Fixes the following security issues:
- bpo-40121: Fixes audit events raised on creating a new socket
- bpo-38576: Disallow control characters in hostnames in http.client,
addressing CVE-2019-18348. Such potentially malicious header injection
URLs now cause a InvalidURL to be raised.
- bpo-39503: CVE-2020-8492: The AbstractBasicAuthHandler class of the
urllib.request module uses an inefficient regular expression which can be
exploited by an attacker to cause a denial of service. Fix the regex to
prevent the catastrophic backtracking. Vulnerability reported by Ben
Caller and Matt Schwager.
