Our entry point for syntax-check rules is meson, which calls
to each of them specifically; additionally, we have the 'all'
target that warns users who try to use make directly.
The 'syntax-check' target is not used by anything, and in fact
it couldn't be even if one tried: its availability depends on
the $(_gl-Makefile) variable, which in our case is never
defined.

The most notable change is the new 'sc_unportable_grep_q' rule.
While importing it from gnulib, the rule has been tweaked
slightly by adding superflous quotes so that syntax-check.mk
itself doesn't trip it. This is similar to the tricks employed
for the 'sc_prohibit_close' and 'sc_copyright_usage' rules,

While glibc provides qsort(), which usually is just a mergesort,
until sorting arrays so huge that temporary array used by
mergesort would not fit into physical memory (which in our case
is never), we are not guaranteed it'll use mergesort. The
advantage of mergesort is clear - it's stable. IOW, if we have an
array of values parsed from XML, qsort() it and produce some
output based on those values, we can then compare the output with
some expected output, line by line.
But with newer glibc this is all history. After [1], qsort() is
no longer mergesort but introsort instead, which is not stable.
This is suboptimal, because in some cases we want to preserve
order of equal items. For instance, in ebiptablesApplyNewRules(),
nwfilter rules are sorted by their priority. But if two rules
have the same priority, we want to keep them in the order they
appear in the XML. Since it's hard/needless work to identify
places where stable or unstable sorting is needed, let's just
play it safe and use stable sorting everywhere.
Fortunately, glib provides g_qsort_with_data() which indeed
implement mergesort and it's a drop in replacement for qsort(),
almost. It accepts fifth argument (pointer to opaque data), that
is passed to comparator function, which then accepts three
arguments.
We have to keep one occurance of qsort() though - in NSS module
which deliberately does not link with glib.

This implements a C code generator that emits code that is

key differences are:
- Skip inlining of calls for struct fields
- Skip K&R style function prototypes in headers
- Use int64_t instead of quad_t for OS portability
- Saner whitespace / indentation
The tests/demo.c and tests/demo.h files were created using

above.

Currently, passing -Dtests=disabled only disables a subset of
tests: those that are written in C and thus require compilation.
Other tests, such as the syntax-check ones and those that are
implemented as scripts, are always enabled.
There's a potentially dangerous consequence of this behavior:
when tests are disabled, 'meson test' will succeed as if they
had been enabled. No indication of this will be shown, so the
user will likely make the reasonable assumption that everything
is fine when in fact the significantly reduced coverage might
be hiding failures.
To solve this issues, disable *all* tests when asked to do so,
and inject an intentionally failing test to ensure that 'meson
test' doesn't succeed.

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.

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.
