For platforms that select Kconfig option CONFIG_KERNEL_COHERENCE,
the receive buffer used in mq_timedreceive() must not be on the
stack. This is because the k_msgq that underlies the POSIX mqueue
will attempt to perform a direct to buffer copy from the sender
when there is a waiting reader.

`pthread_detach()` should not be able to be joined. A recent

There were a number of tests that started with `test_posix_..`.
The `test_` prefix is necessary, but the `posix_` part is self-

Exercise the following (which rely mainly on existing Zephyr
utilities)
* `pthread_spin_init()`
* `pthread_spin_destroy()`
* `pthread_spin_lock()`
* `pthread_spin_trylock()`
* `pthread_spin_unlock()`
Additionally, ensure that we do not leak spinlock descriptors.

In some cases, when GitHub CI is running several Qemu processes,
each with heavy loads, SMP tests have shown some flakiness. This
exhibits itself as something like
```
... pthread_pressure on qemu_riscv32 failed (Timeout)
```
That is actually not at all limited to POSIX or any particular
architecture, but is mainly to do with the host scheduler and
perhaps memory barrier operations being lost in ISA translation
by Qemu.
Collectively, we can refer to these issues as "scheduler noise".
To reduce scheduler noise in the `pthread_pressure` testsuite,
enable `CONFIG_PTHREAD_CREATE_BARRIER` in `testcase.yaml`.
Note: end-users will likely not experience the need to enable
this in `prj.conf`. E.g. the following basic test demonstrates
0 failures locallly.
```
TEST=tests/posix/pthread_pressure
twister --build-only -T $TEST &>/dev/null
FAIL=0
for ((i=0; i < 100; i++)); do
echo "Run $((i+1))/100"
twister --test-only -T $TEST &>/dev/null
if [ $? -ne 0 ]; then
FAIL=$((FAIL+1))
echo "Failed $FAIL times"
fi
done
echo "Failure Rate: $((FAIL))/100"
```

Previously pthread_barrier_t was implemented in terms of wait
queues and internal scheduler functions.
This introduced some obstacles and inconsistency. In order
to be more consistent, rely only on Zephyr's public API and
reuse as many concepts as possible.
Deprecate `PTHREAD_BARRIER_DEFINE()` since it's non-standard.

Recently, a race condition was discovered in `pthread_create()`
and `pthread_join()` that would trigger an assertion in
`kernel/sched.c` of the form below.
```
aborted _current back from dead
```
This was mainly observed in Qemu. Unfortunately, Qemu SMP
platforms exhibit a real and measurable "scheduler noise"
which makes testing rather difficult.

The `aborted _current back from dead` error may appear in this
particular test under Qemu (and in particular Qemu SMP) systems.
A small delay between `pthread_create()` and `pthread_join()`
is sufficient to mitigate the issue.

This test simply counts how many times `eventfd_read()`
and `eventfd_write()` can be called on an
`eventfd(0, EFD_SEMAPHORE | EFD_NONBLOCK)` file
descriptor.
Prior to the recent changes in `eventfd`, we were seeing
approximately < 1000 writes / s. However, the previous
`eventfd` implementation would fail this test with the
result that the number of successful reads was far greater
than the number of successful writes.
This should be impossible, and with the recent `eventfd`
changes that was fixed. Additionally, we are seeing an
increase in over 40x for non-blocking eventfd reads and
writes.
```

I: BOARD: qemu_riscv64_smp

Previously, the prototypical use case for `eventfd()` was not
possible in Zephyr due to a deadlock associated with the
`fdtable.c` `k_mutex`.
The prototypical use case for `eventfd()` is to make a
blocking call to `eventfd_read()` from one thread, and then
from another thread, call `eventfd_write()` to "wake up" the
reading thread.
This additional test case ensures that Zephyr supports the
prototypical `eventfd()` use case.
