    libxl: Do not trust frontend for disk eject event
    
    Use the /libxl path for interpreting disk eject watch events: do not
    read the backend path out of the frontend.  Instead, use the version
    in /libxl.  That avoids us relying on the guest-modifiable
    $frontend/backend pointer.
    
    To implement this we store the path
      /libxl/$guest/device/vbd/$devid/backend
    in the evgen structure.

    libxl: Do not trust frontend in libxl__devices_destroy
    
    We need to enumerate the devices we have provided to a domain, without
    trusting the guest-writeable (or, at least, guest-deletable) frontend
    paths.
    
    Instead, enumerate via, and read the backend path from, /libxl.
    
    The console /libxl path is regular, so the special case for console 0
    is not relevant any more: /libxl/GUEST/device/console/0 will be found,
    and then libxl__device_destroy will DTRT to the right frontend path.

    libxl: Record backend/frontend paths in /libxl/$DOMID
    
    This gives us a record of all the backends we have set up for a
    domain, which is separate from the frontends in
      /local/domain/$DOMID/device.
    
    In particular:
    
    1. A guest has write permission for the frontend path:
      /local/domain/$DOMID/device/$KIND/$DEVID
    which means that the guest can completely delete the frontend.
    (They can't recreate it because they don't have write permission
    on the containing directory.)
    
    2. A guest has write permission for the backend path recorded in the
    frontend, ie, it can write to
      /local/domain/$DOMID/device/$KIND/$DEVID/backend
    which means that the guest can break the association between
    frontend and backend.
    
    So we can't rely on iterating over the frontends to find all the
    backends, or examining a frontend to discover how a device is
    configured.
    
    So, have libxl__device_generic_add record the frontend and backend
    paths in /libxl/$DOMID/device, and have libxl__device_destroy remove
    them again.
    
    Create the containing directory /libxl/GUEST/device in
    libxl__domain_make.  The already existing xs_rm in devices_destroy_cb
    will take care of removing it.
