gh-125667: Statically Initialize the Arg Converter Data Values in _interpqueuesmodule.c (gh-125668)
(cherry picked from commit 7cf2dbc3cb)
Co-authored-by: Eric Snow <ericsnowcurrently@gmail.com>
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.

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`.

Returns a tuple of up to 100 strings for ALT_DIGITS lookup (an empty tuple on most locales).
Previously it returned the first item of that tuple or an empty string.

memcopy'ing arbitrary values to _Bool variable triggers undefined
behaviour. Avoid this.
We assume that `false` is represented by all zero bytes.

gh-120378: Fix crash caused by integer overflow in `curses` (GH-124555)
This is actually an upstream problem in curses, and has been reported
to them already:
https://lists.gnu.org/archive/html/bug-ncurses/2024-09/msg00101.html
This is a nice workaround in the meantime to prevent the segfault.

Switch more _Py_IsImmortal(...) assertions to _Py_IsImmortalLoose(...)
The remaining calls to _Py_IsImmortal are in free-threaded-only code,
initialization of core objects, tests, and guards that fall back to
code that works with mortal objects.

gh-123431: Harmonize extension code checks in pickle (GH-123434)
This checks are redundant in normal circumstances and can only work if
the extension registry was intentionally broken.
* The Python implementation now raises exception for the extension code
with false boolean value.
* Simplify the C code. RuntimeError is now raised in explicit checks.
