/**
 * Get a canonical service name for this file system.  The token cache is
 * the only user of the canonical service name, and uses it to lookup this
 * filesystem's service tokens.
 * If file system provides a token of its own then it must have a canonical
 * name, otherwise canonical name can be null.
 * 
 * Default Impl: If the file system has child file systems 
 * (such as an embedded file system) then it is assumed that the fs has no
 * tokens of its own and hence returns a null name; otherwise a service
 * name is built using Uri and port.
 * 
 * @return a service string that uniquely identifies this file system, null
 *         if the filesystem does not implement tokens
 * @see SecurityUtil#buildDTServiceName(URI, int)
