Subject: [PATCH 28/60] VSMS: Support for device addresses

This allows to define KVM guests with persistent device addresses
for disks and network interfaces.
The new function rasd_to_device_address extracts the address
properties from the disk or network RASD and fills the
device_address sub-structure of the affected virt_device.
