audio_policy: force cancel unexecuted device routing command

-unexecuted device routing command can be handled for a none active
 output and cause wrong audio routing for the other active output
-cancel the pending device routing command if stream is voice call
 and new device is none

alsa_sound: call voice volume api for direct output also

- Voip volume is not applied on direct output and as a result
  volume cannot be adjusted for some voicemail applications
  which opens direct output stream with mode set to IN_CALL.
- Voice volume is applied only for primary output and volume
  command is not sent to HAL for direct output.
- Call voice volume api for direct output as well from policy
  manager.

hal: fix mutex unlock issue

If a audio/voice usecase is active, hal should re-try the speaker
calibration.Speaker portection mutex was not being unlocked for this
usecase which causes ANR.Change unlocks the mutex which fixes the issue.

audio: Starting proxy thread when there is an active stream

- Proxy thread is started from DoRouting only when previous
  and current devices are external devices. When CS call
  is ended while BT Headset is connected, we get a route
  call to ear piece intermittently and then for BT A2DP to
  resume the music playback. As previous device is not
  external device, Proxy thread is not started automatically
  in this scenario. This is blocking pcm_write call for
  touch tones as ear piece is disabled and data is not
  consumed by proxy device as well

- Fix is to start proxy thread after the route call when
  pcm_write for any stream is in progress

audio/msm7630: Add latency support for LPA

-Audio loss for few seconds on headset connection.
-Stream is unmute in checkDeviceMuteStrategies before device switch
occurs.
-Increase delay in tempMute to ensure unmuting happens after device
switch happens. Also change latency for LPA to correct value similar
to that of hpcm.

audio/msm7630 : Stability issue with LPA play back.

- ANR is observed during LPA playback when there is song switch for
  every few seconds
- The song switch does not happen when the song is played till the end
- Native crashes are observed during rapid seek, next and previous
  song switch operations. There is some race condition between write and
  flush which results in adding a buffer multiple times to empty queue.
  This tries to free the buffer multiple times during reset and results
  in native crash. Fix this issue by adding proper mutex in write and
  flush calls which synchronizes these operations and avoids crashes.
  After Pausetimeout, reset is called due to which EOS is posted
  to observer. This results in start or reset operation on a closed
  sink leading to crashes. Avoid posting EOS if reset is already
  called.
