Description

We should update the bundled libevent to 2.1.8-stable. Alternatively, we might even consider unbundling given that we have no strict version or patch constraints on that dependency. Anything installed by an up-to-date package manager should be fine.

Changes since from 2.0.22 to 2.1.8: https://github.com/libevent/libevent/compare/c51b159cff9f5e86696f5b9a4c6f517276056258...e7ff4ef2b4fc950a765008c18e74281cdb5e7668
