dvb.media_addon: Support dumping of the raw mpeg ts data.

- Main purpose is to debug a/v synchronization issues by playing the dumped
  mpeg ts data in alternative video players (like ffplay or MediaPlayer) and
  see how those behave.

- The commit diffs shows some coding style violations (max. line length) that
  show up throughout the whole DVBMediaNode class. Those will be fixed in the
  next commit to keep a clean separation between the different code changes.
