The qemuMonitorTestAddErrorResponse() function is a printf-like
function. But the annotation was mistakenly done in .c file
instead of corresponding .h file rendering the annotation
ineffective. Move the annotation to the header file.

While __attribute((sentinel)) (exposed by glib under
G_GNUC_NULL_TERMINATED macro) is a gcc extension, it's supported
by clang too. It's already being used throughout our code but
some functions that take variadic arguments and expect NULL at
the end were lacking such annotation. Fill them in.
After this, there are still some functions left untouched because
they expect a different sentinel than NULL. Unfortunately, glib
does not provide macro for different sentinels. We may come up
with our own, but let's save that for future work.

We never release the reference on the GSource created for
interrupting the main loop, nor do we remove it from the
main context if our thread is woken up prior to the wakeup
callback firing.
This can result in a leak of GSource objects, along with an
ever growing list of GSources attached to the main context,
which will gradually slow down execution of the loop, as
several operations are O(N) for the number of attached GSource
objects.

When attempting to run:
libvirt.git/_build # ./run --selinux ./src/libvirtd
the following error is thrown:
Refusing to change selinux context of file './src/libvirtd' outside build directory
which is obviously wrong. The problem is 'being inside of build
directory' is detected by simple progpath.startswith(builddir).
While builddir is an absolute path, progpath isn't necessarily.
And while looking into the code, I've noticed chcon() function
accessing variable outside its scope when printing out the path
it's working on.

When the 'pages' job is configured to run 'on_success' it's skipped if
any other pipeline fails. This is bad in cases such as if an external
service runs out of CI minutes as the web stops being updated.
Since the 'artifacts' of the 'website_job' are generated only if that

When hot-plugging a FS device with un-assigned address with a bootindex
the recently-added validation check would fail as validation on hotplug
is done prior to address assignment.
To fix this problem we can simply relax the check to also pass on _NONE
addresses. Unsupported configurations will still be caught as previous
commit re-checks the definition after address assignment prior to
hotplug.

When removing rotated log files, their name is matched against a
regex (@log_regex) and if they contain '.N' suffix the 'N' is
then parsed into an integer. Well, due to a bug in
virLogCleanerParseFilename() this is not how the code works. If
the suffix isn't found then g_match_info_fetch() returns an empty
string instead of NULL which then makes str2int parsing fail.
Just check for this case before parsing the string.

In one of my recent commits, I've introduced
virDomainInterfaceClearQoS() which is a helper that either calls
virNetDevBandwidthClear() ('tc' implementation) or
virNetDevOpenvswitchInterfaceClearQos() (for ovs ifaces). But I
made a micro optimization which leads to a bug: the function
checks whether passed iface has any QoS set and returns early if
it has none. In majority of cases this is right thing to do, but
when removing QoS on virDomainUpdateDeviceFlags() this is
problematic. The new definition (passed as argument to
virDomainInterfaceClearQoS()) contains no QoS (because user
requested its removal) and thus instead of removing the old QoS
setting nothing is done.
Fortunately, the fix is simple - pass olddev which contains the
old QoS setting.

The current implementation requires users to configure the
preference as such:
-Dfirewall_backend_default_1=iptables
-Dfirewall_backend_default_2=nftables
In addition to being more verbose than one would hope, there
are several things that could go wrong.
First of all, meson performs no validation on the provided
values, so mistakes will only be caught by the compiler.
Additionally, it's entirely possible to provide nonsensical
combinations, such as repeating the same value twice.
Change things so that the preference can now be configured
as such:
-Dfirewall_backend_priority=iptables,nftables
Checks have been added to prevent invalid values from being
accepted.

Add test data based on qemu commit v9.0.0-995-g60b54b67c6 on x86_64
Comparison to previous release:
Feature additions:
- 9.1 machine type added
- 'SierraForest' cpu type added
- 'SapphireRapids-v3-x86_64-cpu' added
- 'VFIO_MIGRATION' event added (and corresponding 'migration-events'
bool for the device
- 'exit-on-error' argument for 'migrate-incoming' added
- 'sev-guest' gained 'legacy-vm-type' boolean
- cpu topology added 'module' fields
- 'compat-props' argument 'query-machines' added
- 'deprecated-props' argument for 'query-cpu-model-expansion' added
Deprecated removals:
- legacy non-shared-storage migration fully removed (config/stats)
- legacy migration compression fully removed
- RDMA support removed
- dropped 'nios2' field type from 'query-cpus-fast' return data
Note that this dump was done on a newer kernel version which resulted in
the 'pcommit' feature being removed from the few test cases which depend
on the real CPU flag dump.

This can happen only for cmdComplete() in interactive mode (which
I'm still not convinced is any useful for users and whether we
should support it). Anyway, running plain 'complete' command with
no additional arguments boils down to @text being NULL in
vshReadlineParse() which handles the case just right but is then
subsequently passed to vshCompleterFilter() which isn't prepared
for this case.

Problem with readline is its API. It's basically a bunch of
global variables with no clear dependencies between them. In this
specific case that I'm seeing: in interactive mode the
cmdComplete() causes instant crash of virsh/virt-admin:
==27999== Invalid write of size 1
==27999== at 0x516EF71: _rl_init_line_state (readline.c:742)
==27999== by 0x5170054: rl_initialize (readline.c:1192)
==27999== by 0x516E5E4: readline (readline.c:379)
==27999== by 0x1B7024: vshReadline (vsh.c:3048)
==27999== by 0x140DCF: main (virsh.c:905)
==27999== Address 0x0 is not stack'd, malloc'd or (recently) free'd
This is because readline keeps a copy of pointer to
rl_line_buffer and the moment cmdComplete() returns and readline
takes over, it accesses the copy which is now a dangling pointer.
To fix this, just keep the original state of rl_line_buffer and
restore it.

iifname/oifname need to lookup the string that contains the name of
the interface each time a packet is checked, while iif/oif compare the
ifindex of the interface, which is included directly in the
packet. Conveniently, the rule is created using the *name* of the
interface (which gets converted to ifindex as the rule is added), so
no extra work is required other than changing the commandline option.
If it was the case that the interface could be deleted and re-added
during the life of the rule, we would have to use Xifname (since
deleting and re-adding the interface would result in ifindex
changing), but for our uses this never happens, so Xif works for us,
and undoubtedly improves performance by at least 0.0000001%.

Commit 91f4ebbac8 (v10.0.0-185-g91f4ebbac8)
changed the return value of virSocketSendFD() from 0 to 1 on success.
Unfortunately in 'virFileOpenForked' the return value was used to report
the error back to the main process from the fork'd child. As process
return codes are positive only, the code negates the value of 'ret' and
reports it. This resulted in the parent thinking the process exited with
failure:
# virsh save avocado-vt-vm1 /mnt/save
error: Failed to save domain 'avocado-vt-vm1' to /mnt/save
error: Error from child process creating '/mnt/save': Unknown error 255
This error reproduces on NFS mounts with 'root_squash' enabled. I've
also observed it in one specific migration case when root_squash NFS is
used with following error:
Failed to open file '/var/lib/libvirt/images/alpine.qcow2': Unknown error 255'
To fix the issue the code is refactored so that it doesn't actually
touch the 'ret' variable needlessly and assigns to it only on failure
cases, which prevents the '1' to be propagated to the parent process as
'255' after negating and storing in the process return code.
