Add Kconfig option to dump only a portion of stack from the
current stack pointer to the stack end. This is enough to
let gdb reconstruct the stack trace and can significantly
reduce the dump size. This is crucial if the core dump needs
to be sent over radio.
Additionally, add another option to set the limit for the
dumped stack portion.

After the PR #85000 the calculation of NUM field of
Block 1 option on CoAP Ack packet started to advance
to next packet block.
We should not update the ctx->current field because it is
used for calculating the NUM field in response packet.
It should point to beginning of the payload,
so the response is correct.

After https://github.com/zephyrproject-rtos/zephyr/pull/72090,
`conn_tx_alloc` no longer blocks, and each buffer always has a
corresponding `bt_conn_tx` object. This eliminates the need to configure
the number of `bt_conn_tx` objects via `CONFIG_BT_CONN_TX_MAX`, since
every buffer now carries its own context even when no callback is used.
This commit deprecates `CONFIG_BT_CONN_TX_MAX` as it is no longer
necessary. Instead, `CONFIG_BT_BUF_ACL_TX_COUNT` is used to allocate
`bt_conn_tx` objects for outgoing ACL data. ZLL already uses
`CONFIG_BT_BUF_ACL_TX_COUNT` to configure the number of outgoing ACL
packets. With this change, modifying the packet count will automatically
adjust the number of corresponding contexts, preventing both context
starvatoin and underutilization.
This approach also aligns with ISO, where the number of `bt_conn_tx`
objects for outgoing ISOdata matches `CONFIG_BT_ISO_TX_BUF_COUNT`.

After https://github.com/zephyrproject-rtos/zephyr/pull/72090, each
packet to be sent (wether ACL or ISO data) has a corresponding
`bt_conn_tx` object, regardless of whether a callback is used.
This means that number of packets Host can send to Controller is limited
by the smaller of two values: ACL/ISO packets Controller can receive,
and the number of `bt_conn_tx` objects allocated by Host.
A mismatch between these numbers may lead to inefficient resource usage
on either Host or Controller side. If Host allocates fewer `bt_conn_tx`
objects than the number of buffers available on Controller for a given
data type, some Controller buffers may go unused. Conversely, if Host
allocates more `bt_conn_tx` objects than Controller can consume, the
excess objects remain unused.
This commit adds a check and issues a warning if the number of
`bt_conn_tx` objects is not aligned with the number of ACL/ISO buffers
reported by Controller via the LE Read Buffer Size v1 or v2 command.

Avoid early enabling of the syslog backend in

When CONFIG_NET_IPV4_ACD is enabled, the assigned ip address has
not been checked, when the other dhcpv4 options are parsed, this would
lead to the syslog backend being enabled before the src ip address
is valid, so we get lots of warnings about dropd packets, this fixes

Many cellular modems attempt to negotiate an ACCM value of 0x00000000.
While the PPP driver rejects this by default, it does not propose an
alternative. As a result, some modems default to using 0x00000000 after
LCP negotiation. Because the PPP driver expects all control characters
to be escaped, this causes issues during decoding. This change
negotiates an ACCM value of 0xffffffff to ensure compatibility with such
modems.

According to RFC 2131, DHCP clients should use the same xid as
received in the Offer message when sending DHCP Requests. Therefore,
when generating DHCP Request message, the xid value should not be
incremented.
One vague topic is whether the xid value should be updated when
sending Requests from Renewing or Rebinding states, however RFC makes no
exception for those states, and other implementations (dhclient, lwip)
seem to reuse the same xid in such cases, so comply with this behavior.

Pad option (option code 0) can be present in between other options for
alignment. The option has a fixed 1-byte length (i. e. no length field),
therefore it did not fall under the common processing code for
unrecognized options (which include the length field at the second
byte). Therefore, not processing this option explicitly could disturb
other options processing, as the parser would wrongly interpret the next
option code as the length field. This commit adds Pad option handling to
fix the issue.

Fix Central CIS offset calculation for dissimilar ACL and
ISO intervals in use.
Mayfly execution of `mfy_cig_offset_get()` could be after
"LLL Prepare" or before depending on whether a previous radio
event is being preempted or not, respectively; the
`conn->lll.event_counter` may not be pre-incremented.
This race condition is fixed by the fact that we use a
constant instant delta value now.
Dissimilar ACL and ISO intervals may lead to ACL overlapping
or be too close to ISO event, causing preemption; under this
case ACLs "LLL Prepare" would run after `mfy_cig_offset_get`
causing incorrect calculation of CIS offset without the fix.

Move OpenThread-related code from
zephyr/subsys/net/l2/openthread/openthread.c to
zephyr/modules/openthread/platform/openthread.c.
The primary goal of this refactor is to enable the use
of OpenThread as an independent module, without the necessity
of Zephyr's networking layer.
This change is particularly beneficial for simple applications
that have their own implementation of the IEEE802.15.4 driver
and do not require a networking layer. These applications can
now disable Zephyr's L2 and IEEE802.15.4 shim layers and
directly use the OpenThread module, saving valuable kilobytes
of memory.
In this approach if the CONFIG_NET_L2_OPENTHREAD
Kconfig option is set, Zephyr's L2 and IEEE802.15.4 layers
will be used, and everything will function as before.
The main difference is the Zephyr's L2 layer now uses
the OpenThread module, no longer implementing it.
While most of the functions in include/net/openthread.h
have been deprecated, they are still available for use to
maintain backwards compatibility.
