gh-116333: Relax error string text expectations in SSL-related tests (GH-116334)
* Relax error string text expectations in SSL-related tests

As suggested [here][1], this change relaxes the OpenSSL error string
text expectations in a number of tests. This was specifically done in
support of more easily building CPython [AWS-LC][2], but because AWS-LC
is a fork of [BoringSSL][3], it should increase compatibility with that
library as well.

In addition to the error string relaxations, we also add some guards
around the `tls-unique` channel binding being used with TLSv1.3, as that
feature (described in [RFC 6929][4]) is [not defined][5] for TLSv1.3.

gh-115754: Add Py_GetConstant() function (#116883)
Add Py_GetConstant() and Py_GetConstantBorrowed() functions.

In the limited C API version 3.13, getting Py_None, Py_False,
Py_True, Py_Ellipsis and Py_NotImplemented singletons is now
implemented as function calls at the stable ABI level to hide
implementation details. Getting these constants still return borrowed
references.

Add _testlimitedcapi/object.c and test_capi/test_object.py to test
Py_GetConstant() and Py_GetConstantBorrowed() functions.

gh-114314: ctypes: remove stgdict and switch to heap types (GH-116458)
Before this change, ctypes classes used a custom dict subclass, `StgDict`,
as their `tp_dict`. This acts like a regular dict but also includes extra information
about the type.

This replaces stgdict by `StgInfo`, a C struct on the type, accessed by
`PyObject_GetTypeData()` (PEP-697).
All usage of `StgDict` (mainly variables named `stgdict`, `dict`, `edict` etc.) is
converted to `StgInfo` (named `stginfo`, `info`, `einfo`, etc.).
Where the dict is actually used for class attributes (as a regular PyDict), it's now
called `attrdict`.

This change -- not overriding `tp_dict` -- is made to make me comfortable with
the next part of this PR: moving the initialization logic from `tp_new` to `tp_init`.

The `StgInfo` is set up in `__init__` of each class, with a guard that prevents
calling `__init__` more than once. Note that abstract classes (like `Array` or
`Structure`) are created using `PyType_FromMetaclass` and do not have
`__init__` called.
Previously, this was done in `__new__`, which also wasn't called for abstract
classes.
Since `__init__` can be called from Python code or skipped, there is a tested
guard to ensure `StgInfo` is initialized exactly once before it's used.

gh-113964: Don't prevent new threads until all non-daemon threads exit (#116677)
Starting in Python 3.12, we prevented calling fork() and starting new threads
during interpreter finalization (shutdown). This has led to a number of
regressions and flaky tests. We should not prevent starting new threads
(or `fork()`) until all non-daemon threads exit and finalization starts in
earnest.

This changes the checks to use `_PyInterpreterState_GetFinalizing(interp)`,
which is set immediately before terminating non-daemon threads.

gh-116957: configparser: Do post-process values after DuplicateOptionError (GH-116958)
If you catch DuplicateOptionError / DuplicateSectionError when reading a
config file (the intention is to skip invalid config files) and then
attempt to use the ConfigParser instance, any values it *had* read
successfully so far, were stored as a list instead of string! Later
`get` calls would raise "AttributeError: 'list' object has no attribute
'find'" from somewhere deep in the interpolation code.

a list of one empty string, fixing the expected invariant.

As indicated by `exec('')`, empty strings are valid Python
source code.

gh-114271: Fix race in `Thread.join()` (#114839)
There is a race between when `Thread._tstate_lock` is released[^1] in `Thread._wait_for_tstate_lock()`
and when `Thread._stop()` asserts[^2] that it is unlocked. Consider the following execution
involving threads A, B, and C:

1. A starts.
2. B joins A, blocking on its `_tstate_lock`.
3. C joins A, blocking on its `_tstate_lock`.
4. A finishes and releases its `_tstate_lock`.
5. B acquires A's `_tstate_lock` in `_wait_for_tstate_lock()`, releases it, but is swapped
   out before calling `_stop()`.
6. C is scheduled, acquires A's `_tstate_lock` in `_wait_for_tstate_lock()` but is swapped
   out before releasing it.
7. B is scheduled, calls `_stop()`, which asserts that A's `_tstate_lock` is not held.
   However, C holds it, so the assertion fails.

The race can be reproduced[^3] by inserting sleeps at the appropriate points in
the threading code. To do so, run the `repro_join_race.py` from the linked repo.

There are two main parts to this PR:

1. `_tstate_lock` is replaced with an event that is attached to `PyThreadState`.
   The event is set by the runtime prior to the thread being cleared (in the same
   place that `_tstate_lock` was released). `Thread.join()` blocks waiting for the
   event to be set.
2. `_PyInterpreterState_WaitForThreads()` provides the ability to wait for all
   non-daemon threads to exit. To do so, an `is_daemon` predicate was added to
   `PyThreadState`. This field is set each time a thread is created. `threading._shutdown()`
   now calls into `_PyInterpreterState_WaitForThreads()` instead of waiting on
   `_tstate_lock`s.

GH-116554: Relax list.sort()'s notion of "descending" runs (#116578)
* GH-116554: Relax list.sort()'s notion of "descending" run

Rewrote `count_run()` so that sub-runs of equal elements no longer end a descending run. Both ascending and descending runs can have arbitrarily many sub-runs of arbitrarily many equal elements now. This is tricky, because we only use ``<`` comparisons, so checking for equality doesn't come "for free". Surprisingly, it turned out there's a very cheap (one comparison) way to determine whether an ascending run consisted of all-equal elements. That sealed the deal.

In addition, after a descending run is reversed in-place, we now go on to see whether it can be extended by an ascending run that just happens to be adjacent. This succeeds in finding at least one additional element to append about half the time, and so appears to more than repay its cost (the savings come from getting to skip a binary search, when a short run is artificially forced to length MIINRUN later, for each new element `count_run()` can add to the initial run).

While these have been in the back of my mind for years, a question on StackOverflow pushed it to action:

https://stackoverflow.com/questions/78108792/

They were wondering why it took about 4x longer to sort a list like:

[999_999, 999_999, ..., 2, 2, 1, 1, 0, 0]

than "similar" lists. Of course that runs very much faster after this patch.

gh-116167: Allow disabling the GIL with `PYTHON_GIL=0` or `-X gil=0` (#116338)
In free-threaded builds, running with `PYTHON_GIL=0` will now disable the
GIL. Follow-up issues track work to re-enable the GIL when loading an
incompatible extension, and to disable the GIL by default.

In order to support re-enabling the GIL at runtime, all GIL-related data
structures are initialized as usual, and disabling the GIL simply sets a flag
that causes `take_gil()` and `drop_gil()` to return early.

gh-109653: Reduce import overhead of uuid module on Linux (#115160)
This follows in the footsteps of #21586
This speeds up import uuid by about 6ms on Linux.

Before:
```
λ hyperfine -w 4 "./python -c 'import uuid'"
Benchmark 1: ./python -c 'import uuid'
  Time (mean ± σ):      20.4 ms ±   0.4 ms    [User: 16.7 ms, System: 3.8 ms]
  Range (min … max):    19.6 ms …  21.8 ms    136 runs
```
After:
```
λ hyperfine -w 4 "./python -c 'import uuid'"
Benchmark 1: ./python -c 'import uuid'
  Time (mean ± σ):      14.5 ms ±   0.3 ms    [User: 11.5 ms, System: 3.2 ms]
  Range (min … max):    13.9 ms …  16.0 ms    175 runs

gh-107361: strengthen default SSL context flags (#112389)
This adds `VERIFY_X509_STRICT` to make the default
SSL context perform stricter (per RFC 5280) validation, as well
as `VERIFY_X509_PARTIAL_CHAIN` to enforce more standards-compliant
path-building behavior.

As part of this changeset, I had to tweak `make_ssl_certs.py`
slightly to emit 5280-conforming CA certs. This changeset includes
the regenerated certificates after that change.

gh-71052: Fix several Android build issues (#115955)
This change is part of the work on PEP-738: Adding Android as a 
supported platform.

* Remove the "1.0" suffix from libpython's filename on Android, which 
  would prevent Gradle from packaging it into an app. 
* Simplify the build command in the Makefile so that libpython always 
  gets given an SONAME with the `-Wl-h` argument, even if the SONAME is
  identical to the actual filename.
* Disable a number of functions on Android which can be compiled and 
  linked against, but always fail at runtime. As a result, the native
  _multiprocessing module is no longer built for Android.
* gh-115390 (bee7bb331) added some pre-determined results to the 
  configure script for things that can't be autodetected when
  cross-compiling; this change adds Android to these where appropriate.
* Add a couple more pre-determined results for Android, and making them 
  cover iOS as well. This means the --enable-ipv6 configure option will 
  no longer be required on either platform.

Instead of showing a dot for each iteration, show:

- number of leaks for 1-9
- 'X' if there are more leaks

This allows more rapid iteration: when bisecting, I don't need
to wait for the final report to see if the test still leaks.

Also, show the full result if there are any non-zero entries.
This shows negative entries, for the unfortunate cases where
a reference is created and cleaned up in different runs.

Test *failure* is still determined by the existing heuristic.

Raise `ValueError` if `with_stem('')` is called on a path with a file
extension. Paths may only have an empty stem if they also have an empty
suffix.

gh-114763: Protect lazy loading modules from attribute access races (GH-114781)
Setting the __class__ attribute of a lazy-loading module to ModuleType enables other threads to attempt to access attributes before the loading is complete. Now that is protected by a lock.

gh-88516: show file proxy icon in IDLE editor windows on macOS (#112894)
The platform standard on macOS is to show a proxy icon for open
files in the titlebar of Windows. Make sure IDLE matches this
behaviour.

Don't use both the long and short names in the window title.
The behaviour of other editors (such as Text Editor) is to show
only the short name with the proxy icon.

gh-111225: Link extension modules against libpython on Android (#115780)
Part of the work on PEP 738: Adding Android as a supported platform.

* Rename the LIBPYTHON variable to MODULE_LDFLAGS, to more accurately 
  reflect its purpose.
* Edit makesetup to use MODULE_LDFLAGS when linking extension modules.
* Edit the Makefile so that extension modules depend on libpython on 
  Android and Cygwin.
* Restore `-fPIC` on Android. It was removed several years ago with a 
  note that the toolchain used it automatically, but this is no longer
  the case. Omitting it causes all linker commands to fail with an error
  like `relocation R_AARCH64_ADR_PREL_PG_HI21 cannot be used against
  symbol '_Py_FalseStruct'; recompile with -fPIC`.

gh-96310: Fix a traceback in argparse when all options in a mutually exclusive group are suppressed (GH-96311)
Reproducer depends on terminal size - the traceback occurs when there's
an option long enough so the usage line doesn't fit the terminal width.
Option order is also important for reproducibility.

Excluding empty groups (with all options suppressed) from inserts
fixes the problem.

gh-104090: Add exit code to multiprocessing ResourceTracker (GH-115410)
This builds on https://github.com/python/cpython/pull/106807, which adds
a return code to ResourceTracker, to make future debugging easier.
Testing this “in situ” proved difficult, since the global ResourceTracker is
involved in test infrastructure. So, the tests here create a new instance and
feed it fake data.
