Due to historical reasons we allow users to redefine an existing
snapshot without providing the domain definition which would correspond
to it. In such case we'd use the domain definition from the snapshot
that is being redefined.
To prevent callers from doing complex moving of the domain definition
object back and forth between the snapshot definitions we can add an
argument to virDomainSnapshotAlignDisks which will allow us to pass in
the alternate definition if the one from the snapshot is missing.

'require_match' set to true is only needed for internal snapshots taken
by hypervisors (qemu) which don't have a way to control which disks take
part in the snapshot (savevm).
To de-clutter callers we can change the argument to mean 'this code path
requires uniform snapshot for internal snapshots'.
Change the argument and fix the callers. For now all callers pass 'true'
but any new hypervisor or even usage in qemu is not going to share the
limitation.

External snapshot with memory is created without using the
VIR_DOMAIN_SNAPSHOT_CREATE_DISK_ONLY flag, but rather with properly
configuring the XML. When redefining the code should be checking the
same thing as by definition an external snapshot with memory is not a

Remove error handling from the call to 'virDomainMomentObjNew' as it
can't return NULL and replace 'virHashAddEntry' by 'g_hash_table_insert'
as we've already checked that snapshot with such name doesn't exist in
the hash table. This removes handling for two impossible errors.

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.

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.

which makes sense, because "cflags" is not one of the variables
reported by

$ pkg-config --variable=cflags yajl

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.
