According to https://blog.travis-ci.com/2019-04-15-xenial-default-build-environment Ubuntu Xenial is now default, but it lacks python 2.6, 3.2 and 3.3 support needed by tests
Travis now recommends removing `sudo: false` from configuration: https://blog.travis-ci.com/2018-11-19-required-linux-infrastructure-migration.
Let's see how is it verbose now
SOCKS tests never run on Travis CI due to unknown reasons, and downloading them broke some tests (e.g. https://travis-ci.org/rg3/youtube-dl/builds/144306425)
We don't use rtmpdump in tests anyway
travis is much to verbose for that, with random IEs constantly failing
Conflicts: .travis.yml
this was blocking the Vimeo test + some more gentest fixes
