New branch considers all files changed. We don't want to rebuild all
docker images for new branches; that's just a waste of time and energy.

There is a better way for future -- a much better fine-grained control
may be obtained by running secondary pipelines.

fixes #212

Possible commands are stored as keywords, each keyword has its own structure.
The last acceptable keyword structure contains string with hint. But when the hint was printed only direct child
of the base keyword was considered. If it was multi keyword command, the first child did not carry any hint to print,
so it was ignored.

Now, if we don't find a hint in a child, we recursively search in grandchildren.

The build-netlab job was side-effecting the test-* jobs,
and if for some reason Gitlab scheduled build-netlab before
other pipeline's test-* jobs finished, these jobs got a wrong
binary, possibly failing. Solved by using explicit artifacts, which is
not the fastest way to do this (we could keep the binaries named there)
but it's the gitlab-right way to do this.

(Re-committed, was accidentally removed by one of previous commits)

Forgetting to do proper checks, I merged a buggy release tools update
not detecting the right version (mostly if tagged).

Fixed and added current distros, deleted certain EOL distros,
sorted things in the CI file.

With some heavy lifting and comments by Maria.

The AO socket dumping is bonkers but we'll fix it later.

Fedora builds for 32-41, Debian up to 12, Ubuntu up to 24.10.

Includes autorebuilder if a Dockerfile changes.

The CI file is obnoxiously boilerplaty. TODO: generate it from a list?

Also version detection is done by a separate script, not a magic line in
the Makefile.

Some minor changes were done in the original documentation to allow for
easier conversion, and also to make the documentation a little bit more
strictly valid.
