This test was written to assume that on idle the CPU would wake up on
the next tick boundary because of the timer interrupt. No such
interrupt arrives in tickless mode and it hangs forever.
A more whiteboxy test involving setting a clock timout will have to be
written for this feature if we want to keep it on tickless systems.
Alternatively we could move this test out of tests/kernel/context and
always disable tickless.

The theory behind this test seems to be that taking an IRQ lock should
prevent the advance of the kernel's tick counter. That works on
traditional timers only. In tickless mode the timer hardware/driver
is expected to be able to give us an answer for time independent of
interrupt delivery, so the test fails spuriously. The "bug" detected
is a feature of tickless!

I was pretty careful, but these snuck in. Most of them are due to

This test needs just a tiny bit of extra stack. 512 bytes isn't
enough on x86 with the most recent set of timer patches.

If the idle code was detecting that it needed to sleep for less than
CONFIG_SYS_TICKLESS_IDLE_THRESH, then it would never call
z_clock_set_timeout() at all, which means that the system would never
wake up unless it already had a timeout scheduled! Apparently we
lacked a test case to detect this condition.
Honestly this seems like a crazy feature to me. There's no benefit in
delivering needless tick announcements. If the system has the
capacity to enter deeper sleep for long timeouts, that's already
exposed via the PM APIs, the timer subsystem needn't be involved.
But... we actually have a test (tickless_concept) that looks at this,
so support it for now and consider deprecation later.

The system tick count is a 64 bit quantity that gets updated from
interrupt context, meaning that it's dangerously non-atomic and has to
be locked. The core kernel clock code did this right.
But the value was also exposed to the rest of the universe as a global
variable, and virtually nothing else was doing this correctly. Even
in the timer ISRs themselves, the interrupts may be themselves
preempted (most of our architectures support nested interrupts) by
code that wants to set timeouts and inspect system uptime.
Define a z_tick_{get,set}() API, eliminate the old variable, and make
sure everyone uses the right mechanism.

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.
Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
The existing API defined sys_clock_{hw_cycles,ticks}_per_sec as simple
"variables" to be shared, except that they were only real storage in
certain modes (the HPET driver, basically) and everywhere else they
were a build constant.
Properly, these should be an API defined by the timer driver (who
controls those rates) and consumed by the clock subsystem. So give
them function syntax as a stepping stone to get there.
Note that this also removes the deprecated variable
_sys_clock_us_per_tick rather than give it the same treatment.

The $srctree environment variable gives the path relative to which
'(o)source' statements work (the current directory is used if $srctree
is unset). It is set to $ZEPHYR_BASE in cmake/kconfig.cmake, so there's
no need to qualify the source of Kconfig.zephyr in sample Kconfig files
(or in external projects).
All 'source's in Zephyr assume that the Zephyr root directory is used as
the srctree as well, and would break otherwise.
Remove the $(ZEPHYR_BASE)s to make it clearer that all 'source'
statements work relative to the Zephyr root. There was some user
confusion on IRC.
Also explain how things work in the documentation.

With the new Kconfig preprocessor (described in
https://github.com/torvalds/linux/blob/master/Documentation/kbuild/
kconfig-macro-language.txt), the syntax for expanding environment
variables is $(FOO) rather than $FOO.
$(FOO) is a general preprocessor variable expansion, which falls back to
environment variables if the variable isn't set (like in Make). It can
also be used in prompts, 'comment's, etc.
The old syntax will probably be supported forever in Kconfiglib for
backwards compatibility, but might as well make it consistent now that
people might start using the preprocessor more.

The BT threads are interfering with the main thread priority selection
and the test fails semi-spuriously on NRF5x boards with "threads ran
too soon" (i.e. not an EDF failure per se, but the fact that the new
threads at K_LOWEST_APPLICATION_PRIO are running instead of the test
thread). This is a reasonable workaround for testing the
SCHED_DEADLINE ordering behavior, though.

Building with !MULTITHREADING is designed for bootloaders and similar
minimal-functionality use cases. It's pathologically silly to combine
it with MMU drivers and address space partitioning, even though on
some architectures that technically works (on ARM, it seems not to).
The test intent was to disable this originally, but it turns out that
doesn't work. There is a TEST_USERSPACE kconfig symbol that also
needs to be explicitly turned off, otherwise it will reselect
USERSPACE against our wishes.

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.
