This reverts commit 7f68c5a030dc0915c9d78c2627054cda80c4baef.
Add 2 APIs (suspend/resume) in MediaPlayer

- API:suspend() will just pause the player and release all the decoders
  to replace release() which will release the whole player
- API:resume() will just init the decoders again,
  then start() will be called to start to play the streaming
