frameworks/av: Fix the LPA-AudioEffects dead lock issue

- Issue:Deadlock occurs when the LPA clips are subjected to
  rapid next from BT device and simultaneously on/off the
  audio effects.
- Rootcause:some times flinger thread processing
  LPAPlayer/directtrack next deadlocks with the thread
  working on effect configuration as both of them
  contend for the audioflinger::mlock and effectmodule::mlock.
- Fix1:AudioFlinger::deleteEffectSession() not to acquire
  audioflinger:mLock  instead take the mLPAEffectChain.mlock.
- Fix2:ThreadBase::effectConfigChanged() not to acquire
  audioflinger::mlock.

frameworks/av: Enable subsystem restart for LPA/Tunnel

-Audio Daemon in Audio HAL intimates AudioFlinger
 of ADSP status (online/offline) using set_paramaters.
-AudioFlinger send set_parameters to its clients
 which is DirectTrack used for LPA/Tunnel playback.
-In case of ADSP crash during LPA/Tunnel playback,
 clean up of DirectTrack is initiated.

libstagefright: Create MP3 decoder libraries without OMX layer

- With the current MP3 OMX SW decoders, the decoding time
is increased w.r.t the libraries without OMX layer that are
present in GB. This increase in decoding time results reduction in
power savings in LPA mode.
- This commit is to remove OMX layer for MP3 to reduce the
power consumption in LPA mode

Change-Id: Ie194b11619de9ba43cd85dddbf7892239858945d

frameworks/av: Add metadata mode changes to LPAPlayer

-Seek to EOS was causing playback to hang for 3 seconds before
 switching to the next clip.
-This is because the lpa driver works on period size. Partial
 buffers are not handled.
 Add support for metadata mode changes to LPAPlayer to support
 partial frames.

audioflinger:Set correct device while creating effects

Change-Id: Id2c96c1f1fe4cdfc2795c86caa050f31f15e7f8d
  -Issue: Effectmodule is created with stale output device
  -Rootcause: While creating effects the output device set is
   output device of mixer thread, which is stale and
   not updated, so effects use the wrong/old device as
   the output device and leads to issue such as difference
   in volume level after setting correct device etc.
  -Fix: Cache the latest device value for direct track
   in a flinger member variable when setparameter of
   flinger is called with new device and
   audioflinger::openoutput is called.
   Use this cached value while creating effects
CRs-Fixed: 496866

libstagefright: Fix ANR with rigorous rewind of 3gp LPA clips.

-ANR is seen with rigorous rewind of 3gp LPA clips.
-The lpa destructor waits for decoder thread to be killed when
 the thread function has not got the time-slice to execute after
 creation.
-Use mLock instead of extractor mutex. use mLock before signalling
 the thread to avoid indefinite wait.

Frameworks/av: Fix to prevent deadlock in AudioEffects

-Write is blocked waiting for effect chain lock and this causes
decoder thread to wait indefintely.
-Sometimes it is observed that effectschain is locked before
mLPAEffectChain is initialized and but unlocking is skipped if
mLPAEffectChain is initialized in between.Due to this LPA
silence and framework reboot issues are observed as
applyEffectsOn() cannot acquire lock to progress further.
-Use flag to check if all effects have been locked and unlock
accordingly to prevent the deadlock scenario.

framewroks/av:Fix ANR at the end of video recording

- While doing video recording, when the recording
  ends ANR observed while doing stress test for
  many hours
- When the recording is stopped, audio HAL receives error
  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.

libstagefright: Fix for OMXCodec::read() getting blocked

- Sometimes notification sound is not heard if it is played
  and stopped multiple times in a short duration.
- If OMXCodec::read() gets blocked for filled buffers while
  in pause, it never returns as mFilledBuffers is always empty.
  Due to this AudioTrack destructor never exits as it waits for
  the AudioCallback thread to unblock it.
- Ensure OMXCodec::read() returns even if timeout occurs while
  in pause and handle the same in AudioPlayer by returning zero
  bytes in AudioCallback.

- AudioSource mutes a pre-defined duration (defined by kAutoRampStartUs)

- Instead, query the audio system for any ongoing playback streams
  and use its output latency to calculate the duration to mute the incoming PCM stream.
- This assumes all current playback threads will be paused once recording
  is started.

frameworks/av: Fix for failure in CTS MediaRecorderTest cases

 -Issue: MediaRecorder CTS test cases are failing.

 -Root Cause: Running the CTS test "testRecorderRandomAction" at beginning
  sets the huge file size and stargeFrightRecorder set the 64 bit file
  offset.
  In MPEG4 writer estimateMoovBoxSize depends on a static const
  variable which uses this file offset info.
  As the variable to calculate estimateMoovBoxSize is static const it
  remains same for next media recording session even if file size is small.

 -Fix: Don't use static const variable which is used to calculate
  estimateMoovBoxSize as its value may change depending on file offsets.
