[libvirt] [PATCH v3 14/28] cpu_x86: Introduce virCPUx86DataSetSignature

[Jiri Denemark]

The API is useful for creating virCPUData in a hypervisor driver from
data we got by querying the hypervisor.

Notes:
    Version 3:
    - ACKed in v2
    - better commit message
    - #include "cpu/cpu_x86.h" in qemu_capabilities.c moved to the patch
      which makes use of the API
    
    Version 2:
    - no change
