[PATCH BlueZ v3 00/10] BAP stream reconfiguration

[Pauli Virtanen <pav@iki.fi>]

Implement ClearConfiguration() and Reconfigure() for BAP unicast
MediaEndpoints.

v3:

- Add bt_bap_stream_lock(), instead of bt_bap_stream_discard()

- Separate commit for "detach on RELEASING"

- Move "bap: do not try QoS before links are updated" first,
  as it makes sense standalone

- Add "bap: don't show error when releasing stream"

- Add "bap: delay QoS & IO creation if CIG is busy or setups configuring"

  This reworks the unicast stream creation/QoS/CIG activation logic, to
  avoid doing operations that are impossible due to CIG state machine
  rules, or lead to ID conflicts.

Unicast tested manually on:

- Sony Linkbuds S: switching between AC 6(ii), 8(ii), 11(ii)
- Earfun Air Pro 3: switching between AC 6(i), 11(i)

with corresponding Pipewire branch
https://gitlab.freedesktop.org/pvir/pipewire/-/commits/bap-codec-switch-select

Some more testing is probably warranted.

Broadcast has not been tested.
