[Buildroot] [PATCH 0/7] Switch to Python 3.x flake8

[Thomas Petazzoni]

Hello,

Now that we are using the "async" keyword and related Python 3.x
functionality in support/scripts/pkg-stats, our check-flake8 Gitlab CI
job no longer passes:

  https://gitlab.com/buildroot.org/buildroot/-/jobs/681711009

It borks on the "async" keyword. The purpose of this series is to
switch to using the Python 3.x flake8.

Patches 1 to 5 fix existing issues in our Python codebase which were
accepted by the Python 2.x flake8, but not the Python 3.x flake8.

Patch 6 changes our Dockerfile to install python3-flake8 instead of
python-flake8, and patch 7 changes our Gitlab CI job to use the
Python3 flake8 checker.

Once patch 6 is applied, someone will have to rebuild and upload the
Docker image that Buildroot's Gitlab CI is using, and re-adjust patch
7 before applying it to use the new Docker image.

Thanks,

Thomas
