When operating on different kinds of heaps sometimes there's a need to
perform special operations on heap, poweroff memory bank when releasing
memory etc. Therefore some additional data may be required.
Metadata is a point to keep such data.

The thread context test has insufficient checkings for failing
so add them:
() The variable rv for pass/fail is set but never checked. So
add a check to fail the test if such indicated.
() Each thread's pass variable is set to TC_FAIL (== 1) and
the check for successful thread execution simply checks
if pass variable is not zero, which is always true. So
change it so the check for failing condition is reasonable.

K_OBJ_MSGQ, K_OBJ_PIPE, and K_OBJ_STACK objects have pointers

returns these objects as uninitialized so when they are freed
there are random opportunities for freeing invalid memory
and causing random faults.

The K_OBJ_MSGQ object is unitialized so when the thread cleanup occurs
after an expected fault for invalid access the test case can randomly

On SMP, and especially using qemu on a busy system, it is possible for
a thread with a later timeout to get ahead of another one with an
earlier timeout. The tight timeout value difference (10ms) makes it
possible albeit difficult to reproduce. The result is something like:
|START - test_timeout_threads_pend_on_lifo
| thread (q order: 2, t/o: 0, lifo 0x4001d350)
|
| Assertion failed at main.c:140:
|test_multiple_threads_pending: (data->timeout_order not equal to ii)
| *** thread 2 woke up, expected 1
Let's make timeout values 10 times larger to make this unlikely race
even less likely.
While at it... The timeout field in struct timeout_order_data is some ms
value and not a number of ticks, so change the type accordingly.
And leverage k_cyc_to_ms_floor32() to simplify computation in
is_timeout_in_range().

Both alloc_pending tests requires the main thread to utilize
the heap so that child threads must pend on memory allocations.
However, the previous implementation was not SMP friendly where
the child threads could run and succeeded in memory allocation
on other CPUs while the main thread continued to allocate
memory. The main thread would fail to allocate memory if
the child thread (on other CPU) has not freed the memory yet.
Not to mention that, in this scenario, the child thread was not
pending on memory allocation which defeated the purpose of
the test. So to fix this, make sure the main thread allocates
enough memory so future allocations must go into pending.
Also, check that the child thread cannot allocation memory
when first entered so it is actually going into pending.

This test is already running with CONFIG_MP_NUM_CPUS=1. All those
1cpu declarations are needless. And some of them (like the init
tests) have side effects that make it difficult to do things like
"filter for only MP cases".
(Indeed, this is a heavily MP-unsafe test; almost all cases written to
rely on ordering between a parent thread and its child. And that's
doubly so for COHERENE platforms because lots and lots of the test
objects are on stacks. MP_NUM_CPUS=1 is definitely the right thing
here.)

This test is triggering some kind of bug that will reliably cause a
full host crash/hang of the x86 host environment on TGL/cAVS 2.5.
It's interfering with CI testing, so filter it out for now while we
figure it out.
Interestingly it doesn't have any trouble on older cavs15. And even
more so, it seems to be some kind of build interaction. If I disable
LOG=y, it passes. But when it fails, it actually fails BEFORE the boot
entry and core 0 initialization code is reached (i.e. LONG before any
logging initialization). Something is wrong with the generated file;
maybe a linker or rimage bug? The signature is reported OK by the
ROM, but that's the last we hear from the device before it blows up.

The test_queue_multithread_competition case wants to be sure that an
inserted item is recevied by the highest priority thread of several
waiting, but that only works if the threads aren't racing against each
other on different CPUs.
Also, the test_queue_loop case would produce a LOT of console output
very quickly. On a few occasions, I saw this overflow the 8k output
buffer of the intel_adsp devices at exactly the wrong time (with
respect to the polling loop in the host python script), cause a flush
of the stream, and then miss the SUCCESSFUL message. Quiet things
down a bit, there's not a lot of value of verbosity in a CI test.

These two cases use a k_pipe to transfer data, and do it (as is
customary) by copying into or out of buffers on the stack. But that
doesn't work when KERNEL_COHERENCE=y, because the pipe code has a
possibly-too-sophisticated zero copy implementation, and will do the
copy into the destination thread synchronously with the k_put_put()
call from the other CPU.
Normally the fix is to use a static buffer instead, but in this case
the buffers are shared between multiple simultaneous threads, so can't
be shared.
Just skip the tests, pending some rework to how they communicate.

The irq_lock() API is a legacy API not to be used for synchronization
by new code, and in any case is only being used in cargo-cult fashion
here. These test cases all do synchronous exceptions, there's
literally nothing to synchronize against.
(And in this case they're exposing a legacy wart. On platforms where:
1. SMP=y, which causes irq_lock() to be implemented as a somewhat
complicated global lock
2. No ARCH_EXCEPT() macro is defined, which causes the kernel to
use a fallback that simply aborts the current thread.
...this test will then abort a thread holding the lock, which will
cause it to be orphaned (if it weren't a legacy API, the kernel
should probably attempt to clean it up in k_thread_abort(), but it
is, and it doesn't), so the next attempt to lock it will hang.
And it's even worse, because this test builds with SMP=y and
MP_NUM_CPUS=1, so the hand will happen with interrupts masked on a
system with only one CPU, and everything will lock up solid.)

When CONFIG_TRACING_OBJECT_TRACKING is enabled, the kernel will keep
lists of some objects (detailed below), so that debuggers or other tools
can keep track of them.
The lists of objects are:
struct k_timer *_track_list_k_timer;
struct k_mem_slab *_track_list_k_mem_slab;
struct k_sem *_track_list_k_sem;
struct k_mutex *_track_list_k_mutex;

struct k_msgq *_track_list_k_msgq;
struct k_mbox *_track_list_k_mbox;
struct k_pipe *_track_list_k_pipe;
struct k_queue *_track_list_k_queue;
Note that while CONFIG_TRACING is needed, one can always use
CONFIG_TRACE_NONE=y. Also, tracking will only be done for objects that
are also being traced (so, to prevent tracking of some type of object,
such as k_timer, just make CONFIG_TRACING_TIMER=n).
