It took some time until Cirrus CI allowed me to run tests against my new
GitHub account (there's a 3 days freeze to avoid people from getting
Cirrus CI nodes to mine bitcoins :-D). Attached now the latest patch
which passes builds, rebased on latest master.
I also reviewed the first two patches a while ago in [1]. I hope we can
progress with them to further reduce the size of this patch set.
Beyond that: I could work on support for more OSs (e.g. starting with
Windows). Is there appetite for that or do we rather want to instead
start with a smaller patch?
