This test uses ztest anyway, the default should be fine
just like any other test running under ztest.
k_thread_create() uses a lot of stack, and the main
stack size is very small if ztest is enabled. Do it in
another ztest task instead.
We don't need to mess with the main thread's priority,
just have the alt thread run cooperatively.

The various struct pipe_sequence were not located in memory
accessible to user mode. With optimization turned on, they
weren't in memory at all, but with code coverage enabled
the arrays were actually being read, resulting in memory
access failures from user mode.
Fix them by placing in ROM, they never get modified.

device_get_binding() compares pointers first before doing strcmp().
However, enabling coverage forces -O0 to disable any compiler
optimizations. There would be multiple copies of the same string,
and the code pathing doing pointer comparsion would not be tested
at all. So add this flag to merge string constants such that
the pointer comparison would be exercised.
This also adds a bad driver which fails initialization. This is
to make sure that execution path is covered.

The NSIM emulator has severe performance issues when
the MPU registers are reprogrammed on context switch.
Disable runtime reprogramming of the MPU for these
platforms on these two tests, which have a lot of context
switch thrashing. This is done by ensuring userspace
and hardware stack overflow detection via guard areas
is disabled.
I have assurances from the ARC team that the tests run fine
on real hardware and this is an emulation issue.
For 1.15, this will be completely resolved by optimizing
MPU region gap-filling to not take place during context
switch time, which will drastically reduce the number of
MPU registers poked during context switch on nsim_sem.
Meanwhile, for 1.14 we ensure that no runtime reprogramming
of the MPU is done for these tests.

Unlike CONFIG_HW_STACK_PROTECTION, which greatly helps
expose stack overflows in test code, activating
userspace without putting threads in user mode is of
very limited value.
Now CONFIG_TEST_USERSPACE is off by default. Any test
which puts threads in user mode will need to set
CONFIG_TEST_USERSPACE.
This should greatly increase sanitycheck build times
as there is non-trivial build time overhead to
enabling this feature. This also allows some tests
which failed the build on RAM-constrained platforms
to compile properly.
tests/drivers/build_all is a special case; it doesn't
put threads in user mode, but we want to ensure all
the syscall handlers compile properly.

This macro is slated for complete removal, as it's not possible
on arches with an MPU stack guard to know the true buffer bounds
without also knowing the runtime state of its associated thread.
As removing this completely would be invasive to where we are
in the 1.14 release, demote to a private kernel Z_ API instead.
The current way that the macro is being used internally will
not cause any undue harm, we just don't want any external code
depending on it.
The final work to remove this (and overhaul stack specification in
general) will take place in 1.15 in the context of #14269Fixes: #14766

The 14 individual cases that use these four config files are now

Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
For obvious performance reasons, scheduler state changes (other than
aborting a thread) do not cause synchronous interrupts on the other
CPU. Doing a k_thread_wakeup() means that the current CPU will run it
synchronously if it's high priority, but if you want to see it run on
the other cores you need to wait for them to reach a scheduling point
on their own.
The test was written to assume that k_thread_wakeup() is synchronous,
but that's not right, and it needs to spin a bit. This bug was always
present in the test, but masked by a bug in the way that k_sleep() was
handled on SMP. See #9506.

A few more test cases that are measurably unreliable when run in SMP.
For the most part these work most of the time (though the semaphore
