- Fix bug in decode_entities() with double-escaped entities.

- By default, do not show comment controls.

- Patch #20103 by Neil: Removing another place where we have hard coded HTML instead of the form functions.  The unpublish selection actually didn't seem to work, so I removed it since we have delete. It should be implemented as a link anyway.

- Patch #18828 by me, jbond and TDobes: moves the textarea hook for 'pre' between the title and the textarea. This makes it easier for simply textarea enhancements like quicktags to add a toolbar just above the textarea.

- Modified patch #19694 by chx: makes sure that block.module deals by default only with regions 0 and 1 as it does now but lets you use block_list with any region you define. This opens many possibilites. You may do a multi region module, with your admin UI using the blocks table as storage and the block_list matcher. Or you may do a sections module using the block matcher without cluttering the current blocks list.

- Patch #19768 by danielc: line 593 in version 1.109 of database.pgsql is problematic. The line creates a unique index for sid. But, sid is already a primary key so doesn't need a unique index on it. Let alone, the syntax is wrong due to wrapping the table name in {}'s. This patch removes the line.

- Patch #19895 by Moshe: currently modules can inadvertently load all other modules during the bootstrap. this is easy to do by calling a node_load() or module_invoke_all(). this degrades performance for anonymous users when caching is enabled.  With this patch, the module writer will see an php error like "Call to undefined function: drupal_set_html_head()" if this is attempted. basically, unavailable functions are actually reported as unavailable.

- Patch #19451 by JonBob: improved consistency of module descriptions.  We should write guidelines for this -- maybe in the PHPDoc code of the _help hook.

- Patch #19590 by Moshe: lazy initialization of the theme system.  Improves
  performance of pages that don't need the theme system (such as RSS feeds)
  and makes it easier to set a custom theme.

- Tweak code style.

- Updated the start date of the updates.

  terms are matched, the query would become very slow.

- Patch #18093 by Junyor: clean up handling of image toolkit code in absence of
  any toolkits.
