Represent IPv4-mapped IPv6 address as x❌x❌x❌d.d.d.d,
where the 'x's are the hexadecimal values
of the six high-order 16-bit pieces of the address,
and the 'd's are the decimal values
of the four low-order 8-bit pieces of the address
(standard IPv4 representation).

If the error handler is used, a new bytes object is created to set as
the object attribute of UnicodeDecodeError, and that bytes object then
replaces the original data. A pointer to the decoded data will became invalid
after destroying that temporary bytes object. So we need other way to return
the first invalid escape from _PyUnicode_DecodeUnicodeEscapeInternal().
_PyBytes_DecodeEscape() does not have such issue, because it does not
use the error handlers registry, but it should be changed for compatibility
with _PyUnicode_DecodeUnicodeEscapeInternal().

When replace() method is called on a subclass of datetime, date or time,
properly call derived constructor. Previously, only the base class's
constructor was called.
Also, make sure to pass non-zero fold values when creating subclasses in
various methods. Previously, fold was silently ignored.

gh-126037: fix UAF in `xml.etree.ElementTree.Element.find*` when concurrent mutations happen (#127964)
We fix a use-after-free in the `find`, `findtext` and `findall` methods of `xml.etree.ElementTree.Element`
objects that can be triggered when the tag to find implements an `__eq__` method that mutates the
element being queried.

The bin tag is 3.0.16.1 because we rebuilt without uplink support to fix gh-131804.
This PR also prevents making calls that are now unsafe without uplink, and updates
the tests to property interpret these failures as unsupported.

gh-121284: Fix email address header folding with parsed encoded-word (GH-122754)
Email generators using email.policy.default may convert an RFC 2047
encoded-word to unencoded form during header refolding. In a structured
header, this could allow 'specials' chars outside a quoted-string,
leading to invalid address headers and enabling spoofing. This change
ensures a parsed encoded-word that contains specials is kept as an
encoded-word while the header is refolded.
[Better fix from @bitdancer.]

Fix the pure Python implementation of `fromisoformat()` to reject any
non-digit characters, including whitespace, in the fractional part
of time specification. This makes the behavior consistent with the C
implementation, and prevents incorrect parsing of these fractions
(e.g. `.400 ` would be misinterpreted as `.04`).
