Tell status in top comment. Use debug logging instead of print to be able to
see timing issue in debug log viewer. Add more commandline flags. Test reverse
playback.

*
* Builds a pipeline with two audiotestsources mixed with adder. Assigns
* controller patterns to the audio generators and test various trick modes.
*
* There are currently several issues:
* - adder only work with flushing seeks
* - backwards playback does not work for adder at all
* - there is a gap of almost 4 seconds before backwards playback
* - it is "waiting for free space"
* - using sync=false on the sink does not help (but has some other weird effects)
* - using fakesink shows same behaviour
*
