Seppo Takalo 05abdf5d0b net: lwm2m: Deprecate LWM2M_ENGINE_MESSAGE_HEADER_SIZE
Kconfig value LWM2M_ENGINE_MESSAGE_HEADER_SIZE added
an extra headroom for CoAP packet sizes so that
if CoAP Block-Wise transfer block-size is configured
to be same as LWM2M_COAP_MAX_MSG_SIZE, the full
payload block would usually fit to the datagram.

This causes too much confusion to be usable.
CoAP headers and options vary on sizes, and there is
no runtime limitations that we should check the
header size against.

Only real limitation is the CoAP packet size, which
must fit into the UDP datagram with typical DTLS headers.

Only limitation for CoAP block-size then is that
it must fit into the CoAP message with all the headers
and options. But as the option sizes, like path, vary,
it must be checked runtime.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
