    Introduce virNodeAllocPages
    
    A long time ago in a galaxy far, far away it has been decided
    that libvirt will manage not only domains but host as well. And
    with my latest work on qemu driver supporting huge pages, we miss
    the cherry on top: an API to allocate huge pages on the run.
    Currently users are forced to log into the host and adjust the
    huge pages pool themselves.  However, with this API the problem
    is gone - they can both size up and size down the pool.
