[libvirt] [PATCH v2 00/31] qemu: Add support for unavailable-features

[Jiri Denemark]

QEMU 2.8.0 adds support for unavailable-features in
query-cpu-definitions reply. The unavailable-features array lists CPU
features which prevent a corresponding CPU model from being usable on
current host. It can only be used when all the unavailable features are
disabled. Empty array means the CPU model can be used without
modifications.

Changes in v2:
- many; the way we probe QEMU was rewritten so that we probe both KVM
  and TCG capabilities and store them separately whenever we expect them
  to be different

Big thanks to Andrea Bolognani for providing the updated replies data
from aarch64 and ppc64le machines.
