This series address the same issue as seemingly abandomed patch series [1].
Implementation is written from scratch however as I don't see need to introduce
new flags for the purpose of this patch series. However I read John's comments
and addressed them where applied. The option for not reverting inactive config
in case of restoring active persistent domain that Jiri suggested in [2] is new
functionality actually and is left for future work.

The purpuse of patch series is described in patch 3
"qemu: snapshot: save/restore inactive persistent config":

    In case of active persistent domain snapshot metadata is
    not complete. We save only active configuration and on
    restore use it both for active and inactive configuration.
    Let's fix it and save and restore both in this case.
