This sample application simulates a network router with several
interfaces which performs IP Header Validation(calculation
of CRC16 header checksum). Each interface is represented
by sender queue(initialized with packet headers) and receiver queue.
Every header first is fetched from sender queue, than the header
CRC16 is calculated, and finally if hashsum is correct
the header is stored in receiver queue.
Each interface is can be processed independently by multiple threads.
This application can be used for testing the correctness
of synchronization mechanisms on multi-core systems.

This fixes the documentation instructions for building the SMP Pi
sample program, which incorrectly listed an underscore instead of
a path separator slash.

This provides a better error message when building with CMake and
forgetting ZEPHYR_BASE or not registering Zephyr in the CMake package
registry. See parent commit for more details (split from parent for
better readability).

Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

This was silently corrupting memory on x86-64.
Enable CONFIG_TEST so that this is detected properly,
and increase the stack size appropriately.

The seasonal overhaul of test identifiers aligning the terms being used
and creating a structure. This is hopefully the last time we do this,
plan is to document the identifiers and enforce syntax.
The end-goal is to be able to generate a testsuite description from the
existing tests and sync it frequently with the testsuite in Testrail.

Mark the old time conversion APIs deprecated, leave compatibility
macros in place, and replace all usage with the new API.

This sample showcases efficient utilization of SMP system
with processing of independent resource-hungry workloads.
With no cross-dependencies between workers and no usage of shared
resources (during heavy-lifting itself) we may demonstrate almost
linear scaling of efficiency. I.e. 2 cores do the same amount of
calculations twice faster than only 1 core. 4 cores complete
the same calculations 2 times faster than 2 cores.
