Host Numa information in dom0
'xm info' command now also gives the cpu topology & host numa
information. This will be later used to build guest numa support. The
patch basically changes physinfo sysctl, and adds topology_info &
numa_info sysctls, and also changes the python & libxc code
accordingly.
