Workaround the access that check if datapath is NULL when
the stream has already been released. Memory Pool overwrites
first 8 bytes to maintain the free list and free count. This
causes the datapath fields if placed in the first 8 bytes to
not be NULL after the memory is freed.

By default, on errors, pd_decode_command replies with osdp_NAK with
sub-error code set to OSDP_PD_NAK_CMD_LEN (achieved using the ret ==
OSDP_PD_ERR_GENERIC check before return). This is works for all packet
framing errors; but when a more specific error code needs to be sent, ret
has to be set to something other than OSDP_PD_ERR_GENERIC (a suitable error
code happens to be OSDP_PD_ERR_REPLY) to prevent the tail check from
overwriting the error info.
In CMD_KEYSET, we fill a more specific error code but do not set the ret to
OSDP_PD_ERR_REPLY. It causes this error to be reported as a framing
error hence loosing some extended info about the error. Fix this issue by
reordering the checks a bit.

During handshake, only certain types of secure block types (<= SCS_14)
are allowed. A rouge CP/PD can try to bypass the handshake by directly
sending a secure block type ahead of the sequence and gain a secure

OSDP specification section 5.7 states that a transmitting device has to
drive the transmission line to a marking state for a period of one char
in the current baud rate. This can be achieved by sending 0xFF. Since
this is not mentioned in the packet structure definition, many commercial
implementations of OSDP out in the wild do not send/expect this byte.
To work with such non-conforming devices, we will try to be as flexible
as possible in the PD: send mark byte only if the other side sent one. In
case of CP, we have no option but to send the mark byte to be as close
to the specification as possible. If a particular use case needs the CP
to not send it, we will provide a Kconfig option to disable it.

OSDP compliant devices communicate their capabilities and discover what
their peer can and cannot do. Right now, PD advertises these capabilities
and expects CP to honor them. Although this is not known to cause any

capability was enabled and advertised.

The net_context/TCP connection context ref counting needed to be fixed,
to avoid situation where TCP connection context could be released
before net_context is released.
Generally, this commit modifies the ref counting of the above as
follows:
* net_context is referenced both by the application and TCP stack, when
created.
* TCP context is referenced by the application when created. The TCP
stack adds ref to the TCP context only after connection has been
established.
* TCP stack needs to call the final upper layer callback when connection
is closed, but before the TCP context is released (i. e. to give upper
layer chance to dereference the context on its side). For this,
tcp_conn_close() was introduced which is called from within TCP stack
instead of directly dereferencing the TCP context.
* TCP stack dereferences the net_context only after the TCP context has
been released (i. e. upper layer has dereferenced TCP context on it's
side and connection has been tear down, if established).

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.
