libstagefright: Handle INFO_FORMAT_CHANGED for dolby clips

  -For dolby clips when device is switched from headset to
   BT multiple times, media error is observed, and playback
   stops
  -When end device is changed, s/w Dolby decoder generates
   format change event which in certain condition leads to
   media error and playback stops
  -Make sure format change error is handled in AudioPlayer
   layer

libstagefright: extend the interface to switch rtp transport

- rtp transport can be changed by setting property "rtsp.
  transport.TCP" and udp is the first choice as
  default. But the property is the global variable and
  affects each instance's behaviour.
  Extend the interface of MyHandler to let each client make
  its own choice. If the client wants to choose tcp first,
  add the string/value "rtp.transport.TCP"/"true" in the headers
  when calling MediaPlayer.setDataSource.

media: Cleanup some unnecessary old code

Remove potential cause of underrun.

1. This part of ProcessAudioBuffer function can make underrun issue.
   Because AudioTrackThread::threadLoop's default case is 'pauseInternal'.

2. Without removed part : If AudioTrack obtain small buffer, then it can request small decoded data to player service without waiting.

3. We already have 'waiting codes' in 'AudioTrackshared.cpp ClientProxy::obtainBuffer', it using '__futex_syscall'.
   If we got 'full shared buffer', then 'ClientProxy::obtainBuffer' waits 'ServerProxy::releaseBuffer'.
   It means, there are duplicated 'waiting codes' for ProcessAudioBuffer.

So I removed this part for preventing underrun issue.

libstagefright: HSR: Read framerate from HSR key

- HSR and HFR keys are made mutually exclusive now.
- In case of HSR, HSR key will be set with requested frame rate and
  HFR key is not set.
- In case of HFR, HFR key will be set with requested frame rate and
  HSR key is not set.
- Check
     if video-hfr key is set
        set kKeyHFR with HFR key value passed by camera
     else check video-hsr key, if set
        set kKeyHSR with HSR key value passed by camera

camera: Always enable preview metadata

 * Remove the ifdefs which enable/disable the preview metadata during
   start/stop preview.  This causes issues with face detection and
   other uses on new hardware.
 * I am not aware of any hardware which still needs this.
