 THIS BREAKS LIVE-TV.

 First part of the new live-tv 'chain' implementation.
 - The RingBuffer no longer is a ring buffer.  Need to look at the locking
 in the class now, it can likely be made much simpler.  Troublesome to
 rename this now, probably should at some point.
 - Live-tv initialization is different, there is no more 'setup ringbuffer'
 command.  Instead, 'spawn tv' takes care of that, and the client sends a
 live-tv chain id to the backend to start appending to.  Once started, the
 client reads the first program out of the chain, sets up the local
 ringbuffer and starts playing it.
 - It automatically creates a new file / chain entry when the program guide
 data changes.  Playback follows along, reloads the chain, and can
 seamlessly playback across the gap.

 Broken at the moment:
 - bttv/mjpeg/plextor usb capture cards (only in live tv).
 - Channel, input changes.
 - Seeking across file boundaries.  Probably, seeking in general.
 - The OSD during live-tv.
 - Getting the proper position map from the encoder.
 - probably more stuff.
