  avutil/log: Set AVClass* in av_expr_eval()
  
  Otherwise it is possible for av_log() to receive a non-NULL object
  with a NULL AVClass pointer; the default log callback handles it
  gracefully, yet this is probably an API violation.

  avcodec/ffv1: Use dual run coder for fltmap
  
  This improves compression by 0.1% overall and 44% for the changed table
  I tried several other things but so far this is the best
  compromise between complexity and compression
  
  This can also be extended to 32 and 64bit floats

  avcodec: Don't log to private context
  
  While it is save for these codecs (they all have private contexts),
  it is customary to always use the AVCodecContext for logging.

  avcodec/{h263,ituh263,msmpeg4,snow}dec: Use proper logcontext
  
  The logging functions here can be reached by codecs without
  private class, so that the log callback will receive a non-NULL
  object whose AVClass pointer is NULL. Although the default log
  callback handles this gracefully, it is probably an API violation.

  avcodec/mpeg12dec: Use proper logcontext
  
  When used with the "mpegvideo" or "mpeg1video" decoder (which do not
  have a private class) this would lead to the log callback receiving
  a non-NULL object with a NULL AVClass pointer. The default log callback
  handles this gracefully, yet it is probably an API violation.
