GH-79033: Fix asyncio.Server.wait_closed() (#98582)
It was a no-op when used as recommended (after close()).

I had to debug one test (test__sock_sendfile_native_failure) --
the cleanup sequence for the test fixture was botched.

Hopefully that's not a portend of problems in user code --
this has never worked so people may well be doing this wrong. :-(

gh-47146: Soft-deprecate structmember.h, expose its contents via Python.h (GH-99014)
The ``structmember.h`` header is deprecated, though it continues to be available
and there are no plans to remove it. There are no deprecation warnings. Old code
can stay unchanged (unless the extra include and non-namespaced macros bother
you greatly). Specifically, no uses in CPython are updated -- that would just be
unnecessary churn.
The ``structmember.h`` header is deprecated, though it continues to be
available and there are no plans to remove it.

Its contents are now available just by including ``Python.h``,
with a ``Py`` prefix added if it was missing:

- `PyMemberDef`, `PyMember_GetOne` and`PyMember_SetOne`
- Type macros like `Py_T_INT`, `Py_T_DOUBLE`, etc.
  (previously ``T_INT``, ``T_DOUBLE``, etc.)
- The flags `Py_READONLY` (previously ``READONLY``) and
  `Py_AUDIT_READ` (previously all uppercase)

Several items are not exposed from ``Python.h``:

- `T_OBJECT` (use `Py_T_OBJECT_EX`)
- `T_NONE` (previously undocumented, and pretty quirky)
- The macro ``WRITE_RESTRICTED`` which does nothing.
- The macros ``RESTRICTED`` and ``READ_RESTRICTED``, equivalents of
  `Py_AUDIT_READ`.
- In some configurations, ``<stddef.h>`` is not included from ``Python.h``.
  It should be included manually when using ``offsetof()``.

The deprecated header continues to provide its original
contents under the original names.
Your old code can stay unchanged, unless the extra include and non-namespaced
macros bother you greatly.

There is discussion on the issue to rename `T_PYSSIZET` to `PY_T_SSIZE` or
similar. I chose not to do that -- users will probably copy/paste that with any
spelling, and not renaming it makes migration docs simpler.

gh-99659: Use correct exceptions in sqlite3 bigmem tests (#99660)
The tests in question were added in 0eec6276fd by Serhiy. Apparently,
sqlite3 changed exceptions raised in those cases in the mean time but
the tests never ran because they require a high `-M` setting in the
test runner.

gh-99370: Calculate zip path from prefix when in a venv (GH-99371)
Before python3.11, when in a venv the zip path is calculated
from prefix on POSIX platforms. In python3.11 the behavior is
accidentally changed to calculating from default prefix. This
change will break venv created from a non-installed python
with a stdlib zip file. This commit restores the behavior back
to before python3.11.

Prevent urllib.parse.urlparse from accepting schemes that don't begin with an alphabetical ASCII character.

RFC 3986 defines a scheme like this: `scheme = ALPHA *( ALPHA / DIGIT / "+" / "-" / "." )`
RFC 2234 defines an ALPHA like this: `ALPHA = %x41-5A / %x61-7A`

The WHATWG URL spec defines a scheme like this:
`"A URL-scheme string must be one ASCII alpha, followed by zero or more of ASCII alphanumeric, U+002B (+), U+002D (-), and U+002E (.)."`

That makes a total of 16 global variables. We are moving all 16 to the _PyRuntimeState struct as part of the work for gh-81057.  (If PEP 684 is accepted then we will follow up by moving them all to PyInterpreterState.)

* fix auto() failure during multiple assignment

i.e. `ONE = auto(), 'text'` will now have `ONE' with the value of `(1,
'text')`.  Before it would have been `(<an auto instance>, 'text')`

gh-92584: Remove the distutils package (#99061)
Remove the distutils package. It was deprecated in Python 3.10 by PEP
632 "Deprecate distutils module". For projects still using distutils
and cannot be updated to something else, the setuptools project can
be installed: it still provides distutils.

* Remove Lib/distutils/ directory
* Remove test_distutils
* Remove references to distutils
* Skip test_check_c_globals and test_peg_generator since they use
  distutils

gh-94172: Remove keyfile, certfile and check_hostname parameters (#94173)
Remove the keyfile, certfile and check_hostname parameters,
deprecated since Python 3.6, in modules: ftplib, http.client,
imaplib, poplib and smtplib. Use the context parameter (ssl_context
in imaplib) instead.

Parameters following the removed parameters become keyword-only
parameters.

ftplib: Remove the FTP_TLS.ssl_version class attribute: use the
context parameter instead.

gh-98401: Invalid escape sequences emits SyntaxWarning (#99011)
A backslash-character pair that is not a valid escape sequence now
generates a SyntaxWarning, instead of DeprecationWarning.  For
example, re.compile("\d+\.\d+") now emits a SyntaxWarning ("\d" is an
invalid escape sequence), use raw strings for regular expression:
re.compile(r"\d+\.\d+"). In a future Python version, SyntaxError will
eventually be raised, instead of SyntaxWarning.

Octal escapes with value larger than 0o377 (ex: "\477"), deprecated
in Python 3.11, now produce a SyntaxWarning, instead of
DeprecationWarning. In a future Python version they will be
eventually a SyntaxError.

codecs.escape_decode() and codecs.unicode_escape_decode() are left
unchanged: they still emit DeprecationWarning.

* The parser only emits SyntaxWarning for Python 3.12 (feature
  version), and still emits DeprecationWarning on older Python
  versions.
* Fix SyntaxWarning by using raw strings in Tools/c-analyzer/ and
  wasm_build.py.

gh-98740: Fix validation of conditional expressions in RE (GH-98764)
In very rare circumstances the JUMP opcode could be confused with the
argument of the opcode in the "then" part which doesn't end with the
JUMP opcode. This led to incorrect detection of the final JUMP opcode
and incorrect calculation of the size of the subexpression.

NOTE: Changed return value of functions _validate_inner() and
_validate_charset() in Modules/_sre/sre.c.  Now they return 0 on success,
-1 on failure, and 1 if the last op is JUMP (which usually is a failure).
Previously they returned 1 on success and 0 on failure.
