667397db11 test: Switch to qemu -netdev stream option instead of using qrap
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.

d6f865a40a test/distro: Update workarounds for Ubuntu 22.04 on s390x
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.

1c36c8d3f8 test: Use paths in __STATEDIR__ instead of 'temp' and 'tempdir' directives
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

c880747883 test: Wait for systemd-resolved to be ready on Ubuntu 22.04 for s390x
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.

a8598c7e70 test: Convert distro tests to use socat instead of nc/ncat
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.

c5f4ba1b1b Makefile: Ugly hack to get a "plain" Markdown version of README
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.

30ac86823b tests: Remove unused DNS6 calculation from fedora tests
The Fedora test file extracts some information from the host resolv.conf
into a DNS6 variable which is then never used.  Remove this unnecessary
step, which is presumably a leftover from an earlier iteration.

This was the only user of 'head' and 'sed' in the test file, so those can
also be removed from the required tools.  The debian and ubuntu test files
also listed 'head' and 'sed' as tools, although they don't use them,
I'm guessing because of an earlier version which had the same DNS6 code.
Remove those as well.

The opensuse test file still actually uses DNS6, so leave it there for now.
The DNS handling and network config handling for SuSE looks to be kind of
broken, but fixing that is a job for another day.

d2802ec874 tests: Prepare distro images during asset build phase
Before booting the guest images, the distro test cases need to modify the
guest images, using virt-edit and guestfish, to boot in the way we need.
At present this gets repeated on every test run, even though it's not
really doing anything we want to test for.

In addition many of the images have the same preparation steps leading to
a lot of duplicated stages in the tests.  A number of additional images can
be prepared using common steps, even if the ones used now have small
differences.

Therefore move the preparation of most of the guest images to the asset
build phase, where they can be done a single time for multiple test runs,
using a common preparation script.  We can even avoid making a copy of the
disk image for booting, by using qemu's -snapshot option.

A few of the distros (openSUSE and older Ubuntu) do need different steps.
For now we don't chage how they are run, they could possibly be handled
more like this in future.

32c5e05479 tests: Move distro image download to asset build makefile

all the downloads during the test asset build, then just clone them for

7bcc5930a6 Invoke specific qemu-system-* binaries
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).

c4d8a77512 tests: qemu-system-ppc64le isn't a thing
Several tests run pp64le guests using "qemu-system-ppc64le".  But, at the
system level there's no difference between ppc64 and ppc64le - it's the
same hardware, just placed into different endian modes by OS early boot
code.  Reflecting that, qemu only supplies a single "qemu-system-ppc64".

Some distros alias qemu-system-ppc64le to qemu-system-ppc64 (Debian does),
but it's best not to count on this (Fedora doesn't, for example).

25f515831c Makefile: Use $(BIN) and $(MANPAGES) variable to simplify several targets
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.

as a side effect of the pasta target.

ca0c33ae5b Tweak dhclient arguments for readability
A number of tests and examples use dhclient in both IPv4 and IPv6 modes.
We use "dhclient -6" for IPv6, but usually just "dhclient" for IPv4.  Add
an explicit "-4" argument to make it more clear and explicit.

In addition, when dhclient is run from within pasta it usually won't be
"real" root, and so will not have access to write the default global pid
file.  This results in a mostly harmless but irritating error:
    Can't create /var/run/dhclient.pid: Permission denied
We can avoid that by using the --no-pid flag to dhclient.

6e61b4040a test: Add distribution tests for several architectures and kernel versions
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.
