- Patch #22786 by mathias: now that db_affected_rows() returns the number of rows matched instead of only changed we can get rid of the hacks that worked around this.

- Patch 20910 by chx: centralize print theme page.

- Fix missing format_plural()

- Clean URLs: search/type/keywords e.g. "search/node/drupal release". The search
  form is POST submitted, but drupal_gotos to a GET page. This makes it easy to
  copy/paste search URLs, and makes the pager a lot cleaner.

- Remember the search keywords when switching between the search tabs. This is
  done through the same GET URLs rather than the session, so it does not mess up
  between multiple browser tabs.

- Report which keywords were ignored because they were too short.

- #820: Provide search block

- Treat multiple wildcards in a row as one
