bluez5: allow codecs to produce multiple packets from same data

Browse source 
Codecs may need to fragment a single encoder frame across multiple
packets that are sent consecutively.

Allow codec->encode() to set need_flush=NEED_FLUSH_FRAGMENT, so that
sink should immediately call start_encode + encode with NULL input data,
to produce the next packet.

Previously, other return values than need_flush=1 were unused, so no
need to bump codec ABI for this.
