Implemented:
-- Combining segments from multiple SDUs in a single PDU for TX
-- Release of PDU based on remaining capacity below threshold
-- Release of any PDUs in production on receiving a timeout for the
upcoming event
-- Release of PDUs in production if source if destroyed
-- Synchronization flag to exclude multiple contexts in ISO-AL

Implements:
-- SDU fragments can be buffered in the ISO-AL so that the correct size
of the SDU can be computed such that it can be released for inclusion
in the first fragment's header
-- Changed SDU emit interface to allow the same structure to be used to
buffer as well as release fragments
-- New configuration BT_CTLR_ISO_RX_SDU_BUFFERS to specify the number of
SDU buffers for each sink
(Buffering disabled when BT_CTLR_ISO_RX_SDU_BUFFERS=0)

Improvement for IAL/CIS/FRA/PER/BI-01-C & IAL/CIS/FRA/PER/BI-02-C
-- Test appears to fail as the transmitted PDU is packed with less data
than is indicated in the segment headers.
-- Guards were included to verify that sufficient data exists in the PDU
before extracting the segment.

timestamps if time information is missing.

This removes the callbacks from capabilities. The callbacks are used for
unicast server role only, while the capabilities are used for the
broadcast sink role as well. Thus the callbacks can be removed as there
is another bt_audio_unicast_server_cb API that is specific for unicast
server role.

Adds Kconfig option for the Mesh Shell Health server.
The shell implementation of Health Server test commands is
dependent on the user adding and initializing the shell Health
Server instance in their application to make the commands functional.
To prevent any confussion about how these commands work, a Kconfig
option has been added to allow conditional compilation of these
commands. In this way the user must actively enable this feature, making

Fix radio_tmr_start_us to be soft realtime, if the requested
start in microseconds is in the past, setup the next
earliest expiry. This is to prevent radio not being started
and not let the LLL hanging. When setup to receive auxiliary
PDU in LLL scheduling, is_aux_sched is set and if radio does
not start and the window is requested to be pre-empted, then
it is blocked from being preempted due to the is_aux_sched
flag remaining to be set. This stalls the scanning
infinitely until explicit scan disable.

If scan is being disabled, rx could already be enqueued
before coming to ull_scan_aux_rx_flush. Check if node rx is
not the last in the list of received PDUs then add it to the
list, else do not add it to the list to avoid duplicate
report generation, release and probable infinite loop
processing of the list. It is possible that node rx has not
be already added in case of last PDU in the chain, under
this case when scan is being stopped add it to the list
before auxiliary context is flushed.
Add the node rx to aux context list of node rx if not
already added when coming to ull_scan_aux_rx_flush. This is
handling a race condition wherein the last PDU in chain is
received and at the same time scan is being disabled.

Fix scan aux context leak on Periodic Sync Terminate. On
Periodic Sync Terminate the `is_stop` flag is set to prevent

If a device sends an MTU that is bigger than our maximum tx buffer size,
that could cause assertion failures down the line.
This PR limits it to the maximum we support (CONFIG_BT_L2CAP_TX_MTU).
The issue has been observed with a gatt discovery procedure, but is likely
present in other places in att.c.
To reproduce it, we need two zephyr shell devices, with one having a larger
MTU than the other:
- connect
- do data length update to the bigger MTU
- set security to 2, EATT channels get connected
- launch a gatt discovery from the device with the larger MTU
- observe kernel panic on the other device when it attempts to add too much
memory to a net buf.

Remove the support for caching ASEs on release.
This is mainly due to the 2-stage design in Zephyr: We
have the bt_audio_stream and the bt_audio_ep, where the
the latter represents an ASE in most cases.
However, once the endpoint goes into the codec configured
state, then a stream must be bound to it. This would be fine
(although a stream is technically not established at this point),
except that a stream is also, for unicast, specified for a
specific ACL. Once the ACL disconnects, the stream technically
becomes invalid, and if the stream is invalid, so is the endpoint.
Based on that, there's no reason (or even option) to keep the
endpoint in a codec configured state, as it would not
have a valid stream associated with it.
If we want to support an ASE going into the codec
configured state on ASE release (or ACL disconnect),
the relationsship between ASEs and streams needs to
be redefined.

This callback allows use-cases where the SDU is much larger than the l2cap
MPS. The stack will then try to allocate using this callback if specified,
and fall-back on using the buffer's pool (previous behavior).
This way one can define two buffer pools, one with a very large buffer
size, and one with a buffer size >= MPS, and the stack will allocate from
that instead.

According to Bluetooth 5.3 Vol 4, Part E section 7.7.65.21 the
Controller should send an IQ report with Packet_Status set to 0xFF
and Sample_Count to 0x0, to inform Host that it is not able to
store IQ samples for all received Constant Tone Extensions and has
failed to sample at least once.
This commit adds handling of such situation for direction finding
in connectionless mode in lower link layer. It includes:
- lack of node_rx_iq_report to store IQ samples,
- lack of free node_rx to report received advertising data (generates
an advertising data report with indication "incomplete, no more to
come" and cancels reception of chained PDUs,
- cancellation of chained PDUs reception due to other scheduling
reasons.
In all of these situations CTE reception must be enabled and number of
received CTEs is smaller than requested by Host.
If there is not sufficient number of node_rx_iq_report nodes and
report was generated, the CTE will not be samples in a given
periodic advertising synchronization event. The CTE will be
sampled again in next event if there are node_rx_iq_report available.
End user applications may check periodic advertising sync event
counter when use of the reports to be sure about sync event
the received report is connected with.

When the node is part of only one subnet, it starts Network ID
advertisements with infinite timeout. It is not an issue when using
legacy advertising and extended advertising with shared set for local
messages and GATT because any message will stop advertisements. However,
when a separate adv set is used for GATT advertisements,
`struct bt_le_ext_adv_cb.start` callback won't be called, but the
implementation relies on that callback to switch to a next subnet.
Calling `bt_mesh_adv_gatt_update()` stop GATT advertisement so that the
implementation can switch to the next subnet.
