[cvs-nhc98] patch applied (hat): Extended fileformat:

[Malcolm Wallace]

  * Extended fileformat:
  
  New node ListCons has to fields: the element pointer and the tail pointer.
  
  Extended Hidden node with an extra child pointer, that shall point to a ListCons or is NULL.
  
  Modified basic libraries and tools, so that they deal with changes. New nodes currently ignored by all tools, except hat-check (but no particular new check).
  
  For the moment a bogus ListCons is written with every Hidden node, to test if tools can deal with the node. Has to be removed later again.
  
  Otherwise ListCons and additional Hidden node field are not written yet while tracing.
