Integrate emulator so it can process selected packets instead of
replaying them from the sequence. The behaviour is controlled
through the action attribute in hciseq_attr.
If set to HCISEQ_ACTION_EMULATE, hcireplay will use the emulator
to process the packet automatically instead of replaying it.
HCISEQ_ACTION_REPLAY keeps the previous behaviour and replays the
packet using the dump file.
