bluez5: make room for a2dp duplex channel

Browse source 
Some non-standard A2DP codecs (FastStream/aptX-LL) have "voice duplex
channel" that can be used to provide an A2DP duplex mode.

Add support for duplex channels, accounting for the fact that the two
directions may be encoded with different actual codecs.
