This commit fixes the assertion in test_timer_remaining() that checks
whether the remaining ticks on a timer is less than or equal to half of
the timer duration after a busy wait of that time. If the timer
duration corresponds to an odd number of ticks, 1 should be added to
the upper bound given k_timer_remaining_ticks() returns
<ticks til next deadline> - <elapsed ticks>,
and <elapsed ticks> is truncated to closest integer tick count.
For example, if
dur_ticks = 3277
<ticks til next deadline> = 3277
<elapsed ticks> = 1638.5 rounded to 1638
rem_ticks would be 1639, which is 1 greater than dur_ticks/2.

The test of the absolute timeout feature was a simple whitebox test
that inspected the generated ticks field of different constructors for
identity. But it wasn't simple enough, because it was doing a
ticks->ms->ticks conversion (at compile time, sigh) on the input data,
which is obviously lossy on platforms where ticks are shorter than
milliseconds by non-integral factors.
Fix to do the conversion in just one direction.

This test sets a timer, busy waits for half the duration, and then
checks the remaining time is correct. And it correctly does all its
math in tick precision and aligns to a timer interrupt to eliminate
aliasing due to the tick stride.
But it's waiting using k_busy_wait(), not a timer: "half the duration"
in MICROSECONDS (for k_busy_wait()) is not necessarily representable
as an integer number of TICKS on all platforms. Because k_busy_wait()
always rounds up, we need one extra tick of buffer on those platforms.

Add support for "absolute" timeouts, which are expressed relative to
system uptime instead of deltas from current time. These allow for
more race-resistant code to be written by allowing application code to
do a single timeout computation, once, and then reuse the timeout
value even if the thread wakes up and needs to suspend again later.
Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them. Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:
+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
values for equality (e.g. with K_FOREVER or K_NO_WAIT).
+ Adding a k_msleep() synonym for k_sleep() which can continue to take
integral arguments as k_sleep() moves away to timeout arguments.
+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
generate timeout arguments.
+ Removing the usage of K_NO_WAIT as the final argument to
K_THREAD_DEFINE(). This is just a count of milliseconds and we need
to use a zero.
This patch include no logic changes and should not affect generated
code at all.

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.

Disabling SMP mode for certain tests was a one-release thing, done to
avoid having to triage every test independently (MANY are not
SMP-safe), and with the knowledge that it was probably hiding bugs in
the kernel.
Turn it on pervasively. Tests are treated with a combination of
flagging specific cases as "1cpu" where we have short-running tests
that can be independently run in an otherwise SMP environment, and via
setting CONFIG_MP_NUM_CPUS=1 where that's not possible (which still
runs the full SMP kernel config, but with only one CPU available).

The test_timer_periodicity waits for first timer expiration
in order to extract timer firing time. The wait is performed
using k_timer_status_sync() API call, which blocks thread
until timer expiration. However if the timer expired before
call the this function, it will return immediately, triggering
test failure.

- Some tests have a "userspace" tag pretending to TEST_USERSPACE but
don't and vice versa: fix missing or spurious "userspace" tags in
testcase.yaml files.
Tests have a _spurious_ "userspace" tag when they PASS this command
cause none should pass:
./scripts/sanitycheck --tag=userspace -p qemu_x86 \
--extra-args=CONFIG_TEST_USERSPACE=n \
--extra-args=CONFIG_USERSPACE=n | tee userspace.log
All tests run by this command must either fail to build or fail to run
with some userspace related error. Shortcut to look at all test
failures:
zephyr_failure_logs() {
awk '/see.*log/ {print $2}' "$@"
}
Tests _missing_ "userspace" tag FAIL to either build or to run with some
userspace related error when running this:
./scripts/sanitycheck --exclude=userspace -p qemu_x86 \
--extra-args=CONFIG_TEST_USERSPACE=n \
--extra-args=CONFIG_USERSPACE=n | tee excludeuserspace.log
Note the detection methods above are not 100% perfect because some
flexible tests like tests/kernel/queue/src/main.c evade them with #ifdef
CONFIG_USERSPACE smarts. Considering they never break, it is purely the
test author's decision to include or not such flexible tests in the
"userspace" subset.
