* implement new output API, fixing some bugs and implementing some feature

  requests--let's see what I can dig out of the bugtracker for NEWS--
  and while crossing the road:
   * implemented new zlib API
   * fixed up ext/tidy (what was "s&" in zend_parse_parameters() supposed to do?)

Thanks to Jani and Felipe for pioneering.
