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.

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.

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.

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.

The top level listing control of which tests to run is in test/run, however
it uses the test() function which runs an entire directory of test files,
filtered by some criteria. This makes it awkward to narrow down to a
subset of tests when debugging a specific failure.
To make this easier, have test() take an explicit list of test files to
run, and have the caller in test/run handle the directory traversal. The
construct we use for this is pretty awkward to handle the fact that we're
in the source tree root directory rather than test/ at this point in
test/run. Later cleanups will improve that.

The test scripts support a "req" directive which requires one test script
to be run before another. It's implemented by doing a topological sort
based on these directives in the runner scripts, which is about as awkward
as you'd expect in Bourne shell.
It turns out we only use this functionality in one place - to make the
"make install" test run after the plain "make" test. We also already have
a simpler way of making sure tests run in a specific order: just put them
into the same test script file.
So, remove support for the "req" directive and just fold the build/all and
build/install test scripts together.

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.

Move the download of mbuto and using it to create a sample initramfs to
the asset build makefile, rather than embedding it in the test scripts
themselves.
The two_guests tests used to use two separate copies of the mbuto
image. As an initramfs the mbuto image is strictly readonly though,
so that's not necessary. So, also use the same image for both guests.

A number of passt/pasta testcases have initial steps which are just about
building images or other assets we need for the test proper. Repeating
these for each test run can be quite costly.
This patch makes a start on moving this sort of test asset building to
a separate phase before running the tests proper. For now just add a
Makefile to handle the asset building (although it doesn't build
anything yet), and make the path where we'll be building the assets
available to the tests.

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).

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).

David reports that dhclient-script(8) on Fedora needs a number of
binaries that are not included in PROGS of the current mbuto profile,
and we would also need to include hostnamectl(1) there, which will
fail without a systemd init.
Embed a minimal script for dhclient(8) in the profile itself, written
to /sbin/dhclient-script at boot, to just check what we need to check
out of DHCP and DHCPv6 functionality.
While at it, drop busybox and logger from PROGS, as we don't need them,
and add hostname(1). While DHCP option 12 isn't supported yet by the
DHCP implementation in passt, we should probably add it soon.
Note: owing to the simplicity of this script, we now need to bring up
the interface before starting dhclient: add this in test scripts where
it's not the case yet.

A number of the testcases use options specific the OpenBSD version of
netcat. That's available in Debian, but not easily available in Fedora.
Switch the pasta tests to using the nmap version of netcat (a.k.a. ncat).
This is easily available in both Debian and Fedora, and appears to be a
bit more modern and maintained as well.
ncat generally requires explicit listen addresses (which is good for
clarity anywhere). Its default options appear to remove the need for the
-N and -q options.

For some reason, the passt/pasta tests and examples use dhclient for
DHCPv6, but in most cases use udhcpc for DHCPv4. Change it to use dhclient
for both DHCPv4 and DHCPv6. This means one less tool we need for testing,
plus dhclient is easily available on Fedora whereas udhcpc is not.
Note that the passt tests still rely on udhcpc indirectly because mbuto
wants to put it into the guest images it generates.

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.

distro/fedora contains two versions of the basic tests, used for different
Fedora versions. One uses explicit listening address for netcat in some
extra places, the other does not. Apparently the older netcat versions
didn't require the explicit addresses. Not supplying addresses doesn't
test anything useful though, just a detail in netcat's behaviour. So,
it's cleaner to just always supply explicit addresses.
In addition, we're explicitly expecting the nmap version of ncat, also
known as "ncat". So, it's more explicit what we're after if we invoke it
via that name rather than "nc", which will go via an /etc/alternatives
link.

When we use pane_wait to wait for a command issued to a tmux pane to finish
we have no idea whether the command succeeded or not. This means that the
test scripts can keep running long after the point something vital has
failed, making it difficult to work out what went wrong.
Add a new pane_status command that checks for success of the issued command
and use it in most places instead of pane_wait. We still need explicit
pane_wait where we're gathering explicit output with pane_parse, because
the way we check the status with 'echo $?' means we lose track of that
output.

Most commands issued during the testing scripts aren't explicitly checked
for errors. Therefore, if they fail, the shell will just keep on
executing. This makes it difficult to figure out where things started
going wrong if things fall over.
Run the whole script with the set -e mode so that it will exit in the case
of any (unchecked) failing command. To make this work we do need to add
explicit checks / fallbacks for some commands which we expect to fail.

pane_parse() attempts to grab the output from the last command issued
into a tmux pane. It strips out control characters using tr, which in
particular includes the final \r\n. However, this won't fully strip
out terminal escape sequences. In particular this breaks if the shell
in the pane is bash, with enable-bracketed-paste enabled in readline.
That issues terminal sequences to enable and disable bracketed paste
mode around every shell prompt.
We can work around this because these escapes are followed by a \r
(CR). More generally, it seems reasonable to assume that any terminal
shenanigans followed by a CR, but not an LF is supposed to be hidden.
So, use sed to strip everything before the second last CR. We still
need the tr to remove the final \r\n from the string (sed processes a
line at a time, and doesn't consider the CRLF part of the buffer it's
processing).

run_term() uses tmux set-option -g to globally set the default shell.
Unfortunately this hits a chicken-and-egg problem that's common with many
of tmux's session options. If there isn't already a tmux server running,
we can't connect to set the option. If we attempt this after starting our
session (and therefore the server), then the session will already be
started with the previous default shell.
In any case it's not a good idea to set tmux global options, since that
might interfere with whatever else the user is doing in tmux. So, instead
set the default-shell option locally to the session after starting it. To
make sure we get the right shell for our initial script, explicitly invoke
/bin/sh to interpret it.

The semantics of tmux's update-environment option are a bit confusing.
It says it means the given variables are copied into the session
environment from the source environment, but it's not entirely clear
what the "source" environment means.
From my experimentation it appeast to be the environment from which
the tmux *server* is launched, not the one issuing the 'new-session'
command. That makes it pretty much useles, certainly in our case where
we have no way of knowing if the user has pre-existing tmux sessions.
Instead use the new-session -e option to explicitly pass in the variables
we want to propagate.

Build-time selection of AVX2 flags and routines is not practical for
distributions, but limiting AVX2 usage to checksum routines with
specific run-time detection doesn't allow for easy performance gains
from auto-vectorisation of batched packet handling routines.
For x86_64, build non-AVX2 and AVX2 binaries, and implement a simple
wrapper replacing the current executable with the AVX2 build if it's
available, and if AVX2 is supported by the current CPU.
