audioflinger: Add missing code for FM volume

 * If we used a proper MR2 audio HAL, this wouldn't be needed,
   but building FM support with the hacked up MR1 audio HAL we
   uses fails miserably. Adding this back fixes that.

frameworks/av: 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 policy: Avoid unintended update of a command's timestamp

- When two setParameter calls with different keyValuePairs reach
  AudioPolicyService from HAL, the timestamp of the command received
  later is updated to that of the command received first.
  This is unintended and might cause a delay or advance the processing
  of commands.
- AudioPolicyService processes setParameters calls in the order
  in which it receives them and when two setParameter calls with
  different keyValuePairs come in (in this case, FM volume with a
  delay and routing), the timestamp of the command received last
  (routing) is updated to be processed at the timestamp of the command
  received earlier (FM volume). FM volume is set with a delay which
  causes the delay in routing as well.
- The timestamp of the command should be updated only if the
  keyValuePairs in the setParameters call match.

  commands.

CameraService: Adds support for longshot mode

- This change introduces additional functionality inside
  CameraClient for supporting continuous compressed data
  callbacks. This is needed for 'Burst/Long shot' mode
  where we could have indefinite number of callbacks after
  capture is triggered.

Camera: Dont process dataCalllback if recording is stopped

Issue: Here stopRecording is not finished as the previous
recording frame process has not completed. dataCallbackTimeStamp()
in CameraSource.cpp has stuck in the thread itself waiting for a lock.
In between, reset() function in CameraSource.cpp has called
and acquired lock. Reset() function calls stopRecording.
So the dataCallbackTimeStamp() is continuously waiting.
Unless dataCallbackTimeStamp returns, processRecordFrame
in HAL will not finish.
