[PATCH v4 for v7.6.0 00/14] Introduce virtio-mem <memory/> model

[Michal Privoznik]

v4 of:

https://listman.redhat.com/archives/libvir-list/2021-April/msg01138.html

diff to v3:
- Rebased code on the top of master
- Tried to work in all Peter's review suggestions
- Fixed a bug where adjusting <requested/> was viewed as hotplug of new
  <memory/> by XML validator and thus if <maxMemory/> was close enough to
  <currentMemory/> the validator reported an error (this was reported by
  David).
