libstagefright: Add support for custom LPA buffer size

 * On msm8930, during playback over A2DP with DSP Manager effects enabled,
   there's a lot of stuttering with the default buffer size. Stock kernel
   used a buffer size of 32, but that caused no audio at all in CM because
   of mismatch in buffer size between kernel and user space. So up until
   now I've been using a buffer size of 256 to get audio working at all,
   but unfortunately it causes stuttering as mentioned. Hence add support
   for a custom buffer size so we can revert to stock value used in kernel,
   and enjoy no stuttering.

audio: Add track to trackToRemove list when it is terminated

- PlaybackThread loop is continuing for direct output even after
  the track is terminated by the client. This is causing 2 direct
  tracks being active when client starts another session
- Fix is add the terminated track to tracksToRemove list so that
  this track is destroyed properly

audio: Fixed framecount in AudioRecord

- Incorrect frameCount is passed to AudioRecordClientProxy,
  which is used while user side pointer is incremented
  This is causing distortion in SIP call
- Fix is to use frameCount of the shared block instead of
  frameCount passed by the client
- InputBytes initialization is also done in AudioFlinger

audio: update setParameter command time properly

-setParameter is getting delayed regardless of delay is
 present or not. Because setparameter command time is always
 getting updated with wrong values(previous values) with any
 commands.
-Fix is to restrict the updation of command->mTime always.
 Added check to update command->mTime, only when identical
 commands are present.

audio: Initialize LPA variables in audioflinger

 - During initialization of audioflinger, a number of
variables related to LPA are not set to default values.
This causes an undesired side effect that the first
effect in the effect chain is considered to be LPA
enabled. Since LPA does not execute effect processing,
switching xLoud on/off does nothing
 - Fixed by initializing member variables in audioflinger.

scale the kMaxCttsOffsetTimeUs for HFR recording

-timestampUs & decodingTimeUs are scaled for HFR recording
-the difference between these is compared against non-scaled
constant(kMaxCttsOffsetTimeUs).
-fix provided to scale this constant(kMaxCttsOffsetTimeUs)
-and compare against the scaled time difference.

AudioFlinger.cpp - audioConfigChanged_l set for srs Tunnel Device Switch

 - During device switch we were only setting the route
   but was not calling audioConfigChanged_l
 - Hence the effects for the new device would apply only
   when there is a config change.
 - Now we call audioConfigChanged_l during device switch
   setPrameter so that the new effects will be apply as
   soon as device is switched.

Revert "frameworks/av: AAC CSD support for MediaCodec path"

This reverts commit Ic8197138f5107f2a6026c28847e74987d91acc16
Currently AAC CSD is retrieved in MediaCodec using
kKeyAacCodecSpecificData. This support was added as part of
commit Id046b0d4bf96f029c1b6b5d78d753073e38ac841.

stagefright: Conditionally build legacy audio stuff

 * The LPA and Tunnel mode code is entirely deprecated and breaks things
   for devices which don't use the legacy ALSA audio HAL.
 * Exclude this stuff unless explicitly requested.
 * Also enable rendering statistics for all.
