libstagefright: Fix to free buffers in error scenarios

MediaBuffer objects are not freed if component transition from
IDLE->EXECUTING or EXECUTING->LOADED fails (or if the
OMX_CmdComplete messages are dropped due to an earlier error)
Additionally with native buffers, the corresponding
ANativeWindowBuffers are not cancelled back in the above scenarios.

libstagefright: Add 2 APIs (suspend and resume) in Mediaplayer

- API:suspend() will just pause the player and release all the decoders
  instead of release the whole player
- API:resume() will just init the decoders again
- Add a check in onVideoEvent()
  to make sure the first seek operation will seek the next i-frame

libstagefright - Fix timestamp overflow

 - change time related variables to 64 bit to avoid overflow
 - composition time calculations were having overflow in
   SampleIterator and it propagates to the rest of the time
   related information for the frames

libstagefright: Add fix for mpeg4 data partition clips

- QC firmware does not support mpeg4 clips with data partition,
  but Google software decoders support these clips.
- Add logic in OMXCodec to parse the VOL header passed from
  QC parser to OMXCodec through kKeyRawCodecSpecificData
  for data partition bit and fallback to software codec if it
  is found.

libstagefright: Checks before freeing buffers on a port

- OMXCodec calls dequeueBuffer on the NativeWindow in a loop
  and registers output buffers with the OMX component.
- If a dequeueBuffer fails, the buffers already registered
  with the OMX component were not getting freed laeding
  to a memory leak.
- On an error, check state of OMXCodec before freeing buffers on a port.
