When a checkpoint is redefined without providing the domain XML, we
might end up with a definition where the per-disk bitmap name is not
set. Trying to delete such checkpoint would lead to a crash.
Refuse such deletion.

Skip the lossy conversion to legacy commandline arguments by using the
JSON props directly when -object is QAPIfied. This avoids issues with
conversion of bitmaps and also allows validation of the generated JSON
against the QMP schema in the tests.
Since the new approach is triggered by a qemu capability the code
from 'virQEMUBuildObjectCommandlineFromJSON' in util/virqemu.c was moved
to 'qemuBuildObjectCommandlineFromJSON' in qemu/qemu_command.c which has
the virQEMUCaps type.

Starting from qemu-6.0 the parameters of -object/object-add are formally
described by the QAPI schema. Additionally this changes the nesting of
the properties as the 'props' nested object will be flattened to the
parent.
We'll need to detect whether qemu switched to this new approach to
generate the objects with proper nesting and also allow testing.

When the backup job is terminated normally the security label is
restored by the blockjob finishing handler.
If the VM dies or is destroyed that wouldn't happen as the blockjob
handler wouldn't be called.
Restore the security label on disk store where we remember that the job
was running at the point when 'qemuBackupJobTerminate' was called.
Not resetting the security label means that we also leak the xattr
attributes remembering the label which prevents any further use of the
file, which is a problem for block devices.
This also requires that the call to 'qemuBackupJobTerminate' from
'qemuProcessStop' happens only after 'vm->pid' was reset as otherwise
the security subdrivers attempt to enter the process namespace which
fails if the process isn't running any more.
