    tools/misc: don't include xg_save_restore.h from xen-mfndump.c
    
    xen-mfndump.c is including the libxc private header xg_save_restore.h.
    Avoid that by moving the definition of is_mapped() to xen-mfndump.c
    (it is used there only) and by duplicating the definition of
    M2P_SIZE() in xen-mfndump.c.
