Commit f4aae9726d factored out the snapshot redefinition code into a
separate function, but didn't account for the fact that the code is
consuming the reference to the snapshot definition and by moving the
code away the caller (qemuSnapshotCreateXML) now frees the definition
which didn't happen before as we cleared the pointer.
Fix it by increasing the reference locally. Later patches will refactor
the code so that it's more obvious what's happening.

'def' is commonly used to refer to domain definition. Most of the

Our approach to snapshots without metadata was to insert them to the
snapshot list and then later remove them from the list when the flag is
present.
This quirky logic was broken in a recent refactor of the snapshot code
causing that the snapshot stayed inserted in the snapshot list.
Recent refactor of the snapshot code didn't faithfully relocate this
logic to the new function.
Rather than attempting to restore the quirky logic of adding and then
removing the object, don't add the snapshot into the list at all when
the user doesn't want metadata.
We achieve this by creating a temporary 'virDomainMomentObj' wrapper
which is not inserted into the list and using that instead of calling
virDomainSnapshotAssignDef.

Meson reports
WARNING: pkgconfig variable 'cflags' not defined for dependency yajl.
which makes sense, because "cflags" is not one of the variables
reported by
$ pkg-config --print-variables yajl
and
$ pkg-config --variable=cflags yajl
doesn't work either.
The breakage was introduced when we switched from calling
pkg-config directly to using get_pkgconfig_variable() in 7.5.0
and, somehow, it went undetected until now.
Use "includedir", which is a proper pkg-config variable,
instead.

When -device is configured via JSON a bug [1] is triggered in qemu were
the DEVICE_DELETED event for the removal of the device frontend is no
longer delivered to libvirt. Without the DEVICE_DELETED event we don't
remove the corresponding entries in the VM XML.
Until qemu will be fixed we must stop using the JSON syntax for -device.
This patch removes the detection of the capability. The capability is
used only during startup of a fresh VM so we don't need to consider any
compaitibility steps for existing VMs.
For users who wish to use 'libvirt-7.9' and 'libvirt-7.10' with
'qemu-6.2' there are two possible workarounds:
- filter out the 'device.json' qemu capability '/etc/libvirt/qemu.conf':
capability_filters = [ "device.json" ]
- filter out the 'device.json' qemu capability via qemu namespace XML:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
[...]
<qemu:capabilities>
<qemu:del capability='device.json'/>
</qemu:capabilities>
</domain>
We must never again use the same capability name as we are now
instructing users to filter it as a workaround so once qemu is fixed
we'll need to pick a new capability value for it.

We don't usually provide manual pages for internal tools,
but in the case of virt-ssh-helper the command is installed
inside the default $PATH and so it's likely that the user
will stumble upon it by using the shell's completion feature
when invoking another virt-* command, which makes it a good
idea to provide at least a minimal manual page.

Until now we did 2 weird things when inserting the qemuCaps used for
individual test cases into the capability cache:
1) we inserted the same caps for all emulators
2) we always (expensively) copied them
Now when real capabilities are used we don't touch them at all just
simply inser them. This allows us one big optimization, by trading a
copy for just a virObjectRef as we can borrow the caps object to the
cache.
For fake caps we still copy them as we insert the fake machine types
into them, but second big optimization is to insert the capabilities
only for the architecture they belong to.
Additionally this commit also ensures that all other entries in the
cache for the binary are poisoned by empty caps so that it's obvious
that the test is doing the right thing.
Apart from this making actually more sense this shaves off more than 40%
of runtime from qemuxml2argvtest.

As demonstrated by the qemuxml2xmltest DO_TEST_CAPS_LATEST data based on
the 'x86-kvm-32-on-64' test case the post parse CPU selection code which
fills in the CPU into the definition does not have exactly the same
logic as we used to have when the cpu model was picked when formatting
the commandline.
Change the qemuxml2argv test to use DO_TEST_CAPS_LATEST too as it
doesn't really make sense to test this on fake data.
In addition to 'latest' versions, this also adds second invocation
locked to qemu-4.1.0 which demonstrates the old behaviour.

Fake capabilities are inserted twice, as in a few tests the architecture

Since we already know which architecture will be picked we don't need to
be adding the capabilities twice.
