  Linked list manipulation routines
 
  this is a very standard linked list structure
  used by many many programmers all over the world
 
  The lists have been modified to be doubly linked.  The
    first element in a list is always the header.  The 'next'
        pointer of the header is the first element in the list.
        The 'prev' pointer of the header is the last element in
        the list.
 
  The 'prev' pointer of the first real element in the list
    is NULL as is the 'next' pointer of the last real element
        in the list
