Subject: stagefright: Squashed commit of pause/resume features

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 restart streaming playback
- Add a check in AwesomePlayer::onVideoEvent()
  to make sure the first seek operation will always seek to the next
  i-frame

audio: Add pause support for hardware omx component

- ADSP doesn't enter sleep state after wma playback is paused
  and power suspended.
- No support for NT session pause in case of hardware component.
  NT session need to be paused to put ADSP into power collapse.
- Add support of pause in stagefright to ensure device enters
  suspend mode. Also add intermediate states to avoid concurrency
  issues between read and pause.

libstagefright: Drain input buffer on resume

- Buffers returned from codec in paused state are not drained. When
codec is resumed these buffers are not drained until the next flush,
and may cause timed out issue.
- Added change to drain input buffers for sw decoders when resuming.
