bluez5: support packet loss concealment in codecs

Browse source 
LC3 and Opus have built-in support for packet loss concealment.

Add codec interface for that, and implement for LC3.

Extend media_codec interface so that packets not aligned with socket
reads can be handled, as in HFP. This is required for correct sequence
number counting, and for being able to run codec PLC *before* decoding
the next correctly received packet.
