This adds two new methods to `multiprocessing`'s `ProcessPoolExecutor`:
- **`terminate_workers()`**: forcefully terminates worker processes using `Process.terminate()`
- **`kill_workers()`**: forcefully kills worker processes using `Process.kill()`
These methods provide users with a direct way to stop worker processes without `shutdown()` or relying on implementation details, addressing situations where immediate termination is needed.

Commit-message-mostly-authored-by: Claude Sonnet 3.7 (because why not -greg)
The value taken by `FrameSummary.end_lineno` when passing `end_lineno=None` changed in gh-112097.
Previously, a `end_lineno` could be specified to be `None` directly but since 939fc6d, passing None makes
the constructor use the value of `lineno` instead.
Add support for generating UUIDv6 objects according to RFC 9562, §5.6 [1].
The functionality is provided by the `uuid.uuid6()` function which takes as inputs an optional 48-bit
hardware address and an optional 14-bit clock sequence. The UUIDv6 temporal fields are ordered
differently than those of UUIDv1, thereby providing improved database locality.

This broke tests on the 'aarch64 Fedora Stable Clang Installed 3.x' and
'AMD64 Fedora Stable Clang Installed 3.x' build bots.
This reverts commit da4899b94a.
## Filtered recursive walk
Expanding a recursive `**` segment entails walking the entire directory
tree, and so any subsequent pattern segments (except special segments) can
be evaluated by filtering the expanded paths through a regex. For example,
`glob.glob("foo/**/*.py", recursive=True)` recursively walks `foo/` with
`os.scandir()`, and then filters paths through a regex based on "`**/*.py`,
with no further filesystem access needed.
This fixes an issue where `glob()` could return duplicate results.
## Tracking path existence
We store a flag alongside each path indicating whether the path is
guaranteed to exist. As we process the pattern:
- Certain special pattern segments (`""`, `"."` and `".."`) leave the flag
unchanged
- Literal pattern segments (e.g. `foo/bar`) set the flag to false
- Wildcard pattern segments (e.g. `*/*.py`) set the flag to true (because
children are found via `os.scandir()`)
- Recursive pattern segments (e.g. `**`) leave the flag unchanged for the
root path, and set it to true for descendants discovered via
`os.scandir()`.
If the flag is false at the end, we call `lstat()` on each path to filter
out missing paths.
## Minor speed-ups
- Exclude paths that don't match a non-terminal non-recursive wildcard
pattern _prior_ to calling `is_dir()`.
- Use a stack rather than recursion to implement recursive wildcards.
- This fixes a recursion error when globbing deep trees.
- Pre-compile regular expressions and pre-join literal pattern segments.
- Convert to/from `bytes` (a minor use-case) in `iglob()` rather than
supporting `bytes` throughout. This particularly simplifies the code
needed to handle relative bytes paths with `dir_fd`.
- Avoid calling `os.path.join()`; instead we keep paths in a normalized
form and append trailing slashes when needed.
- Avoid calling `os.path.normcase()`; instead we use case-insensitive regex
matching.
## Implementation notes
Much of this functionality is already present in pathlib's implementation
of globbing. The specific additions we make are:
1. Support for `dir_fd`
2. Support for `include_hidden`
3. Support for generating paths relative to `root_dir`
This unifies the implementations of globbing in the `glob` and `pathlib`
modules.

Add two optional, traling elements in the AF_BLUETOOTH socket address tuple:
- l2_cid, to allow e.g raw LE ATT connections
- l2_bdaddr_type. To be able to connect L2CAP sockets to Bluetooth LE devices,
the l2_bdaddr_type must be set to BDADDR_LE_PUBLIC or BDADDR_LE_RANDOM.
* Implement C recursion protection with limit pointers for Linux, MacOS and Windows
* Remove calls to PyOS_CheckStack
* Add stack protection to parser
* Make tests more robust to low stacks
* Improve error messages for stack overflow
* Clarify sys.getdefaultencoding() documentation
* Add missing documentation for PyUnicode_GetDefaultEncoding,
the C equivalent of sys.getdefaultencoding
Revert "GH-91079: Implement C stack limits using addresses, not counters. (GH-130007)" for now
Unfortunatlely, the change broke some buildbots.
This reverts commit 2498c22fa0.

The SyncManager provided support for various data structures such as dict, list, and queue, but oddly, not set.
This introduces support for set by defining SetProxy and registering it with SyncManager.

Deprecate private C API functions:
* _PyUnicodeWriter_Init()
* _PyUnicodeWriter_Finish()
* _PyUnicodeWriter_Dealloc()
* _PyUnicodeWriter_WriteChar()
* _PyUnicodeWriter_WriteStr()
* _PyUnicodeWriter_WriteSubstring()
* _PyUnicodeWriter_WriteASCIIString()
* _PyUnicodeWriter_WriteLatin1String()
These functions are not deprecated in the internal C API (if the
Py_BUILD_CORE macro is defined).
