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.

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.

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

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.

Rather than directly download distro images from the test scripts, handle
all the downloads during the test asset build, then just clone them for
the tests themselves. This avoids repeated downloads which can be very
slow when debugging failing tests.

Apparently qemu's ARM virt machine needs to be explicitly given a firmware
image, rather than just supplying a sane default. Unfortunately the EDK2
firmware image we need isn't in the same place on all host distros.
Currently the test scripts hardcode the Debian location, meaning it will
break on hosts that have it somewhere else. This patch searches multiple
locations for the firmware, and creates a local link during the asset build
phase, which the tests can then use.
For now it only searches the locations used by Debian and Fedora, but
that's a small improvement in robustness already, and can be later improved
further if we need to.

A lot of tests and examples invoke qemu with the command "kvm". However,
as far as I can tell, "kvm" being aliased to the appropriate qemu system
binary is Debian specific. The binary names from qemu upstream -
qemu-system-$ARCH - also aren't universal, but they are more common (they
should be good for both Debian and Fedora at least).
In order to still get KVM acceleration when available, we use the option
"-M accel=kvm:tcg" to tell qemu to try using either KVM or TCG in that
order
A number of the places we invoked "kvm" are expecting specifically an x86
guest, and so it's also safer to explicitly invoke qemu-system-x86_64.
Some others appear to be independent of the target arch (just wanting the
same arch as the host to allow KVM acceleration). Although I suspect there
may be more subtle x86 specific options in the qemu command lines, attempt
to preserve arch independence by using $(uname -m).

There are several places which explicitly list the various generated
binaries, even though a $(BIN) variable already lists them. There are
several more places that list all the manpage files, introduce a
$(MANPAGES) variable to remove that repetition as well.
Tweak the generation of pasta.1 as a link to passt.1 so it's not just made
as a side effect of the pasta target.

for success of all issued commands as a matter of course, we no longer need

The shell might report 'nc -6 -l -p 9999 > /tmp/ns_msg' as done
even after the subsequent 'echo' is done: wait one second before
reading out /tmp/ns_msg, to ensure we read that instead of the
"Done" message.

The new tests check build and a simple case with pasta sending a
short message in both directions (namespace to init, init to
namespace).
Tests cover a mix of Debian, Fedora, OpenSUSE and Ubuntu combinations
on aarch64, i386, ppc64, ppc64le, s390x, x86_64.
Builds tested starting from approximately glibc 2.19, gcc 4.7, and
actual functionality approximately from 4.4 kernels, glibc 2.25,
gcc 4.8, all the way up to current glibc/gcc/kernel versions.
