    Add support for HAP feature to xen drivers
    
    xen-unstable c/s 16931 introduced a per-domain setting for hvm
    guests to enable/disable hardware assisted paging.  If disabled,
    software techniques such as shadow page tables are used.  If enabled,
    and the feature exists in underlying hardware, hardware support for
    paging is used.
    
    This provides implementation for mapping HAP setting to/from
    domxml/native formats in xen drivers.
