This does not remove any prior versions: LibreSSL versions are
maintained for a year after their corresponding OpenBSD branch is tagged
for release:
- v2.6.x, part of OpenBSD 6.2-release, Nov 2017 (EOL: Nov 2018)
- v2.7.x, part of OpenBSD 6.3-release, Apr 2018 (EOL: Apr 2019)
- v2.8.x, expected OpenBSD 6.4-release, ETA Sep 2018 (EOL: Sep 2019)
This also does not change the default version: the stable branch remains
2.7.x, and 2.8.0 is the newest released development version. 2.8 can
become the default after OpenBSD-6.4
Closes#44760 (as it's redundant).
