e5890fc779 Bluetooth: Audio: Broadcast source reconfigure missing streaming QoS
When executing the bt_audio_broadcast_source_reconfig the streams
did not get assigned the new QoS, the ISO parameters were not
properly updated and the codec was not set.

which updates the metadata of a broadcast source while
it is streaming.

This is also makes all checks for the "head stream" the same.

e458f5aae6 Bluetooth: Use Zephyr standard log system instead of bluetooth/common/log
The `bluetooth/common/log.h` and `bluetooth/common/log.c` files have been
removed. Files that were using them have been updated to use
`zephyr/logging/log.h` instead.

Those replacement have been done consequently:
- `/BT_DBG/LOG_DBG/`
- `/BT_ERR/LOG_ERR/`
- `/BT_WARN/LOG_WRN/`
- `/BT_INFO/LOG_INF/`
- `/BT_HEXDUMP_DBG/LOG_HEXDUMP_DBG/`
- `/BT_DBG_OBJ_ID/LOG_DBG_OBJ_ID/`

Also, some files were relying on the `common/log.h` include to include
`zephyr/bluetooth/hci.h`, in those cases the include of `hci.h` has
been added.

For files that were including `common/log.h` but not using any logs,
the include has been removed and not replaced.

7ab1cafbc2 Bluetooth: Audio: Add Broadcast source application AD
This refactors how the BAP broadcast source handles the
extended and periodic advertising.

First it removes the start and stop of the extended
advertising, and instead expects the application
(or upper layers) to do this.

Second it exposes API functions to get the
necessary advertising data from BAP (service data and
the BASE), which the upper layers will then also
be responsible for setting and updating.

79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

9b15426455 Bluetooth: Audio: Refactor ISO allocation endpoints
Modify how the ISO channels are allocated for the audio streams,
as well as how the CIG is allocated for the unicast group.

This fixes an issue where the unicast group could not be
fully allocated before _after_ the bt_audio_streams had been
configured by bt_audio_stream_config, thus making it impossible
to create a unicast group before the connections have been established.

This leaves us with 3 basic data types:
1) Streams allocated by the application
2) Endpoints that represent ASEs
3) Audio_iso which is used to couple streams and ISO channels.

The Unicast Group for the unicast client will now have the same
lifetime as the ISO CIG for the central.

6786bbdb32 Bluetooth: ISO: Add sn and ts to bt_iso_chan_send
Add two new parameters to bt_iso_chan_send:
sn: The packet sequence number which shall be incremeted
per SDU interval.
ts: An optional timestamp value used to synchronize SDUs.

The sequence number in the API uses a 32-bit value even though
the sequence number for the HCI command is 16-bit. This is to
properly handle wrapping of sequence numbers, which is much
easier to do with additional bits allocated.

Moves the bt_iso_chan and bt_iso_chan_qos structs
out from the bt_audio_ep struct, and instead use a

This is due to the fact that an endpoint can ever

The support for using a single bididrectional CIS
for two audio streams/endpoints is not implemented
