A few related changes:

Browse source 
* Change the encode_sample routine to simply return normal memchunks allocated from the mempool.
* unref the memchunks returned from encode_sample when we are done with them.
* Create an encoded 'silence' sample and play this at all times to prevent hangup and to 'hog' the airtunes device

This now works and can be used as a regular sink albeit with a constant latency of about 8 seconds :s
