Ubuntu Linux 20.04 LTS Focal Fossa is now open for development

Focal Fossa is now open for development, with the syncs from unstable
done and built, and autopkg testers trying to catch up. The development version
starts with only a few changes:

- Python 3.8 is now added as a supported Python3 version, with the
goal to ship Python 3.8 as the only Python3 version in focal.
Details will follow on the ubuntu-devel ML.

- Perl was updated to version 5.30.

- s390x is now built targeting z13 (GCC only for now).

- While the Python2 removals imported from Debian are just
syncs like any others, it's worth pointing out that
some uncoordinated removals are causing some churn [3],
and on top of that there is a Ubuntu dept/delta which needs to
see fixing as well [4].

Please check your uploads in a focal chroot, don't just test in a eoan or bionic
environment. See [1] or [2] how to setup such a development chroot.
