#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 follow up patchby myself: document the node_load internal cache and external cache, and how they interoperate

- Patch #168028 by dvessler, merlinofchaos, pwolanin et al: both theme functions and templates may need include files. Flush your caches.

#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)

- Patch #163191 by hswong3i: removed db_num_rows() for compatibility with Oracle and DB2.  Also a performance improvement. (Correct version this time.)

- Patch #163191 by hswong3i: removed db_num_rows() for compatibility with Oracle and DB2.  Also a performance improvement.

#165766 by hswong3i: node SQL fixes - primary keys have indexes themselfs, unique columns should not allow NULL

 - centralize/reuse some node form saving code
 - fix uploads without JS
 - fix reappearing teasers on node save

    * 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.

#157942 by drumm: only acquire node grants if node loaded successfuly, otherwise there are nasty permission problems

- Patch #147061 by yched, dvessel, pwoladin: properly delete node types.  (These guys are becoming a dream team.  Good job.)

#100641 by kkaefer, ChrisKennedy and RobRoy: change 'Submit' buttons to 'Save' to compliy with the desktop metaphor and actually tell what the button does ('we know it submits the form, but what it does?')

#100636 by kkaefer, webchick and Arancaytar: more specific page titles for node creation and editing

#156910 by asimmonds: fix code indentation problems introduced with new code in this development cycle; only whitespace changes

- Patch #126229 by ChrisKennedy, asimmonds et al: increase node title maxlength to 255 so people can use it to enter publictions with really long titles. ;)

- Patch #20295 by pyromanfo, webchick, Gurpartap Singh et al: allow forum topics to be custom node types.

#146386 by kbahey: refactor 'submitted by user - date' themeing and make it more verbose to translate

#108456 by RobRoy: optional custom teaser lengths and much needed documentation on how node_teaser works

  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.

#154064 by pwolanin: get hook_help() up to speed to menu changes, allowing router path based lookups, and also full path argument lookup with a passed argument array

  This is a very important patch, but one that is merely an enabler.
  Hopefully we'll see more people submitting "action patches" in the
  near future.

  Thanks for the hard work and persistence, John.  *If* you decide
  to update the Drupal Pro Development book to Drupal 6, make sure
  to add a chapter on actions. ;)

#153998 by pwolanin: separate edit a delete permissions, so people who can edit a node cannot delete it too automatically

#154224 by hunmonk: add destination argument to _drupal_delete(), instead of using drupal_goto() directly, so the callback cycle can complete
