We are going to support non-PCI devices soon. For this we need to split
the generic GuestDiskAddress and GuestDiskAddressList memory allocation
and list chaining into a separate function first.

From: Thomas Huth <thuth@redhat.com>
The libudev-related code is independent from the other pci-related code
and can be re-used for non-pci devices (like ccw devices on s390x). Thus
move this part to the generic function.

From: Tomáš Golembiovský <tgolembi@redhat.com>
Add command for reporting devices on Windows guest. The intent is not so
much to report the devices but more importantly the driver (and its
version) that is assigned to the device. This gives caller the
information whether VirtIO drivers are installed and/or whether
inadequate driver is used on a device (e.g. QXL device with base VGA
driver).
Example:
[
{
"driver-date": "2019-08-12",
"driver-name": "Red Hat VirtIO SCSI controller",
"driver-version": "100.80.104.17300",
"address": {
"type": "pci",
"data": {
"device-id": 4162,
"vendor-id": 6900
}
}
},
...
