* modules/stream_out/transrate: New transrating module, based on GPL

  code from www.metakine.com.
  CAUTION : the code is currently very ugly, with static variables, no
  code convention, etc. I check it in "as is" because it may be useful
  to some people.
  Don't expect a bitrate reduction of more than 30 % with acceptable
  quality.
