We were testing the arguments that were being passed to qemu when a disk

itself were not testable. This adds a test to ensure that we're invoking
nbdkit correctly for various disk source definitions.

Apparently we've only had it because the -[ao] options weren't portable
at the time, but according to
https://pubs.opengroup.org/onlinepubs/9699919799/utilities/test.html
both are defined in POSIX.1-2017 revision which is old enough for all
our supported platforms to have adopted it already, so we can drop the
check. However, the above has also marked -[ao] as obsolescent stating
that:
"[OB] Obsolescent
The functionality described may be removed in a future version of
this volume of POSIX.1-2017. Strictly Conforming POSIX Applications
and Strictly Conforming XSI Applications shall not use obsolescent
features."
It is however unlikely that the shell implementations would drop
support for -[ao] despite POSIX potentially removing them.

Okay, this is a shortcut. Our coding style says that error
messages are exempt from '80 chars long lines' rule. But in the
very same paragraph it is said that all error messages need to be
marked for translation (as they might be presented to user).
Therefore, the syntax-check rule can check if _("...") is
formatted on one line. With exception of _("...\n" ...) (e.g.
various outputs from helper binaries like leaseshelper,
sshhelper, or daemons like lockd, logd). I believe nobody would
chose a substring that contains '\n' for git grep-ping the error
message.

Introduce a test that checks newly introduced virAcpi module.

Since all messages marked for translation contain permutable format
strings, we can add checks for enforcing them.
The syntax check does not catch all cases as it only checks format
strings between _(" and the first ". In other words messages where \"
appears before the first format string or multi-line messages where the
first format strings is not in the first line will not be checked. On
the other hand, it's run automatically by "meson test".
check-pot.py python script will detect all incorrect format strings, but
it's not as easy to use as it requires libvirt.pot to be regenerated and
this does not happen during a standard build. The following steps are
needed to check messages with check-pot.py:
meson compile libvirt-pot-dep
meson compile libvirt-pot
meson compile libvirt-pot-check
Don't forget to revert changes to libvirt.pot if you run these commands
locally as we don't want each patch series to update libvirt.pot.
Shell scripts (tools/libvirt-guests.sh.in is the only one currently)
need to be exempt from this check as shell's printf function does not
understand the permutable format strings.

When a VirtualBox API fails it produced an exception. Until now,
we did not have correct APIs wired up to get the exception and
its error message. Thus, we were left with plain:
virReportError("virtualbox API failed, rc=%08x", rc);
This is not very user friendly because those rc values are hard
to parse (e.g. some values are defined as a sum of a base value
and some other value) and also it expects users to know where to
look.
But now that we have all machinery needed for querying
exceptions, vboxReportError() can be introduced. The aim is to
query VirtualBox exceptions and append them after the error
message we intent to report. If the exception can't be queried
successfully, this behaves exactly like virReportError().

Libvirt provides QMP passthrough APIs for the QEMU driver and these are
exposed in virsh. It is not especially pleasant, however, using the raw
QMP JSON syntax. QEMU has a tool 'qmp-shell' which can speak QMP and
exposes a human friendly interactive shell. It is not possible to use
this with libvirt managed guest, however, since only one client can
attach to the QMP socket at any point in time. While it would be
possible to configure a second QMP socket for a VM, it may not be
an known requirement at the time the guest is provisioned.
The virt-qmp-proxy tool aims to solve this problem. It opens a UNIX
socket and listens for incoming client connections, speaking QMP on
the connected socket. It will forward any QMP commands received onto
the running libvirt QEMU guest, and forward any replies back to the
QMP client. It will also forward back events.
$ virsh start demo
$ virt-qmp-proxy demo demo.qmp &
$ qmp-shell demo.qmp
Welcome to the QMP low-level shell!
Connected to QEMU 6.2.0
(QEMU) query-kvm
{
"return": {
"enabled": true,
"present": true
}
}
Note this tool of course has the same risks as the raw libvirt
QMP passthrough. It is safe to run query commands to fetch information
but commands which change the QEMU state risk disrupting libvirt's
management of QEMU, potentially resulting in data loss/corruption in
the worst case. Any use of this tool will cause the guest to be marked
as tainted as an warning that it could be in an unexpected state.
Since this tool introduces a python dependency it is not desirable
to include it in any of the existing RPMs in libvirt. This tool is
also QEMU specific, so isn't appropriate to bundle with the generic
tools. Thus a new RPM is introduced 'libvirt-clients-qemu', to
contain additional QEMU specific tools, with extra external deps.

There are some tools that convert hostname to lowercase before
resolving it (e.g. ssh). In a way it makes sense because DNS is
case insensitive and in case of ssh the lowercase version is then
used to find matching record in its config file. However, our NSS
module performs case sensitive comparison, which makes it useless
with ssh. Just consider a machine named FooBar.
Therefore, switch to case insensitive string comparison.

Commit 8beb7fdd0e changed the handling of POTFILES so that it
could cope with files being located in either the source or build

respectively at the beginning of each line, and then converting
them back to the actual values when generating POTFILES from
POTFILES.in.
Later, commit c6a0d3ff8b started passing --directory to
xgettext, which resulted in the tool being able to locate files
regardless of whether they are in the source or build directory.
However, @SRCDIR@ and @BUILDDIR@ were still added to POTFILES.in
only to be stripped when generating POTFILES.

There is one exception: the 'conf' object, where we store values

object is not feasible for two reasons: first of all, replacing
