• The output currently contains a large number of false-positives and — AFAICT —
no actual issues.
• Upstream shows little interest in addressing the long-standing issues with the
TAILQ macros, so the false-positive situation probably won’t change soon:

Currently, we largely spend travis CPU cycles on this, for no additional value.
The resulting packages are pushed to Debian repositories hosted on
bintray.com.
This is the first step to move away from our custom buildbot setup (see
https://i3wm.org/docs/buildbot.html for details on that) towards
infrastructure which is more standard (travis) and in the open.
We now build a docker base container based on debian sid (where the very
latest packages are available). That base container is updated once a
month, or whenever travis-build.Dockerfile or debian/control change, but
re-used for subsequent travis runs. While the initial build might take
up to 15 minutes, subsequent builds typically run in a minute or two.
All the different steps that we run on travis are now factored into
separate scripts in the travis/ directory.
Switching to docker should also help with issue #2174.
This will ensure that our code stays free of warnings, at least for the
warnings that we have enabled. (Using _FORTIFY_SOURCE > 0 leads to more
warnings, some of them are harder to address.)
