504cc436dd net: mqtt: Close the socket right after sending disconnect message
After sending the MQTT disconnect message, no response is expected,
therefore it makes little sense to delay the socket closure.

So far it was expected to call `mqtt_input` function after calling
`mqtt_disconnect` in order to close the socket, which is
counter-intuitive. Simplify this, by closing the socket rightaway
in the `mqtt_disconnect` function.

b3a1ede830 net: openthread: Use settings subsystem
OpenThread settings implementation built on top of Zepyhr settings
submodule.

With this solution, OpenThread settings are identified with keys of
the following format: `ot/id/instance`, where `id` is assigned by
OpenThread stack, and `instance` is a 32-bit random number, both in
hex. The implementation makes use of `settings_load_subtree_direct`
function to iterate over settings instances. This allows the
OpenThread settings layer to be a fully transparent shim layer between
OpenThread/Zephyr APIs.

662ee8eacf net: buf: Switch from net buf assert to system assert
Remove net bufs own assertion mechanism and use the system assert
instead. This changes the assertion messaged printed from printing
expression to printing the line and file name. This provides more
context as the same expression could be asserted upon multiple times and
would then not provide enough clarity in the message.

This removes the option to enable only net buf assertions.

caa06c9c48 net: lwm2m: add optional timestamp resources to some IPSO objects
Based on work by Michael Scott.

Add a new Kconfig knob, CONFIG_LWM2M_IPSO_TIMESTAMP_EXTENSIONS. This
defaults to n. When enabled, various IPSO objects will by default have
the timestamp resource (5518) added to their representations. This can
be turned off on a per-object basis.

The idea of adding timestamp resources was originally suggested by
Hannes Tschofenig on this OMA page:
