- [Security] bpo-30585: Fix TLS stripping vulnerability in smptlib,
CVE-2016-0772. Reported by Team Oststrom

- [Security] bpo-30694: Upgrade expat copy from 2.2.0 to 2.2.1 to get fixes
of multiple security vulnerabilities including: CVE-2017-9233 (External
entity infinite loop DoS), CVE-2016-9063 (Integer overflow, re-fix),
CVE-2016-0718 (Fix regression bugs from 2.2.0's fix to CVE-2016-0718)
and CVE-2012-0876 (Counter hash flooding with SipHash).
Note: the CVE-2016-5300 (Use os-specific entropy sources like getrandom)
doesn't impact Python, since Python already gets entropy from the OS to set
the expat secret using ``XML_SetHashSalt()``.
