[PATCH 0/7] Do not support Debian 9 and Python 3.5 anymore

[Thomas Huth]

Debian 9 is EOL now, and according to our support policy, we do not
support it anymore. Let's switch the corresponding CI builds to
either Fedora (for a more recent version of the MinGW compilers) or
Debian 10 instead.

Together with the Travis patch series that I recently posted ("Update
Travis from Xenial to Bionic and Focal"), our CI should now be free of
distros that we do not support anymore. And all supported build systems
now use at least Python 3.6, so we can drop the support for Python 3.5.

Based-on: <20200918103430.297167-1-thuth@redhat.com>
