Add `@needs_symlinks` decorator for tests that require symlink support in
the path class.
Also add `@needs_windows` and `@needs_posix` decorators for tests that
require a specific a specific path flavour. These aren't much used yet, but
will be later.
``platform.architecture()`` now returns the format of binaries (e.g. Mach-O) instead of the default empty string.

Add `ntpath.isreserved()`, which identifies reserved pathnames such as "NUL", "AUX" and "CON".
Deprecate `pathlib.PurePath.is_reserved()`.

- consistently use correct parameter markup
- consistently use submodule name as database name
- improve accuracy of the dbm.dumb.open() spec
- remove dumbdbm class refs and replace them with generic "database object"
- use parameter list for dbm.dumb.open()
- add abbreviation directives for NDBM and GDBM
- consistently spell NDBM as NDBM
- silence broken ndbm class refs
- improve accuracy of dbm.ndbm.open() spec
- use replacement text for NDBM/GDBM file format incompatibility note
- add refs to other parts of the docs (dict, bytes, etc.)
- clarify whichdb() return value by using list markup
- silence refs to example or generic submodule methods (keys, get, etc.)
In 49f90ba we added support for the recursive wildcard `**` in
`pathlib.PurePath.match()`. This should allow arbitrary prefix and suffix
matching, like `p.match('foo/**')` or `p.match('**/foo')`, but there's a
problem: for relative patterns only, `match()` implicitly inserts a `**`
token on the left hand side, causing all patterns to match from the right.
As a result, it's impossible to match relative patterns from the left:
`PurePath('foo/bar').match('bar/**')` is true!
This commit reverts the changes to `match()`, and instead adds a new
`full_match()` method that:
- Allows empty patterns
- Supports the recursive wildcard `**`
- Matches the *entire* path when given a relative pattern
`threading.Lock` is now the underlying class and is constructable rather than the old
factory function. This allows for type annotations to refer to it which had no non-ugly
way to be expressed prior to this.

* gh-112529: Implement GC for free-threaded builds
This implements a mark and sweep GC for the free-threaded builds of
CPython. The implementation relies on mimalloc to find GC tracked
objects (i.e., "containers").
* Bring in a subset of biased reference counting:
https://github.com/colesbury/nogil/commit/b6b12a9a94e
The NoGIL branch has functions for attempting to do an incref on an object which may or may not be in flight. This just brings those functions over so that they will be usable from in the dict implementation to get items w/o holding a lock.
There's a handful of small simple modifications:
Adding inline to the force inline functions to avoid a warning, and switching from _Py_ALWAYS_INLINE to Py_ALWAYS_INLINE as that's available
Remove _Py_REF_LOCAL_SHIFT as it doesn't exist yet (and is currently 0 in the 3.12 nogil branch anyway)
ob_ref_shared is currently Py_ssize_t and not uint32_t, so use that
_PY_LIKELY doesn't exist, so drop it
_Py_ThreadLocal becomes _Py_IsOwnedByCurrentThread
Add '_PyInterpreterState_GET()' to _Py_IncRefTotal calls.
