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
scripts/gen_syscall_header.py

This test was written to wait on a fifo with a timeout, return, and
check the timing between the start and end using k_cycle_get_32() to
see that it didn't run long. But timeouts expire on tick boundaries,
and so if tick expires between the start of the test and the entry to
k_fifo_get(), the timeout will take one full tick longer than expected
due to aliasing.
As it happened this passed everywhere except nRF (whose cycle timer is
32 kHz and thus more susceptible to coarser aliasing like this), and
even there it passed for a while until the spinlock validation layer
went in and added just enough time to the userspace code paths
(i.e. the code between the start time fetch and the point where the
fifo blocks takes longer) to open the window and push us over the
limit.
The workaround here is just to add a k_sleep(1) call, which is
guaranteed to block and wake up synchronously at the next tick.

(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.

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.

There is no guarantee of wake-up order when multiple threads
are woken up on the same tick. Hence, modified the tests
accordingly.
Fixes#8159.

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 return value from k_fifo_get() might be NULL in some situations,
so protect against that.

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 k_fifo kernel object timeout scenario tests like basic
k_fifo API tests with timeouts and tests which involve other
threads to get/put items from/into k_fifo with timeouts.
This test is inspired from test_stack legacy test from
Zephyr v1.7.0 release.
