Incorporating logging into Cast:

1. Adding logging to CastEnvironment.
2. Actually triggering logging within the cast library.
3. Adding thread checks.
4. Removing trace calls outside of the logging class.

Open issues: 
1.Use of rtp_timestamp and frame id is not consistent.
In addition, the AudioBus does not include these values.
2. There is a pending cl to switch frame_id to int. This cl does not include that.
3. There are a few more places to add logging.

As this cl is already big enough, all of the above will come in a follow-up cl.
