    xenapi: simplify PV vs HVM selection logic
    
    The logic to inspect a disk to determine if an image is PV or HVM has
    been removed. This change follows on from that simplification.
    
    As before, if I user wants to use PV mode, or HVM mode, then can set
    vm_mode=xen or vm_mode=hvm, respectively. This will override any other
    way of selecting the mode.
    
    For consistency, we now check the os_type to be either windows or linux,
    which, without vm_mode, chooses HVM or XEN mode respectively.
    
    For backwards compatibility, all VHD and DISK type images default to
    vm_mode=xen.
    
    In all other cases, we default to HVM, as this is the safest option
    that works with most images.
