bpo-46811: Make test suite support Expat >=2.4.5 (GH-31453)
Curly brackets were never allowed in namespace URIs
according to RFC 3986, and so-called namespace-validating
XML parsers have the right to reject them a invalid URIs.
libexpat >=2.4.5 has become strcter in that regard due to
related security issues; with ET.XML instantiating a
namespace-aware parser under the hood, this test has no
future in CPython.
Since `.. module:: contextvars` sets the module using `.. class:: contextvars.Token`, intersphinx records it as `contextvars.contextvars.Token`.

bpo-45436: Fix tkinter tests with Tcl/Tk 8.6.11+ (GH-29077) (GH-29093)
Since v8.6.11, a few configuration options seem to accept an empty value
where they did not previously; particularly the `type` of a `Menu`
widget, and the `compound` of any ttk widget with a label. Providing an
explicit expected error message to `checkEnumParam` bypasses the check
of an empty value, which no longer raises `TclError`.

bpo-45001: Make email date parsing more robust against malformed input (GH-27946) (GH-27974)
Various date parsing utilities in the email module, such as
email.utils.parsedate(), are supposed to gracefully handle invalid
input, typically by raising an appropriate exception or by returning
None.
The internal email._parseaddr._parsedate_tz() helper used by some of
these date parsing routines tries to be robust against malformed input,
but unfortunately it can still crash ungracefully when a non-empty but
whitespace-only input is passed. This manifests as an unexpected
IndexError.
In practice, this can happen when parsing an email with only a newline
inside a ‘Date:’ header, which unfortunately happens occasionally in the
real world.
Here's a minimal example:
$ python
Python 3.9.6 (default, Jun 30 2021, 10:22:16)
[GCC 11.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import email.utils
>>> email.utils.parsedate('foo')
>>> email.utils.parsedate(' ')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.9/email/_parseaddr.py", line 176, in parsedate
t = parsedate_tz(data)
File "/usr/lib/python3.9/email/_parseaddr.py", line 50, in parsedate_tz
res = _parsedate_tz(data)
File "/usr/lib/python3.9/email/_parseaddr.py", line 72, in _parsedate_tz
if data[0].endswith(',') or data[0].lower() in _daynames:
IndexError: list index out of range
The fix is rather straight-forward: guard against empty lists, after
splitting on whitespace, but before accessing the first element.

[3.8] bpo-36384: Leading zeros in IPv4 addresses are no longer tolerated (GH-25099) (GH-27801)
Reverts commit e653d4d8e820a7a004ad399530af0135b45db27a and makes
parsing even more strict. Like socket.inet_pton() any leading zero
is now treated as invalid input.

The address tuple for CAN_RAW no longer returns the address family
after the introduction of CAN ISO-TP support in a30f6d45ac3. However,
updating test_socket.CANTest.testSendFrame was missed as part of the
change, so the test incorrectly attempts to index past the last tuple
item to retrieve the address family.
This removes the now-redundant check for equality against socket.AF_CAN,
as the tuple will not contain the address family.

* bpo-41100: Support macOS 11 and Apple Silicon on Python 3.8
This is a partial backport of bpo-41100 changes `e8b1c038b14b5fc8120aab62c9bf5fb840274cb6` and `96d906b144e6e6aa96c5ffebecbcc5d38034bbda` for Python 3.8. We introduce the ability to build Python from source for `arm64` on macOS, but we do not make a promise of support. This allows us to omit support for Universal2 binaries as well as weak-linking of symbols from the macOS SDK based on the deployment target, which are larger changes much more difficult to merge.
