The pointers to resource values should not be used
directly to update the values.
This will break observations if the server is trying to
observe changes during a software update.

This commit adds an implementation of MQTT-SN v1.2.
The specification is available on oasis-open.org:
https://www.oasis-open.org/committees/download.php/66091/MQTT-SN_spec_v1.2.pdf
The following things are missing in this implementation:
- Pre-defined topic IDs
- QoS -1 - it's most useful with predefined topics
- Gateway discovery using ADVERTISE, SEARCHGW and GWINFO messages.
- Setting the will topic and message after the initial connect
- Forwarder Encapsulation

Added support for handle case when all data is not possible to
add in 1 message for Send and Observed Notification.
Notification continuous pending timeseries data is triggred
by iMIN attribute.
Send Operation generate continuous message in multiple lwm2m

Normal Read by server only report back latest stored data.

Using a socketpair for communication in an ISR is not a great
solution, but the implementation should be robust in that case
as well.
It is not acceptible to block in ISR context, so robustness here
means to return -1 to indicate an error, setting errno to `EAGAIN`
(which is synonymous with `EWOULDBLOCK`).

Some minor housekeeping prior to adding an http server
implementation. There are already a number of http headers
and that number will likely increase with subsequent work.
Moving them into a common directory cleans up the

By using CONFIG_LWM2M_VERSION_1_0, the function
lwm2m_engine_get_binding() returns the binding
and the queue mode bytes. Therefore the buffer
must be tree bytes long.
The issue is caused by the two inconsistent defines:
lwm2m_registry.c:
#define BINDING_OPT_MAX_LEN 3 /* "UQ" */
lwm2m_rd_client.c:
#define CLIENT_BINDING_LEN sizeof("U")

Allows filling up struct lwm2m_obj_path by a macro.
For example:
struct lwm2m_obj_path p1 = LWM2M_OBJ(MY_OBJ);
struct lwm2m_obj_path p2 = LWM2M_OBJ(MY_OBJ, 0, RESOURCE);
Similarly, some function calls accept the structure, so it can
be initialized from stack and given by a pointer
lwm2m_notify_observer_path(&LWM2M_OBJ(obj_id, 0, RESOURCE_ID));

Minor change, the semaphore is freed by a caller so it was always
free, but just for being correct, it should be a blocking call,
so any errors would clearly block.

CoAP layer handles retrying so having a second layer of retry

This is a follow-up to commit a418ad4bb4.
Since the path to zephyr_mbedtls_priv.h is added to include directories
only when CONFIG_MBEDTLS_BUILTIN is enabled, the inclusion of the file
needs to be done under the same condition. Otherwise, an error occurs
when socket_tls.c is compiled without CONFIG_MBEDTLS_BUILTIN.
