* Move Python/formatter_unicode.c to Objects/unicode_formatter.c.
* Move Objects/stringlib/localeutil.h content into
unicode_formatter.c. Remove localeutil.h.
* Move _PyUnicode_InsertThousandsGrouping() to unicode_formatter.c
and mark the function as static.
* Rename unicode_fill() to _PyUnicode_Fill() and export it in
pycore_unicodeobject.h.
* Move MAX_UNICODE to pycore_unicodeobject.h as _Py_MAX_UNICODE.
* gh-139116: tracemalloc: Detach thread state when acquiring tables_lock
This prevents a deadlock when:
- One thread is in `_PyTraceMalloc_Stop`, with `TABLES_LOCK` held, calling
`PyRefTracer_SetTracer` which wants to stop the world
- Another is thread in `PyTraceMalloc_Track`, just attached thread state, waiting
for `TABLES_LOCK`
Detaching the thread state while waiting for `TABLES_LOCK` allows
`PyRefTracer_SetTracer` to stop the world.

Functions that take timestamp or timeout arguments now accept any
real numbers (such as Decimal and Fraction), not only integers or floats,
although this does not improve precision.
In the _interpreters module, we use PyEval_EvalCode() to run Python code in another interpreter. However, when the process receives a KeyboardInterrupt, PyEval_EvalCode() will jump straight to finalization rather than returning. This prevents us from cleaning up and marking the thread as "not running main", which triggers an assertion in PyThreadState_Clear() on debug builds. Since everything else works as intended, remove that assertion.
During finalization, we need to mark all non-daemon threads as daemon to quickly shut down threads when sending CTRL^C to the process. This was a minor regression from GH-136004.
With https://github.com/llvm/llvm-project/pull/150201 being merged, there is
now a better way to generate the Emscripten trampoline, instead of including
hand-generated binary WASM content. Requires Emscripten 4.0.12.
There was a deadlock originally seen by Memray when a daemon thread
enabled or disabled profiling while the interpreter was shutting down.
I think this could also happen with garbage collection, but I haven't
seen that in practice.
The daemon thread could be hung while trying acquire the global rwmutex
that prevents overlapping global and per-interpreter stop-the-world events.
Since it already held the main interpreter's stop-the-world lock, it
also deadlocked the main thread, which is trying to perform interpreter
finalization.
Swap the order of lock acquisition to prevent this deadlock.
Additionally, refactor `_PyParkingLot_Park` so that the global buckets
hashtable is left in a clean state if the thread is hung in
`PyEval_AcquireThread`.
Remove dead code in code gen - codegen_check_annotation is only called if future annotations are enabled, and if future annotations are enabled it does nothing.
The codecs lookup function now performs only minimal normalization of
the encoding name before passing it to the search functions:
all ASCII letters are converted to lower case, spaces are replaced
with hyphens.
Excessive normalization broke third-party codecs providers, like
python-iconv.
Revert "bpo-37751: Fix codecs.lookup() normalization (GH-15092)"
This reverts commit 20f59fe1f7.
Follow-up refactoring after GH-133143, where we use `_Py_ID` for "big" and "little"
in `abi_info.byteorder`.
This uses `_Py_ID` for `sys.byteorder`, but also `float_repr_style` and a module name.
This makes information about the interpreter ABI more accessible.
