[PATCH QEMU HCI-8.1 00/21] vfio: support qemu-update with passed through GPU's and vGPU's #VSTOR-103860

[Andrey Drobyshev <andrey.drobyshev@virtuozzo.com>]

Patches 1-13 are pure upstream commits backports.

Patches 14-15 are bug fixes, upstreamable.
Patches 16-17 are VFIO CPR migration support, upstreamable.

Patches 18-21 are VZ downstream qemu-update support.

Tested on (bg-sdc2-e18-15.aci.vzint.dev, bg-sdc2-e18-17.aci.vzint.dev)
stand with NVIDIA GPU's and vGPU's.
