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

audioflinger: EffectModules are updated with device change

Issue: Effects modules are not updated with the device change
information
Fix: 1) Add setDevice information to mLPAEffectChain
2) Remove the return after sending the device route information to
Direct track so that mixer thread is also aware of the device
change for EffectsChain

libstagefright: Query AudioSystem for suggested record mute duration

- AudioSource mutes a pre-defined duration (defined by kAutoRampStartUs)
  at the beginning of a recording.
- 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.

libstagefright: Convert mono to stereo for LPA clips

- Sound effects are not supported for mono clips
- Repetative calling of effects_configure and effect_process for
  mono clips is resulting in crash in the sound effects library.
- So, Mono clips are now converted to stereo by copying the left
  sample to right.
- This is same as what Resampler does in Non-LPA Playback.

audioflinger: Fix to set volume from MediaPlayer in Tunnel mode

Issue: MediaPlayer.setVolume does not have effect on Playback
volume in TunnelPlayer mode
Fix: the left and right volume parameters of setVolume are
hardcoded and defaulted in DirectAudioTrack. Updating the
parameters from the input arguments fixes the issue

audioflinger: Fix a deadlock

- A deadlock will happen if the obit recipient
  registered by the DirectAudioTrack is called.
- Fix this by moving the lock acquisition in DirectAudioTrack::clearPowerManager()
  to after DirectAudioTrack::releaseWakeLock() is called.
- Also synchronize use of mPowerManager in the DirectAudioTrack
  destructor with DirectAudioTrack::clearPowerManager()

libstagefright: TunnelPlayer: update condition to send SEEK_COMPLETE

- If the client tries to seek to 0 (e.g as a result of LOOPING)
  without ever calling getPosition(), we will always sent an immediate
  seek notification without seeking.

libstagefright: Remove unnecessary code from TunnelPlayer

- TunnelPlayer tries to mimick AudioPlayer when trying
  to delete the extractor source.
- It is needed for AudioPlayer as the OMXCodec object
  is referenced by the CallbackDispatcher as well as AudioPlayer.
- This condition is not true for TunnelPlayer, so why do it.
