[media-workshop] [RFC] Media graph flow for an hybrid device as discussed at the media workshop

During the discussions at the Media Workshop, we came with some dot files that would describe a hybrid PC-consumer TV stick with radio, analog video, analog TV and digital TV on it.

I consolidated all the dot files we've worked there, and added the connectors for RF, S-Video and Composite.

The dot file and the corresponding picture is at: http://linuxtv.org/downloads/presentations/mc_ws_2015/dvb-pipeline-v2.dot http://linuxtv.org/downloads/presentations/mc_ws_2015/dvb-pipeline-v2.png

As my plan is to start working on some real driver to produce such graph, please validate if the entities, interfaces, data links and interface links are correct, and if the namespace nomenclature is ok, or if I miss something.

Thanks! Mauro
