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.

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).

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.

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.

A number of individual test cases use '*out' commands to check for success
of specific commands they've issued. Now that the test harness is testing
for success of all issued commands as a matter of course, we no longer need
to do this.

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.
