audio: Fix for race conditions in direct audio track

-Issue: Mediaserver crash is observed in direct track functions.
-Rootcause: Between write and flush functions, write and destructor
effectpool buffers are accessed without any synchronization that
 might lead to operations on null buffers and cause crash.
-Fix: Use mEffectLock to synchronize access of effectpool buffers.

audio: 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.

audio: Fix crash in flinger during monkey runs

The trackrefptr in DirectTrack descriptor can be invalid and
this can result in a crash is stability runs. Add check for
validity of the trackrefptr before accessing it.

  target name.

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.

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.

audioflinger: SRS effects are not working for LPA

    -Issue: If SRS effects are applied on LPA playback,
     in ARM side there is a delay of 4-5 seconds for effects
     application
    -Root cause: In applyEffects SRS effects are applied first and
     then Android effects are applied.
     In case of active android effects, SRS effects are called
     first and then android effects are called, so buffer with
     SRS effects is getting overwritten with buffer with
     android effects.
     If there are no android effects applied then all
     the SRS effects are overwritten with decoded data.
     So until next write call, SRS effects are not applied and hence delay
     of 4-5 seconds.
    -Fix: In applyEffects first apply android effects and then
     apply SRS effects

audio: Supress redundant effect config events in short duration

Distortion sound persists for the whole song when re-enabling effect in
LPA playback mode till switch to next song. And pop noise is quite obvious
when enable/disable effects in LPA.

As the design of LPA, EffectsThreadEntry() loop is used to handle effect
config changes through applying effects with new config on dsp pcm buffers.
However, it can't handle too many config change events in a short time,
and effect with new configuration will be applied on part of dsp buffers.

Filter out redundant effect config events that come too closely to avoid
applying effect on dsp buffer in vain.

audioflinger: Add Null pointer check while enabling effects for LPA

- MediaServer is crashing when disabling effects after mediaplayer
object is released.
- EffectChain pointer is de-referenced without NULL check, hence
leading to a mediaserver crash.
- Adding a NULL pointer check before using EffectChain object.

audio: Use composition instead of multiple inheritance

- AudioTrack is derived from BnDirectTrackClient along
  with RefBase to receive the notifications from
  AudioFlinger in tunnel/LPA mode. This is breaking
  binary compatibility for the clients which use native
  AudioTrack directly instead of Java based AudioTrack
  API
- Fix is to use composition here instead of inheritance

audio: Added lock during closing of direct output

- Lock is missing when direct output is closed in
  closeOutput_nonvirtual. As mDirectAudioTracks is
  being modified in this function, we need a lock
  here to avoid synchronization issues when it is
  accessed from other methods in AudioFlinger
- Fix is protect direct audio track specific block
  with mLock
