 *
 * Revisions   :
 *    $Log: list.h,v $
 *    Revision 1.4  2001/06/29 13:30:37  oes
 *    - Introduced enlist_unique_header()
 *    - Removed logentry from cancelled commit
 *
 *    Revision 1.3  2001/06/03 11:03:48  oes
 *    introduced functions for new list type "map": map(), lookup(),
 *    free_map(), and extended enlist_unique
 *
 *    Revision 1.2  2001/06/01 18:49:17  jongfoster
 *    Replaced "list_share" with "list" - the tiny memory gain was not
 *    worth the extra complexity.
 *
 *    Revision 1.1  2001/05/31 21:11:53  jongfoster
 *    - Moved linked list support to new "list.c" file.
 *      Structure definitions are still in project.h,
 *      function prototypes are now in "list.h".
 *    - Added support for "struct list_share", which is identical
 *      to "struct list" except it saves memory by not duplicating
 *      the strings.  Obviously, this only works if there is some
 *      other way of managing the memory used by the strings.
 *      (These list_share lists are used for lists which last
 *      for only 1 request, and where all the list entries are
 *      just coming directly from entries in the actionsfile.)
 *      Note that you still need to destroy list_share lists
 *      properly to free the nodes - it's only the strings
 *      which are shared.
