This info can be useful to filter devices visible
to mgmt clients so that they won't see devices that
unsafe/not meaningful to pass thru.
Provide class info the way it is provided by udev or
kernel that is as single 6-digit hexadecimal.
Class element is not optional. I guess this should not
break users that use virNodeDeviceCreateXML because
they probably specify only scsi_host capability on
input and then node device driver gets other capabilities
from udev after device appeared.
HAL driver does not get support for the new element in
this patch.

A PCI device can be associated with a specific NUMA node. Later, when
a guest is pinned to one NUMA node the PCI device can be assigned on
different NUMA node. This makes DMA transfers travel across nodes and
thus results in suboptimal performance. We should expose the NUMA node
locality for PCI devices so management applications can make better
decisions.

Add a test to check node device XML parsing by first parsing
the XML, then re-formatting as XML and finally comparing the
resulting XML to the original XML.
