Ideally NetStreamGst would be dropped and NetStreamFfmpeg would become
NetStream. MediaParser is already virtual and obtained by the MediaHandler
factory. When the registered MediaHandler is the gst one, it will give
gst-specific MediaParser,VideoDecoder and AudioDecoder subclasses.
Implementations are already present, dunno their state though.

But step 1 (understand/evaluate/improve) is very important here so please
take a look at MediaHandler/MediaParser/VideoDecoder/AudioDecoder first
(being the new stuff) and then sound_handler (being the old thing not yet

For instance, the GST version of sound_handler doesn't support "aux"
streamer concept yet, and we should decide if that's the way to go
(thus implemeting in SoundHandlerGst) or that's to be changed (thus
finding an alternative interface for final sound mixing).
