SenML is technically a JSON based format which can
be encoded as a CBOR. SenML-CBOR specification in
RFC 8428 section 6 states that numbers can be decoded
as an integer.
Also RFC 7049 section 4.2 states that JSON numbers
without fractional part can be decoded as an integer.
I have seen with one commercial LwM2M platform that
the decoder they use, sends floating point values as
integers, if there is no fractional part.
So LwM2M engine cannot assume from the path that
the incomming number is either float or int. Accept both.

Don't push the TS flag on `buf` itself.
This messes up the MTU calculations: a packet that would exactly fit the
MTU and has a timestamp would be unnecessarily fragmented.
The MTU check is done on `buf` as a whole. At the point where the
fragmentation length is decided, `buf` includes one extra byte to pass the
TS bit around. That byte shouldn't count towards the MTU.
Instead, infer the presence of the timestamp by inspecting the amount of
headroom that the buffer has. This works because we always reserve
enough memory to push the timestamp, but not always push a timestamp on
the buffer. #tightlycoupled
This method is slightly uglier IMO, but eases MTU confusion and doesn't
rely on user_data.

When socket errors call sm_handle_timeout_state() we might be
in a state where application assumes we are in registered state
but we are dropping it.
Therefore we must ensure that all registration states emit either
REGISTRATION_TIMEOUT event for application to indicate that
we have lost the connection to server.

Revise data type declarations to avoid implicit/explicit casts:
- Changed `unsigned char` to `uint8_t` for `zeros` array
to match with `longest`.
- Declared variables `i`, `j`, and `pos` as `int` to use the same type.
- Cast `value` to `uint16_t` instead of `uint32_t` since
`value` is `uint16_t`.
- Moved `bh` and `bl` declarations to narrow the scope of variables.

number of counters have changed in gcc 14 by commit

Specifically, a new counter was added in gcc/gcov-counter.def:
```
/* Conditions. The counter is interpreted as a bit-set. */
DEF_GCOV_COUNTER(GCOV_COUNTER_CONDS, "conditions", _ior)
```
which in turn updates the value of GCOV_COUNTERS that is defined in

```

If only 2 page frames are queued and code executing in one frame is
making an access to memory in the second frame then the access will trap
and k_mem_paging_eviction_accessed() will be called to move that frame
to the end of the queue ... marking the new head frame unaccessible.
But that newly unaccessible frame contains the code that has yet to be
resumed to perform its memory access. Since it is now unaccessible, a
trap is triggered, the frame is moved to the end of the queue and the
new head frame (the one we trapped for initially) is marked unaccessible.
Execution is resumed with the memory access which is unaccessible again
and the cycle repeats infinitely.
Fix this by not marking the new head unaccessible if there is only one
queued frame left in the queue.

When an ISO stream fails to sync to a broadcaster within the first 6
