When a maximum duration or number of advertisements has been set for an
advertisement set, we will exceed that limit if the last advertisements
happen to be overlapping (ie. we have two primary advertisements pointing
to the same AUX_ADV_IND).
We now have a check in the ticker_cb that will ignore the callback if the
state is such that advertisement would have been stopped if ull_adv_done()
had been allowed to run in the meantime.

If the ACL disconnects, then the unicast server cannot send
a notification to the client about the endpoint and
stream being released. We now call the released callback
if the stream's endpoint was not idle before the disconnection.
Similarly the unicast server (ASCS) did also not call the
released callback if the ACL disconnection causes a endpoint
release.

Wait until encrypt change to trigger the re-subscription quirk.
Otherwise it could fail with insufficient security.
Also gate it behind a kconfig to make apparent its dependencies:
If `add_subscriptions()` is executed in the first place, that means that
the device was bonded and thus that it has to encrypt the link eventually.
`BT_GATT_AUTO_SEC_REQ` should take care of that.
Also add a new flag to `bt_gatt_subscribe_params` to not send the same CCC
write multiple times in some cases.

The nRF HW models have been updated to correspond to a 52833 instead
of a 52832. Let's follow them.
The motivation for the change is to enable proper BIS encryption support
(for BT LE Audio ISO).
Changes:
* Point in manifest to latest HW models
* SOC_COMPATIBLE_NRF52832 has been removed, and SOC_COMPATIBLE_NRF52833
added in its place (with no uses at this point)
* Where SOC_COMPATIBLE_NRF52832 was used to set encryption like for a 52832
(to avoid using the MAXPACKETLENGHT), we set the condition to just
SOC_NRF52832.
Note: The MAXPACKETLENGHT register exists in the new simulated nrf52833,
thought it does nothing.
* In the BLE ctrl LLL radio HAL, all macros are renamed accordingly
(timings are NOT changed).
* Board dts definition now refers to the 52833 soc definition. New 52833
features set as not supported by now.

This reverts commit 5824ac90ecd8dd06d9ea117d345dbc6b069e5840.
The resulting revert takes into account changes to the predicate that

In the resulting revert, the predicate guarding the use of `resp_addr`
is differs from the naive revert because the intention of that predicate
is to know when `conn.c:bt_conn_le_create` decided to use the Host

New LLCP will process the CIS establishement in the TX path, meaning it
will only process once every ACL connection interval.
If ACL connection interval is significantly longer than the ISO
interval, CIS packets corresponding to the ACL connection interval will
be lost. This may cause latency in audio rendition.
By processing the CIS establishment in the RX path, notification will be
sent immediately, and audio path is enabled fast to reduce latency.
When a CIS fails to establish, the controller shall complete the
procedure by sending a CIS_ESTABLISHED event containing the error.

To be able to timely start the first CIS/CIG, if the requested instant

To enable ULL/LLL to prevent adding latency when LLCP is waiting for
instant, local- and remote procedures with instant now expose a function
for checking this state.

When we receive Node Reset message, we schedule work in the system
workqueue to call bt_mesh_reset(). In bt_mesh_reset() we call
bt_conn_disconnect() to disconnect proxy client. bt_conn_disconnect()
will put a buffer to a pool and call k_sem_take to let BT HCI TX thread
process this buffer. Because we stop scanner after disconnecting the
proxy, we can still receive a message at this point. Since BT RX thread
has higher priority than the system workqueue, if we receive a message
while in bt_mesh_reset(), it will be processed when we call
bt_conn_disconnect().
Stop scanner before resetting the mesh to avoid processing of a received
mesh message while in the process of resetting mesh.

If, while storing app or net key, or changing cdb, we receive another
mesh message that affects setting of the same key that the mesh
currently stores, the new change won't be stored.
The settings subsystem API has rescheduling point inside. The mesh
settings are stored in the system workqueue and by default mesh messages
are processed from BT RX thread which has higher priority than the
system workqueue.
When the case above happens, a new change will be written to the same
cache entry. But this cache entry will be invalidated after leaving
settings API, which in turns will invalidate the new change:
- Receive Config AppKey Add message
cfg_srv.c -> app_keys.c: bt_mesh_app_key_add()
app_keys.c: update_app_key_settings()
app_keys.c: bt_mesh_settings_store_schedule()
- store_pending() in settings.c is scheduled
settings.c -> app_keys.c: bt_mesh_app_key_pending_store()
app_keys.c: store_app_key() called to store new app key
app_keys.c: settings_save_one() calls flash driver and sleeps
- Receive Config AppKey Delete message while in sleep,
which wakes up BT RX thread before returning to the system workqueue
cfg_srv.c -> app_keys.c: bt_mesh_app_key_del()
app_keys.c: update_app_key_settings()
app_keys.c: app_key_update_find() finds entry and returns it
app_keys.c: update->clear = 1
app_keys.c: bt_mesh_settings_store_schedule()
- returning back to bt_mesh_app_key_pending_store() from
settings_save_one()
app_keys.c: update->valid = 0
- the key won't be deleted next time store_pending() is scheduled.
This change moves entry invalidation before calling settings API so that
after returning from settings API, a new change won't be unintentionally
invalidated.
