report how much memory a domain has on each NUMA node

Going all the way from an hypercall to the `xl' sub-command (via libxl and libxc interfaces, of course).

For the following domains:

root@Zhaman:~# xl list -n
Name                                        ID   Mem VCPUs      State   Time(s) NODE Affinity
Domain-0                                     0   511    16     r-----      29.3 all
vm-test                                      1  1024     2     -b----       6.6 0

The output looks like this:

root@Zhaman:~# xl numainfo 0
NODE Affinity: all
Memory:
  Node 0: 251208 Kb
  Node 1: 272820 Kb

root@Zhaman:~# xl numainfo 1
NODE Affinity: 0
Memory:
  Node 0: 1048576 Kb
