      The libtar_list_new() function creates a new list.  The flags argument
      must be one of the following values:

           The cmpfunc argument points to a user-supplied function which
           determines the ordering of the list.

           Use the list as a stack.  New elements are added to the front of
           the list.

           Use the list as a queue.  New elements are added to the end of
           the list.

      The libtar_list_free() function deallocates all memory associated with
      the list l.  If freefunc is not NULL, it is called to free memory
      associated with each node in the list.

      The libtar_list_add() function adds the element pointed to by data to
      the list l.  The position of the new element will be determined by the
      flags passed to libtar_list_new() when the list was created.

      The libtar_list_add_str() function tokenizes the string str using the
      delimiter characters in the string delim.  The resulting tokens are
      added to list l using libtar_list_add().

      The libtar_list_search() function searches for an element which
      matches data using the matching function matchfunc.  If matchfunc is
      NULL, a default matching function designed for ASCII strings is used.
      Searching begins from the node pointed to by n.

      The libtar_list_del() function removes the entry pointed to by n from
      the list pointed to by l.

      The libtar_list_dup() function creates a copy of the list l using
      dynamically allocated memory.

      The libtar_list_merge() function creates a new list with flags and
      cmpfunc, in the same way as libtar_list_new().  It then adds all
      elements from list1 and list2 using libtar_list_add().

      The libtar_list_new(), libtar_list_dup(), and libtar_list_merge()
      functions return a pointer to the new list structure, or NULL on

      The libtar_list_next(), libtar_list_prev(), and libtar_list_search()
      functions return 1 when valid data is returned, or 0 otherwise.

      The libtar_list_add() and libtar_list_add_str() functions return 0 on
      success, or -1 on error.
