24793bdf28 qemumonitorjsontest: Add a last-resort warning if object-add/device_add are QAPIfied
When netdev-add was qapified it took us by surprise and we had to
scramble to fix the internals to format conformant monitor arguments.

Add a last-resort early warning system if this happens to object-add or
device_add. Hopefully qemu developers notify us sooner than this.

ee247e1d3f Use g_strfeev instead of virStringFreeList
Both accept a NULL value gracefully and virStringFreeList
does not zero the pointer afterwards, so a straight replace

add3607ea8 qemumonitorjsontest: Mark recently deprecated migration command in our tests
"migrate_set_downtime", "migrate_set_speed", and
"query-migrate-cache-size" were marked as deprecated in the QMP schema
in qemu 5.0. Since libvirt still actively uses them we must not mark
them as okay to be missing, but still mark them as deprecated, so that
we can add tests for deprecated commands.

The replacement of the command usage in libvirt is tracked by:
