bpo-44394: 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.

bpo-43124: Made the internal putcmd function in smtplib sanitize input for
presence of \r and \n characters to avoid (unlikely) command injection.

bpo-36384: ipaddress module no longer accepts any leading zeros in IPv4
address strings. Leading zeros are ambiguous and interpreted as octal
notation by some libraries. For example the legacy function
socket.inet_aton() treats leading zeros as octal notation. glibc
implementation of modern inet_pton() does not accept any leading zeros.
For a while the ipaddress module used to accept ambiguous leading zeros.

It was discovered that Python incorrectly handled certain RFCs.

This issue only affected Ubuntu 16.04 ESM. (CVE-2021-3733)
