2dc1113a94 Bluetooth: CAP: Add support for handling ASE errors
If we get an error/rejection from the CAP acceptor when
performing the Unicast Audio Start or Stop procedure then
we need to abort the procedure and let the application determine
what the next step is.

This change triggered a corner case when connecting to multiple
CAP acceptors as the CAP initiatior. This was also fixed as part
of this.

756f5f940c Bluetooth: BAP: Disallow bt_bap_stream_stop when CIS is not connected
When the CIS for a BAP stream is not connected, we cannot truly
be in the disabling state (the only state the stop operation
can be performed by the unicast client).

The reason for this is that if the CIS is disconnected, then
the ASCS server shall transition to the QoS Configured state
regardless of whether it has received a receiver stop ready
command from the unicast client.

5965ffea86 Bluetooth: BAP: Dont discover ASE CP if ASE not found
Added a check in unicast_client_ase_discover_cb that if
no ASE was discovered, then it would stop the discovery
there instead of attempting to call
unicast_client_ase_cp_discover to discover the control point
which would not be useful to use anyhow.

This terminates the discovery earlier in case of the remote
side not supporting the audio direction we are discovering.

8acb1cc577 bluetooth: host: conn: Check if *conn is not NULL
This commit adds a warning and a Kconfig option to `bt_conn_le_create`
and `bt_conn_le_create_synced` functions which are meant to warn a user
of a potential leakage of an active connection object.

This change is implemented due to frequent incorrect use of the
connection pointer where a pointer to an existing connection object
is overwritten by `bt_conn_le_create` and `bt_conn_le_create_synced`
functions which in turns leads to sporadic critical bugs. See
https://github.com/zephyrproject-rtos/zephyr/pull/78284#discussion_r1754304535
for more details.

The Kconfig option is introduced instead of always returning the error
to not affect current implementations. However, it is recommended to
keep this option enabled to avoid potential bugs.

At same time, if another thread(BT RX) all schedule\_send will cause

ADV\_FLAG\_PROXY not set currentlly.

Add ADV\_FLAG\_SCHEDULE\_PENDING indicate mesh buf has been pendings

as we can't break or terminated adv\_start, so we must waiting proxy
advertising enabled.

But after https://github.com/zephyrproject-rtos/zephyr/pull/68558

c5a126cedb bluetooth: host: LE CS subevent result reassembly
Adds HCI support for LE CS subevent result continue
event and the reassembly logic for the partial results.

When subevent results are completed or the subevent is
aborted, the user callback is invoked with a buffer
pointing to the HCI event buffer, so no copy is done.

When subevent results are incomplete, then a reassembly
buffer is allocated from a fixed sized pool. This buffer
is used for the reassembling of the subevent result
containing all of the step data, which is then passed
to the user via the callback. kconfigs have been added
to set the size and the count of the reassembly buffer.

5f59b35b42 Bluetooth: Host: Fix issue where uninitialized value was used
This change makes sure that when a call to `bt_id_set_scan_own_addr` is
sucessful, i.e., the return value is 0, the `own_addr_type` will
be set by the `bt_id_set_scan_own_addr`.

Not setting the `own_addr_type` in a successful call to
`bt_id_set_scan_own_addr` causes, for example,
the `start_le_scan_ext` method in `scan.c` to use an
uninitialized `own_addr_type`.

Eventually this results in an unexpected failure further down in
`start_le_scan_ext`, when sending HCI command to controller with
an uninitialized `own_addr_type`.

74972e694b bluetooth: host: l2cap: Check conn state before queueing PDU
In case of UATT, if a connection was lost while user was holding a read
or write attribute callback, `bt_l2cap_send_pdu` (called from
`att.c::chan_send`) will anyway queue a PDU and trigger tx work. The PDU
won't be sent eventually, but neither will hold an error code, which
will allow it to bypass the error check in `att_on_sent_cb` and call
`att_sent` function.

For EATT `bt_l2cap_chan_send` is used which already handles this case
and the error code is passed to `att_on_sent_cb`.

This change adds connection state check to `bt_l2cap_send_pdu`
preventing from unnecessary code execution when connection does not
exist anymore.
