Andrew Boie 7b1ee5cf13 tests: CONFIG_TEST_USERSPACE now off by default
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.

Fixes: #15103 (and probably others)

Andy Ross a4614372f9 tests: Mass SMP disablement on non-SMP-safe tests
(Chunk 3 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.

Andrew Boie 2b9b4b2cf7 k_queue: allow user mode access via allocators
User mode may now use queue objects. Instead of embedding the kernel's
linked list information directly in the data item, a container struct
is allocated from the caller's resource pool which is then added to
the queue. The new sflist type is now used to store a flag indicating
whether a data item needs to be freed when removed from the queue.

FIFO/LIFOs are derived from k_queues and have had allocator functions
added.
