Update the vendored copy of libexpat to 2.4.1 (from 2.2.8) to get the fix

for the CVE-2013-0340 "Billion Laughs" vulnerability. This copy is most used

on Windows and macOS.

Made the internal ``putcmd`` function in :mod:`smtplib` sanitize input for

presence of ``\r`` and ``\n`` characters to avoid (unlikely) command

injection.

Made email date parsing more robust against malformed input, namely a

whitespace-only ``Date:`` header. Patch by Wouter Bolsterlee.

Fix test_faulthandler on GCC 10. Use the "volatile" keyword in

``faulthandler._stack_overflow()`` to prevent tail call optimization on any

compiler, rather than relying on compiler specific pragma.

This is Python version 3.6.15
