DashCodec: keep cache of formats to support b2b format change

     - when format change takes place too fast, it will pick up wrong
       format.
     - keep a cache of formats and only issue one sendFormatChange per
       crop change.
     - clear format cache when flushing

Fix for the flicker while changing the resolution in DashPlayer

- Just notify the message of MEDIA_SET_VIDEO_SIZE to JAVA Layer,
  while beginning to play the streaming.
- After the streaming begin to play, don't notify this message,
  while changing the resolution or seek operation finished.
- If we don't set video size,
  windowsmanager will adapt the dimension of the clip by itself.
