Added test to verify the spinlock acquisition fairness
in relation to the CPUs contending for the spinlock.
This test is only enabled for Ticket Spinlocks which
required to provide such kind of fairness.

On Intel boards (like intel_ehl_crb and intel_rpl_s_crb) for the
trylock_test some part is executed very fast and since there is no
synchronization, there might be situation when there is no
trylock_failures. Increasing time spend in this part fixes the issue.

Currently spinlock internals are directly accessed from the tests.
This way the test becomes bound to the particular spinlock implementation.
To remove this unnecessary dependency the distinct API to check if spinlock
is locked is introduced.
k_spin_is_locked should be used for the spinlock testing only,
so the scope of this API is intentionally restricted.

The test_trylock reuses the cpu1_thread, but there is no way for it to
exit. This will cause the thread created twice, as a result, two cpu
running the same thread simultaneously cause an unexpected crash.
Fix this by adding initialization of resources and also the exit for the
cpu1_thread.

Add a testcase to exercise two cases:
* when `k_spin_trylock()` fails (lock is busy)
* when `k_spin_trylock()` succeeds (lock is acquired)
We use the same machinery for checking for a recursive mutex
as `k_spin_lock()`.

The spin loop to ensure time goes past the timeout is done in terms
of the core clock, while the spin lock is timed on the system clock.
This difference is exasperated on systems where the core clock is much
faster than the system clock and the test failed. Add a significant
multiplier so the test works even when the system clock is much slower.

Spin locks must be in coherent memory for cavs. Initially this variable
was at the compilation unit scope but warnings about it being unused
from a twister run lead me to move it to be in the ifdef scope in the
function.
Move it back into the compilation units scope and wrap it in an
ifdef to ensure its not labeled as unused.

Spin locks held for any lengthy duration prevent interrupts and
in a real time system where interrupts drive tasks this can be

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

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 test was written very early. Spinlocks are required for SMP
implementation. They couldn't be tested in terms of it, so the test
used the low level MP API instead. But of course that breaks if SMP
is actually working and the CPU is already started.
No need for that now. Just spawn a thread like any other, and filter
the test to run only on SMP systems.

Update reserved function names starting with one underscore, replacing
them as follows:
'_k_' with 'z_'
'_K_' with 'Z_'
'_handler_' with 'z_handl_'
'_Cstart' with 'z_cstart'
'_Swap' with 'z_swap'
This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.
Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.
Various generator scripts have also been updated as well as perf,
linker and usb files. These are
drivers/serial/uart_handlers.c
include/linker/kobject-text.ld
kernel/include/syscall_handler.h
scripts/gen_kobject_list.py

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.

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.
