according to MediaRecorder::setMaxDuration documentation we should disable duration limit
when zero or negative time is passed. Currently setParamMaxFileDurationUs was treating
zero/negative as an error case. Fixed that.

o Make the API consistent with SF framework, which the MediaSource
provides a return status for stop
o Also, helps to convey errors that occurred right when a
premature stop() is called, leading to a potentially
mal-formed output file.

and reduce rounding errors in calculating the sample duration
- Default time scale for tracks other than audio is set to 90000.
- Audio track by default uses the audio sampling rate as the time scale.
- Default movie time scale remains to be 1000.
- The default time scale values will be overwritten by a user-supplied value if exits.

- default interleave duration is set to 1 second
This can dramatically reduce the memory usage
by the MP4 file writer.

Added methods to AudioTrack and MediaPlayer java classes to enable use of
auxiliary audio effects. The effect can be attached and detached by specifying its
ID and the send level controlled.

- Since the software encoder assumes the input is YUV420 planar,
color conversion needs to be added when the input color format
does not meet the requirement. With this patch, I only added
a single color conversion from YUV420 semi planar to YUV420
planar. We can add more as we go.

The visualizer enables application to retrieve part of the currently playing audio for visualization purpose.
It is not an audio recording interface and only returns partial and low quality audio content as a waveform or
a frequency representation (FFT).
Removed temporary hack made in MediaPlayer for animated wall papers based on audio visualization (snoop() method.
This commit also includes a change in AudioEffect class:
- the enable()/disable() methods have been replaced bya more standard setEnabled() method.
- some fixes in javadoc

Also:
- Allowed start() call when encoder already starts and stop() call when encoder has not started yet
- Handled default value for audio/video sources/encoders and file output format

- An alternative would be to define a common base class that
both MediaRecorderClient and MediaPlayerClient can derive.
But since the common code, onTransact() and notify() uses
some Binder code, having a common base class may not gain
us too much in terms of code reuse.

- Track the completion of the authoring
- Add multiple camera support for authoring by accepting a camera id parameter

Audio sessions are used to associate audio effects to particular instances (or groups) of MediaPlayers or AudioTracks.

- Some H264/AVC encoder output start code in each output buffer, and others don't.
This patch always strips the start code first so that the sample contains the correct size.
- Also properly initialize the interleave duration.

1. QCOM camera HAL does not honor the preview frame rate set request. see bug - 2701282
2. QCOM video encoder has lots of 0-length output buffers if the default level setting is changed. see bug - 2660974
