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-111178: Fix getsockaddrarg() undefined behavior (GH-131668)
Don't pass direct references to sockaddr members since their type may
not match PyArg_ParseTuple() types. Instead, use temporary 'int' and
'unsigned char' variables, and update sockaddr members afterwards.
On FreeBSD, treat BTPROTO_HCI node name as a bytes string,
not as an integer.

gh-131865: Properly apply exported CFLAGS for dtrace/systemtap builds (GH-131866)
When using --with-dtrace the resulting object file could be missing
specific CFLAGS exported by the build system due to the systemtap
script using specific defaults.
Exporting the CC and CFLAGS variables before the dtrace invocation
allows us to properly apply CFLAGS exported by the build system
even when cross-compiling.
The fix does not affect the dtrace invocation on Solaris/macOS.

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.
(cherry picked from commit c57623c221)
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-131045: [Enum] fix flag containment checks when using values (GH-131053)
Check would fail if value would create a pseudo-member, but that member
had not yet been created. We now attempt to create a pseudo-member for
a passed-in value first.

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`).

gh-130740: Move some `stdbool.h` includes after `Python.h` (#130738)
Move some `#include <stdbool.h>` after `#include "Python.h"` when `pyconfig.h` is not
included first and when we are in a platform-agnostic context. This is to avoid having
features defined by `stdbool.h` before those decided by `Python.h` (this caused some
build failures when compiling CPython with `zig cc`).

The use of PySys_GetObject() and _PySys_GetAttr(), which return a borrowed
reference, has been replaced by using one of the following functions, which
return a strong reference and distinguish a missing attribute from an error:
_PySys_GetOptionalAttr(), _PySys_GetOptionalAttrString(),
_PySys_GetRequiredAttr(), and _PySys_GetRequiredAttrString().
