[libvirt] [PATCH v1 09/14] virDomainDeviceInfoCheckABIStability: Check for alias too

[Michal Privoznik]

Since we'll be passing user's input onto qemu command line, we
have to make sure aliases don't change during migration and all
the other places where ABI is checked. Aliases are part of ABI
now.
