[Libvir] NUMA topology calls

[beth kon <eak us ibm com>]

Daniel,

We agreed that xenHypervisorGetCapabilities will call a xend_internal.c 
function to get the topology through xend.
Was your intent to extend xenDaemonNodeGetInfo or have a new function, 
such as xenDaemonNodeGetTopology?  I assumed a new function would be 
cleaner, but you didn't include such a function in your patch so I'm not 
sure if you had some other idea.
