Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

(Chunk 1 of 3 - this patch was split across pull requests to address
CI build time limitations)
Zephyr has always been a uniprocessor system, and its kernel tests are
rife with assumptions and outright dependence on single-CPU operation
(for example: "low priority threads will never run until this high
priority thread blocks" -- not true if there's another processor to
run it!)
About 1/3 of our tests fail right now on x86_64 when dual processor
operation is made default. Most of those can probably be recovered on
a case-by-case basis with simple changes (and a few of them might
represent real bugs in SMP!), but for now let's make sure the full
test suite passes by turning the second CPU off. There's still plenty
of SMP coverage in the remaining cases.

The intent of this Kconfig is to allow libc stdout
functions like printf() to send their output to the
active console driver instead of discarding it.
This somehow evolved into preferring to use
printf() instead of printk() for all test case output
if enabled. Libc printf() implementation for both
minimal libc and newlib use considerably more stack
space than printk(), with nothing gained by using
them.
Remove all instances where we are conditionally
sending test case output based on this config, enable
it by default, and adjust a few tests that disabled
this because they were blowing stack.
printk() and vprintk() now work as expected for
unit_testing targets, they are just wrappers for
host printf().
Fixes: #13701

When using an IDE (e.g. Eclipse, Qt Creator), the project name gets
displayed. This greatly simplifies the navigation between projects when
having many of them open at the same time. Naming every project "NONE"
defeats this functionality.
This patch tries to use sensible project names while not duplicating
too much of what is already represented in the path. This is done by
using the name of the directory the relevant CMakeLists.txt file is
stored in. To ensure unique project names in the samples (and again, in
the tests folder) folder, small manual adjustments have been done.

This was another "global variable" API. Give it function syntax too.
Also add a warning, because on nRF devices (at least) the cycle clock
runs in kHz and is too slow to give a precise answer here.

Prepend the text 'cmake_minimum_required(VERSION 3.8.2)' into the
application and test build scripts.
Modern versions of CMake will spam users with a deprecation warning
when the toplevel CMakeLists.txt does not specify a CMake
version. This is documented in bug #8355.
To resolve this we include a cmake_minimum_required() line into the
toplevel build scripts. Additionally, cmake_minimum_required is
invoked from within boilerplate.cmake. The highest version will be
enforced.
This patch allows us to afterwards change CMake policy CMP000 from OLD
to NEW which in turn finally rids us of the verbose warning.
The extra boilerplate is considered more acceptable than the verbosity
of the CMP0000 policy.

The kernel incorrectly assumed, that system timer frequency is always
divisible without remainder by couple "natural" tick rates (like 100).
As result on some SoCs, time calculations was not correct, producing
strange effects (invalid sleep times, incorrect k_uptime_get() etc.).
This commit enables accurate, but costly (using 64-bit math) tick <-> ms
conversion if the selected tick interval is not exact due to hardware
limitations.
Also, this commit fixes tests in which removed _ms_per_tick were used.

For many tests, avoid splitting into files and put eveything in main.c.
For many of the tests, use main.c as the test source file to keep things
consistent.

Add a test to verify that k_sleep() can be used to put
the calling thread to sleep for a specified number of
ticks during system initialization.
This test is inspired from legacy test_early_sleep test
from v1.7.0 release.
