audio:Avoid AudioTrackThread if Track creation fails

-mAudioTrackThread is starting before the track creation.
 This thread is used to process the audio buffer, which
 is no longer valid if the track creation itself is
 failing.

-Fix is to check for the result of track creation and
 based on the result need to start the mAudioTrackThread.

audioflinger: Ensure SRS effects are applied on active tracks

- When device is switched from BT to wired headset
  without disconnecting BT, SRS effects are not applied
  on wired headset
- Currently SRS module is checking for connected BT
  device and overriding the updated device from framework,
  with BT if BT device is connected
- call the API which will tell SRS module not to
  override the updated device from framework, irrespective
  BT device is connected or not, also while calling SRS API
  from mixer thread check if the track is active

Fix for getPosition after seek

When starting playback with a seek pending
(calling seek before start) there is a brief period
when the audioplayer returns an incorrect position (zero)

This is caused by that mSeeking is set to false
before the position in the audioplayer actually is updated.

accelerate camera recording start up speed

When do initial buffer submit, if do drainInputBuffers() first, it will always wait all input buffers reached,
and then start fillOutputBuffers().During this time, nothing to do in level codec, all time is cost on waiting,
it is especially severe for Camera recording case, for example, in 30fps case, If 3 input buffers are required,
HW codec will wait at least 99ms to start video encoding, since no outport buffer ready at this
time.

After change call sequence, fillOutputBuffers() is done fast firstly, then do drainInputBuffers(),
when receive one input buffer in HW codec, it can start working immediately, because the working condition is reached,
both input port and out port buffers are ready.

RTSP: Don't post AUTimeout check during pause when EOS is nearing

RTSPSource will not issue pause to MyHandler when streaming is about
to finish even when streaming is paused. Thus, in this case,
the accessunit timeout check will continue to see if any packets are
received or not from the server. As there will not be any more
access units coming from server after EOS, the session gets terminated.
In this scenario if resume is issued, the player crashes.

Set the AuTimeoutcheck flag to false in case if pause is not
issued to MyHandler when nearing EOS. Based on the value of the flag,
the access unit timeout check will be performed.

frameworks/av : Add Null check for Audio Track

Check if AudioTrack is available before de-referencing
it's pointer to avoid crashes during stability runs

Rootcause: During Video playback when the audioTrack
init fails due to mediaplayer errors, the getMediaTimeUs
is already getting called resulting in a crash.

Fix: Added NULL pointer check when de-referencing pointer

audioflinger: remove wake lock implementation from APS

-AudioPolicyService is not able to acquire the wakelock.
 None of the Audio functionality is impacted though it always fails
 to hold the wakelock.

-APS tries to access wake lock directly using hardware_legacy APIs
 and it always fails due to lack of capability.

-Remove the wake lock implementation since it always fails and
 it does not impact any audio functionality.

stagefright: Do not drop encoded frames when writer is paused

Since the source drops input frames when paused, there is no
need to drop encoded frames in the writer as we run the risk
of dropping a key-frame.

httplive: fix issues during httplive streaming seek

- Cache the new seek position during the last seek progress.
- Before starting the fetchers, check whether one new seek
  operation comes. If yes, reset to change the configuration
  based on the last cached seek position.
- This change can avoid ignoring the new seek operation before
  finishing the last seek progress.
