Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>

Use the guest's own p2m table instead of xc_get_pfn_list(), which
cannot handle PFNs with no MFN.
Dump a zeroed page for PFNs with no MFN.
Clearly deprecate xc_get_pfn_list().
Do not include a P2M table with HVM domains.
Refuse to dump HVM until we can map its pages with PFNs.
