: Fix the canvas not clearing after running turtledemo.clock (GH-123457)
Rewriting the day and date every tick somehow prevented them from being removed either by clicking STOP or loading another example. The solution is to rewrite them only when they change.

There was a deadlock when `ProcessPoolExecutor` shuts down at the same
time that a queueing thread handles an error processing a task.
Don't use `_shutdown_lock` to protect the `_ThreadWakeup` pipes -- use
an internal lock instead. This fixes the ordering deadlock where the
`ExecutorManagerThread` holds the `_shutdown_lock` and joins the
queueing thread, while the queueing thread is attempting to acquire the
`_shutdown_lock` while closing the `_ThreadWakeup`.

On Arm v5 it is not possible to get the thread ID via c13 register
hence the illegal instruction. The c13 register started to provide
thread ID since Arm v6K architecture variant. Other variants of
Arm v6 (T2, Z and base) don’t provide the thread ID via c13.
For the sake of simplicity we group v5 and v6 together and
consider that instructions for Arm v7 only.

Lock `ZoneInfoType` to protect accesses to `ZONEINFO_STRONG_CACHE`.
Refactor the `tp_new` handler to use Argument Clinic so that we can just
use `@critical_section` annotations on the relevant functions.
Also use `PyDict_SetDefaultRef` instead of `PyDict_SetDefault` when
inserting into the `TIMEDELTA_CACHE`.

This fixes a crash when running the PyO3 test suite on the free-threaded
build. The `qsbr` field is initialized after the `PyThreadState` is
added to the interpreter's linked list -- it might still be NULL.
Instead, we "steal" the queue of to-be-freed memory blocks. This is
always initialized (possibly empty) and protected by the stop the world
pause.

gh-125269: Use `AC_LINK_IF_ELSE` to detect if `-latomic` is needed (GH-125416)
We previously used `AC_RUN_IF_ELSE` with a short test program to detect
if `-latomic` is needed, but that requires choosing a specific default
value when cross-compiling because the test program is not run.
Some cross compilation targets like `wasm32-emscripten` do not support
`-latomic`, while other cross compilation targets, like
`arm-linux-gnueabi` require it.

`PurePath.__init__()` incorrectly uses the `_raw_paths` of a given
`PurePath` object with a different flavour, even though the procedure to
join path segments can differ between flavours.
This change makes the `_raw_paths`-enabled deferred joining apply _only_
when the path flavours match.

In some locales (like French or Hebrew) the full or abbreviated names of
the default month and weekday used in __calc_date_time can be part of
other name or constant part of the %c format. The month name can also
match %m with constant suffix (like in Japanese). So the code failed to
correctly distinguish formats %a, %A, %b, %B and %m.
Cycle all month and all days of the week to find the variable part
and distinguish %a from %A and %b from %B or %m.
Fixed locales for the following languges:
Arabic, Bislama, Breton, Bodo, Kashubian, Chuvash, Estonian, French, Irish,
Ge'ez, Gurajati, Manx Gaelic, Hebrew, Hindi, Chhattisgarhi, Haitian Kreyol,
Japanese, Kannada, Korean, Marathi, Malay, Norwegian, Nynorsk, Punjabi,
Rajasthani, Tok Pisin, Yoruba, Yue Chinese, Yau/Nungon and Chinese.

Moreover, the site module now respects -E and -I command line
options: ignore PYTHON_BASIC_REPL in this case.

- move the Py_Main documentation from the very high level API section
to the initialization and finalization section
- make it clear that it encapsulates a full Py_Initialize/Finalize
cycle of its own
- point out that exactly which settings will be read and applied
correctly when Py_Main is called after a separate runtime
initialization call is version dependent
- be explicit that Py_IsInitialized can be called prior to
initialization
- actually test that Py_IsInitialized can be called prior to
initialization
- flush stdout in the embedding tests that run code so it appears
in the expected order when running with "-vv"
- make "-vv" on the subinterpreter embedding tests less spammy

The term "free variable" has unfortunately become genuinely
ambiguous over the years (presumably due to the names of
some relevant code object instance attributes).
While we can't eliminate that ambiguity at this late date, we can
at least alert people to the potential ambiguity by describing
both the formal meaning of the term and the common
alternative use as a direct synonym for "closure variable".

Support the "pager" binary in _pyrepl (GH-122878)
Debian (and derivatives) provide a /usr/bin/pager binary, managed by the
alternatives system, that always points to an available pager utility.
Allow _pyrepl to use it, to follow system policy.
This is a very trivial change, from a patch that Debian has been
carrying since 2.7 era. Seems appropriate to upstream.
