gh-102304: doc: Add links to Stable ABI and Limited C API (#105345)
* Add "limited-c-api" and "stable-api" references.
* Rename "stable-abi-list" reference to "limited-api-list".
* Makefile: Document files regenerated by "make regen-limited-abi"
* Remove first empty line in generated files:
Display the sanitizer config in the regrtest header. (#105301)
Display the sanitizers present in libregrtest.
Having this in the CI output for tests with the relevant environment
variable displayed will help make it easier to do what we need to
create an equivalent local test run.

gh-104690 Disallow thread creation and fork at interpreter finalization (#104826)
Disallow thread creation and fork at interpreter finalization.
in the following functions, check if interpreter is finalizing and raise `RuntimeError` with appropriate message:
* `_thread.start_new_thread` and thus `threading`
* `posix.fork`
* `posix.fork1`
* `posix.forkpty`
* `_posixsubprocess.fork_exec` when a `preexec_fn=` is supplied.

gh-101524: Only Use Public C-API in the _xxsubinterpreters Module (gh-105258)
The _xxsubinterpreters module was meant to only use public API. Some internal C-API usage snuck in over the last few years (e.g. gh-28969). This fixes that.

gh-104614: Make Sure ob_type is Always Set Correctly by PyType_Ready() (gh-105122)
When I added the relevant condition to type_ready_set_bases() in gh-103912, I had missed that the function also sets tp_base and ob_type (if necessary). That led to problems for third-party static types.
We fix that here, by making those extra operations distinct and by adjusting the condition to be more specific.
gh-103142: Upgrade binary builds and CI to OpenSSL 1.1.1u (#105174)
Upgrade builds to OpenSSL 1.1.1u.
This OpenSSL version addresses a pile if less-urgent CVEs since 1.1.1t.
The Mac/BuildScript/build-installer.py was already updated.
Also updates _ssl_data_111.h from OpenSSL 1.1.1u, _ssl_data_300.h from 3.0.9, and adds a new _ssl_data_31.h file from 3.1.1 along with the ssl.c code to use it.
Manual edits to the _ssl_data_300.h file prevent it from removing any existing definitions in case those exist in some peoples builds and were important (avoiding regressions during backporting).
backports of this prior to 3.12 will not include the openssl 3.1 header.
All current systems provide time.h; it need not be checked for.
Not all systems provide sys/time.h, but those that do, all allow
you to include it and time.h simultaneously.

gh-105156: Cleanup usage of old Py_UNICODE type (#105158)
* refcounts.dat:
* Remove Py_UNICODE functions.
* Replace Py_UNICODE argument type with wchar_t.
* _PyUnicode_ToLowercase(), _PyUnicode_ToUppercase(),
_PyUnicode_ToTitlecase() are no longer deprecated in comments.
It's no longer needed since they now use Py_UCS4 type, rather than
the deprecated Py_UNICODE type.
* gdb: Remove unused char_width() method.
Update Doc/extending/embedding.rst and Doc/extending/extending.rst to
use the new PyConfig API.
_testembed.c:
* check_stdio_details() now sets stdio_encoding and stdio_errors
of PyConfig.
* Add definitions of functions removed from the API but kept in the
stable ABI.
* test_init_from_config() and test_init_read_set() now use
PyConfig_SetString() instead of PyConfig_SetBytesString().

gh-105020: Share tp_bases and tp_mro Between Interpreters For All Static Builtin Types (gh-105115)
In gh-103912 we added tp_bases and tp_mro to each PyInterpreterState.types.builtins entry. However, doing so ignored the fact that both PyTypeObject fields are public API, and not documented as internal (as opposed to tp_subclasses). We address that here by reverting back to shared objects, making them immortal in the process.

GH-73435: Implement recursive wildcards in `pathlib.PurePath.match()` (#101398)
`PurePath.match()` now handles the `**` wildcard as in `Path.glob()`, i.e. it matches any number of path segments.
We now compile a `re.Pattern` object for the entire pattern. This is made more difficult by `fnmatch` not treating directory separators as special when evaluating wildcards (`*`, `?`, etc), and so we arrange the path parts onto separate *lines* in a string, and ensure we don't set `re.DOTALL`.
