Michal Privoznik 35f1095e12 virnuma: Introduce pages helpers 
For future work we need two functions that fetches total number of
pages and number of free pages for given NUMA node and page size
(virNumaGetPageInfo()).

Then we need to learn pages of what sizes are supported on given node
(virNumaGetPages()).

Note that system page size is disabled at the moment as there's one
issue connected. If you have a NUMA node with huge pages allocated the
kernel would return the normal size of memory for that node. It
basically ignores the fact that huge pages steal size from the system
memory. Until we resolve this, it's safer to not confuse users and
hence not report any system pages yet.

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
