(cherry picked from commit 53a7f76501)

gh-87245: Improve IPv6Address.ipv4_mapped documentation (GH-92572)
Avoid the phrasing ‘starting with ::FFFF/96’, which is confusing since
it seems to mix a prefix and a range. Instead, make it clear what the
actual range is, and refer to the relevant RFC.
Closes GH-87245.

Previously, identical PickleBuffers did not preserve identity.
Also, empty writable PickleBuffer memoized an empty bytearray object
in place of b'' which is a singleton in CPython, so the following
references to b'' were unpickled as an empty bytearray object.

gh-149117: Set `ImportError.name` on errors from `runpy.run_module`/`run_path` (gh-149159)
Set ImportError.name on errors from runpy.run_module/run_path
`runpy.run_module()` and `runpy.run_path()` now set the `name` attribute
of the `ImportError` they raise to the requested module name, matching
the behaviour of a regular import statement (previously `name` was
always `None`, which broke introspection).
The `name=` kwarg is gated on `issubclass(error, ImportError)` because
`_get_module_details()` is also used by `_run_module_as_main()` with
a private `_Error` sentinel class. `_Error` does not subclass
ImportError, and `BaseException.__init__` rejects unknown kwargs at
the C level, so passing `name=` unconditionally would break the
`python -m foo` codepath.

As part of fixing bpo-27931 code was introduced to get_bare_quoted_string
that added an empty Terminal if the quoted string was empty. This isn't
the best answer in terms of the parse tree; we really want the token
list to be empty in that case. But having it be empty resulted in
local_part raising the index error. We find that same problem if we
try to parse an address consisting of a single dquote. By fixing
local_part to not raise on an empty token list, we can have the
bare_quoted_string code correctly return an empty token list for
the empty string cases (two dquotes or a single dquote as the
entire addrespec, at the end of a line).

When an address in an address-list has garbage at the end, the code will
currently:
1. change the mailbox in the last parsed address into invalid-mailbox by
overriding its token_type;
2. wrap the trailing garbage into another invalid-mailbox and append it
to the last parsed address.
However, that does not take into account that an address may
also contain a Group instead of a single mailbox. In that case,
overwriting token_type leads to undesirable results, e.g. parsing an
email with the following 'To' header:
unlisted-recipients:; (no To-header on input)
raises an AttributeError from trying to treat the Group as a Mailbox.
Moreover it is questionable whether the previously parsed mailbox should
be treated as invalid in addition to the trailing garbage.
Address both of the above by wrapping the trailing garbage in a new
Address with a single invalid-mailbox, and append it to the AddressList
directly.
Changes the results of the
test_get_address_list_mailboxes_invalid_addresses test, where the
address list is now parsed into 4 mailboxes instead of 3 (all but the
first one are invalid).

gh-105936: Properly update closure cells for `__setattr__` and `__delattr__` in frozen dataclasses with slots (GH-144021)
(cherry picked from commit 8a398bfbbc)
The cherry-pick required additional changes beyond the original commit
because 3.13 lacks the `__class__` closure cell fixup machinery that
was added in 3.14 by GH-124455 (gh-90562). Specifically:
- Backported `_update_func_cell_for__class__()` helper function and the
closure fixup loop in `_add_slots()` from GH-124455. Without these,
renaming the closure variable from `cls` to `__class__` has no effect
because nothing updates the cell when the class is recreated with slots.
- Changed `_add_slots()` to use `newcls` instead of reusing `cls` for the
recreated class, so both old and new class references are available for
the fixup loop.
- Replaced `assertNotHasAttr` with `assertFalse(hasattr(...))` in tests
(assertNotHasAttr was added in 3.14).
- Dropped `test_original_class_is_gced` additions (that test does not
exist on 3.13; it was added by GH-137047 for gh-135228 which was not
backported to 3.13).
gh-148947: dataclasses: fix error on empty __class__ cell (GH-148948)
Also add a test demonstrating the need for the existing "is oldcls" check.

_PyRawMutex_UnlockSlow CAS-removes the waiter from the list and then
calls _PySemaphore_Wakeup, with no handshake. If _PySemaphore_Wait
returns Py_PARK_INTR, the waiter can destroy its stack-allocated
semaphore before the unlocker's Wakeup runs, causing a fatal error from
ReleaseSemaphore / sem_post.
Loop in _PyRawMutex_LockSlow until _PySemaphore_Wait returns Py_PARK_OK,
which is only signalled when a matching Wakeup has been observed.
Also include GetLastError() and the handle in the Windows fatal messages
in _PySemaphore_Init, _PySemaphore_Wait, and _PySemaphore_Wakeup to make
similar races easier to diagnose in the future.
