added --path <path_id> to give the information on the 'path-id' of removed device
<path-id> allows to identify the port to which given device is plugged
in. In case of hot-removal, udev can pass this information for future
use (eg. write this name as 'cookie' allowing to detect the fact of
reinserting device to the same port).
--path <path-id> parameter has been added to device removal handle
(and char *path has been added to IncrementalRemove() to pass this
value) in order to pass path-id to this handler.
