In practical terms, passt doesn't benefit from the additional
protection offered by the AGPL over the GPL, because it's not
suitable to be executed over a computer network.
Further, restricting the distribution under the version 3 of the GPL
wouldn't provide any practical advantage either, as long as the passt
codebase is concerned, and might cause unnecessary compatibility
dilemmas.

That's the default port for iperf3, which also means that it's quite
likely in use on my test machine. Use different port numbers: recycle
the scheme we use in tests for passt and pasta's demo, use 5221-5224
(a bit shorter) for the slirp4netns container in Podman's demo.

Instead of using the 'temp' and 'tempdir' DSL directives to create
temporary files, use fixed paths relative to __STATEDIR__. This has two
advantages:
1) The files are automatically cleaned up if the tests fail (and even if
that doesn't work they're easier to clean up manuall)
2) When debugging tests it's easier to figure out which of the temporary
files are relevant to whatever's going wrong

Given that a three-way git merge was enough to cope with context
changes in man pages, it's probably a good idea to enable that for
'git am' in the demo too.

For some reason, I now have to update some "vendored" dependencies
on a fresh git clone, at least in my environment, before building.

Currently test/run uses wildcards to run all of the tests in a directory.
However, that wildcard list is filtered down by the "onlyfor" directives
in the test files... usually to a single file.
Therefore, just explicitly list the files we *really* want to run for this
test mode. This makes it easier to see at the top level what tests will
be executed, and to change that list temporarily while debugging specific
failures.
This means the "onlyfor" directive no longer has any purpose, and we can
remove it. "onlyfor" was also the only used of the $MODE variable, so we
can remove that too.

ip(8)'s ability to take abbreviated arguments (e.g. "li sh" instead of
"link show") is very handy when using it interactively, but it doesn't make
for very readable scripts and examples when shown that way.

Reflect the recent changes in the Podman adaptation (no port
forwarding by default).
It turns out that by running two iperf3 processes, sometimes
slirp4netns blocks the second connection until the first test is
done, thus doubling the throughput. Use a single process for
slirp4netns with slirp4netns port handling.
