Move pathlib globbing implementation into a new private class: `glob._Globber`. This class implements fast string-based globbing. It's called by `pathlib.Path.glob()`, which then converts strings back to path objects.
In the private pathlib ABCs, add a `pathlib._abc.Globber` subclass that works with `PathBase` objects rather than strings, and calls user-defined path methods like `PathBase.stat()` rather than `os.stat()`.
This sets the stage for two more improvements:
- GH-115060: Query non-wildcard segments with `lstat()`
- GH-116380: Unify `pathlib` and `glob` implementations of globbing.
No change to the implementations of `glob.glob()` and `glob.iglob()`.
The `__has_feature(thread_sanitizer)` is a Clang-ism. Although new
versions of GCC implement `__has_feature`, the `defined(__has_feature)`
check still fails on GCC so we don't use that code path.
Moves the validation for invalid years in the C implementation of the `datetime` module into a common location between `fromisoformat` and `fromisocalendar`, which improves the error message and fixes a failed assertion when parsing invalid ISO 8601 years using one of the "ISO weeks" formats.

This prevents external cancellations of a task group's parent task to
be dropped when an internal cancellation happens at the same time.
Also strengthen the semantics of uncancel() to clear self._must_cancel
when the cancellation count reaches zero.

This keeps track of the per-thread total reference count operations in
PyThreadState in the free-threaded builds. The count is merged into the
interpreter's total when the thread exits.
Most mutable data is protected by a striped lock that is keyed on the
referenced object's address. The weakref's hash is protected using the
weakref's per-object lock.
Note that this only affects free-threaded builds. Apart from some minor
refactoring, the added code is all either gated by `ifdef`s or is a no-op
(e.g. `Py_BEGIN_CRITICAL_SECTION`).
The worker thread may still be alive after it enqueues it's last result,
which can lead to a delay of 30 seconds after the test finishes. This
happens much more frequently in the free-threaded build with the GIL
disabled.
This changes run_workers.py to track of live workers by enqueueing a
`WorkerExited()` instance before the worker exits.
The test suite fetches the C recursion limit from the _testcapi
extension module. Test extension modules can be disabled using the
--disable-test-modules configure option.
* remove load extension doctest since we cannot skip it conditionally
* remove sys.unraisablehook example; using unraisable hooks is not "an
improved debug experience"
- re-enable test_fcntl_64_bit on Linux aarch64, but disable it on all
Android ABIs
- use support.setswitchinterval in all relevant tests
- skip test_fma_zero_result on Android x86_64
- accept EACCES when calling os.get_terminal_size on Android
Replace tri-state `follow_symlinks` with boolean `recurse_symlinks` argument. The new argument controls whether symlinks are followed when expanding recursive `**` wildcards. The possible argument values correspond as follows:
follow_symlinks recurse_symlinks
=============== ================
False N/A
None False
True True
We therefore drop support for not following symlinks when expanding non-recursive pattern parts; it wasn't requested in the original issue, and it's a feature not found in any shells.
This makes the API a easier to grok by eliminating `None` as an option.
No news blurb as `follow_symlinks` was new in 3.13.
