[PATCH BlueZ v2 2/4] shared/bap: run callback after setting the broadcast metadata

Without this callback, dbus property setting will stall.

[PATCH BlueZ v2 3/4] audio/bap: fill BIG and BIS for receiver

[Michal Dzik]

This is for some reason a missing feature.
We receive QoS structure from the kernel via BT_ISO_QOS, but BIG and BIS
are not set there. In fact it is even impossible to pass them that way,
as it is only one structure per remote device. That's why we have to parse
BASE data to extract BIS and set it to stream->qos. BIG is not present
explicitly in BASE, but we can use subgroup index with success.

As a result of this commit, MediaTransport1 object has now a valid BIG
and BIS set in QoS property.

[PATCH BlueZ v2 4/4] audio: update QoS dbus property after it is set

[Michal Dzik]

Dbus set and get on QoS property use different data:
- get uses bap->qos
- set uses bap->stream->qos
This works, because bap->qos is a copy of bap->stream->qos. The only
issue is when we set this property and then try to get it. We see old, not
updated copy. Simply calling bap_update_bcast_qos() fixes the problem.
