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.

The current debian cloud images no longer include ppc64.  Change to using
the latest snapshot which does include ppc64.

qemu commit 13c6be96618c ("net: stream: add unix socket") introduces
support for native AF_UNIX support, finally making qrap useless.

We can't quite drop that yet until a qemu release includes it, and
then we'll need to wait a while for users to switch anyway, but at
least for tests, we can use that support.

If we use dhclient without creating a complete network configuration,
systemd-resolved will stop working after a while, and this sometimes
happens while we're still installing packages.

Disable it, together with systemd-networkd, while taking care of
removing the dhclient hook that prevents overriding /etc/resolv.conf.

While at it, it looks like removing snapd and needrestart actually
takes more time than keeping them: drop that line.

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

On new Ubuntu 22.04 images, stopping systemd-resolved to get the
dhclient script override resolv.conf doesn't work anymore. I
originally used that hack to avoid introducing a delay which is
needed when running it on TCG.

Keep systemd-resolved running instead, and wait for it to be ready
by retrying to resolve a domain a few times before installing
packages, so that we don't add another ugly delay that might
unnecessarily slow down things even further.

We start getting prompts about restarting outdated services: we're
using daily images but they might have been cached for a while now.

We've recently converted most of our tests to use socat instead of
nc/netcat/ncat, because socat is more powerful and we don't need to deal
with the several possible variants of netcat.

We still use nc or ncat for the distro tests.  Because there we control
the guest environment and can pick our tools, there isn't the same reason
to switch to socat.  However, using socat here as well makes the tests
a bit easier to read, and doesn't require people reading or modifying them
to become familiar with an additional tool.

Distribution packages reasonably expect to have a human-readable
Markdown version of the README under /usr/share/doc/, but all we have
right now is a heavily web-oriented version.

Introduce a ugly hack to strip web-oriented parts from the current
README and install it.

It should probably work the other way around: a human-readable README
could be used as a source for the web page. But cgit needs a file
that's in the tree, not something that can be built, and
https://passt.top/ is based on cgit. It should eventually be doable
to work around this in cgit, instead.

A couple of days ago, we started running out of space there as we're
about to install gcc -- about 50 MiB are missing.

Given that virt-resize (which could be conveniently invoked by the
Makefile for tests) reorders partitions if we expand the first one,
resize the image using qemu-img from the test script itself, and then
take care of expanding root partition and filesystem online later.

This is probably a temporary hack, so I'm not looking for a more
generic or elegant solution at the moment.
