#160043 by chx: array_filter for book admin settings form, which is required based on http://lists.drupal.org/pipermail/development/2006-September/019917.html

#111127 rollback by chx, slightly extended: roll back node_load cache, it needs more thought and discussion, so postponed until at least Drupal 7

#111127 by chx: cache node_load(), so heavy operations loading data from external sources and only invoked once (note that you should do everything dynamic in the view op, not the load op)

#165675 by pwolanin: only show allowed parent items in menu/book select fields to avoid going deeper then what is allowed

    * Removes the hard-coded 'book' type and perform all node actions
      equally on any node type via hook_nodeapi.
    * Achieves 100% integration with the menu system.  Improves
      performance of book rendering.
    * All the algorithms have been changed to use the tree data structure
      returned by the menu system.
    * Added support for 'multiple books'.
    * Some UI improvements.

  This is a momumental patch that took 69 iterations. Although there is
  room for improvement, this is a big step forward.  Thanks for the
  persistence, pwolanin.

  unanimously agreed to rollback the deletion API.  We all support the
  features this patch added, yet not its actual design and implementation.
  After some talk, we decided that it would be better for Drupal -- in the
  long term -- not to go with a solution that isn't 100%. We also recognize
  that in the short term, this patch would have been useful addition. So
  let's figure out how we can implement this properly in D7.
