rework result printing

See merge request !8

new script printresults.py replaces old nsprint.py and diffresults.py

Bugfixes

See merge request !7

The multiprocessing module by default uses fork() on Linux
and this effectively doubles amount of memory required for processing
big zones.

We are targeting Linux platform anyway so using forkserver should not
have any adverse effect.

This algorithm works better on large zones and produces the same result.

All-in-one script

See merge request !6

It now produces the same result as each individual script, including
pickled intermediate results.

It seems to work but the script does not save its results yet.

Python version will be handy for all-in-one script.

ci: fix prod image build

See merge request !5

ci: fix lint + test phase by actually adding CI docker image

See merge request !4

It is not necessary to repeat test 10 times in CI, 2 rounds will
suffice.

ci: add lint + test steps

See merge request !3

prepare CI image

See merge request !2

10 times should be enough to eliminate random network failures.

Supporting Python < 3.6.1 required an ugly hack which was breaking mypy
so I've decided to get rid of it. After all it is always possible to use
Docker container to get a new Python runtime without system
modification.

Right now it does zone2pickle + nsname2ipset steps but does not
persist results.

methodology: ignore EDNS 1 timeouts as irrelevent to 2019 DNS Flag Day

See merge request !1

EDNS 1 problems will "downgrade" results to "compatible" level but will
not cause domain to drop into "high_latency" or "dead" levels

Intent is to run domain2ipset and nsname2ipset in loop until they do not
run out of input or further progress is impossible/very slow.
