[PATCH v2 0/5] make htmldocs in CI

[Heinrich Schuchardt]

This patch series provides a htmldocs target for Travis, Gitlab and Azure
CI.

doc/sphinx/kerneldoc.py is updated to avoid a build warning with current
Sphinx.

The last patch turns build warnings of 'make htmldocs' into errors.

While first four patches can be immediately merged the last patch requires
an updated Docker image, cf.
