libstagefright: LPAPlayer: Fix choppy playback on BT.

-Music playback on BT A2DP device is choppy/glitchy
-Decoder thread hogs the CPU this starves A2DP thread from data.
-Fix is to use small buffer(64k) only in the case of A2DP playback.

 libstagefright: Fix ANR during voice call recording when call ends

- While doing voice call recording, when the call ends ANR observed
- When the call is disconnected, audio HAL receives -1 from driver and
  audio HAL propagates this error to AudioFlinger.  But AudioFlinger
  is not sending error status to audio source to stop recording.
  Because of this audiorecord thread keeps on waiting for buffers
  which is resulting in ANR.
- To avoid indefinite wait, a timeout of 1 sec is set for buffer
  in audioSource and after timeout, -ETIMEDOUT is returned
  to recorder thread.

  after decoding the first frame.
- Removed the same to fix no audio issue with specific ADIF clips

frameworks/base: Fix for pause/resume issue while LPA playback

- If LPA playback is paused and resumed immediately, the audio
  resumes for sometime and then the playback switches to next
  clip due to error in OMXCodec.
- In the LPA pause implementation, the source, OMXCodec, pause
  is being called which does not handle executing to pause
  state transition. So this causes decoding issue while resuming.
- Removed unnecessary pause/resume API calls to OMXCodec to fix
  the issue.

-Issue: In LPA playback if seek is issued, the pcm driver
starts after a fill buffer and write is completed. If pause is
issued before the driver starts, audio pause fails and results
to a sudden jump in the playback or to an EOS at random

-Testscenario: Flush,immediately followed by Pause in LPA playback.

-Fix: Pause is handled when the pcm write is completed. This is
acheived by a conditional wait on the pcm write done.

libstagefright: Ensure pcm_prepare is called only when routing is

- LPAPlayer does Derouting, pcm_prepare and pcm_close during pause.
- pcm_prepare should not be called after derouting, as the driver
tries to prepare a session which is already derouted.
- This results in no backend errors in kernel for LPA Front end
session as the backend is already closed with derouting.
- Fix the issue by ensuring pcm_prepare is always called only
routing is still active.

media/libmedia: Release the session only for non-lpa clip

Issue 1:
- The session id is not acquired for LPA clips in AudioTrack
  however destructor tries to release it at the end of LPA
  Playback.
- This cause corruption and eventually causes the ref count
  to decrease on every LPA clip. As a result the application
  of effects is not consistent
- This issue is fixed by releasing the session only during
  non-lpa clip

Issue 2:
- There was noise for initial buffers during LPA playback
- Mixer thread was applying effects for LPA effect chain
- Prevent this by ensuring when lpa session is active,
  mixer thread does not apply effects on the LPA chain

Wipe the user data out in any case.

When the external storage is not mounted, the android system won't
wipe out the user data (i.e. "/data") if wipeData() is called with
the flag WIPE_EXTERNAL_STORAGE.

We think that the user data should be wiped out in any options and
also wipeData(int) method currently supports also for a external
storage. So we will also change the API reference comment.

If we should care about backward compatibility of this method behavior
with the option WIPE_EXTERNAL_STORAGE, then we would add an another
bitmask something like a ALWAYS_RESET.
