Platforms that support IPIs allow them to be broadcast via the
new arch_sched_broadcast_ipi() routine (replacing arch_sched_ipi()).
Those that also allow IPIs to be directed to specific CPUs may
use arch_sched_directed_ipi() to do so.
As the kernel has the capability to track which CPUs may need an IPI
(see CONFIG_IPI_OPTIMIZE), this commit updates the signalling of
tracked IPIs to use the directed version if supported; otherwise
they continue to use the broadcast version.
Platforms that allow directed IPIs may see a significant reduction
in the number of IPI related ISRs when CONFIG_IPI_OPTIMIZE is
enabled and the number of CPUs increases. These platforms can be
identified by the Kconfig option CONFIG_ARCH_HAS_DIRECTED_IPIS.

The CONFIG_IPI_OPTIMIZE configuration option allows for the flagging
and subsequent signaling of IPIs to be optimized.
It does this by making each bit in the kernel's pending_ipi field
a flag that indicates whether the corresponding CPU might need an IPI
to trigger the scheduling of a new thread on that CPU.
When a new thread is made ready, we compare that thread against each
of the threads currently executing on the other CPUs. If there is a
chance that that thread should preempt the thread on the other CPU
then we flag that an IPI is needed for that CPU. That is, a clear bit
indicates that the CPU absolutely will not need to reschedule, while a
set bit indicates that the target CPU must make that determination for
itself.

Until recently, the posix api was purely a consumer of the
network subsystem. However, a dependency cycle was added as
a stop-gap solution for challenges with the native platform.
Specifically,
1. eventfd symbols conflict with those of the host
2. eventfd was excluded from native libc builds via cmake
If any part of the posix were then to select the network
subsystem (which is a legitimate use case, given that networking
is a part of the posix api), we would get a build error due to
the Kconfig dependency cycle.
As usual, with dependency cycles, the cycle can be broken
via a third, mutual dependency.
What is the third mutual dependency? Naturally, it is ZVFS
which was planned some time ago. ZVFS will be where we
collect file-descriptor and FILE-pointer APIs so that we can
ensure consistency for Zephyr users.

ZVFS_EVENTFD_MAX.

Zephyr's POSIX API is moving toward using the standard
nomenclature from IEEE 1003.1-2017 for as much as possible. In
particular, we want to have consistent naming between Zephyr's
POSIX API Kconfig options and the naming for POSIX Options and
Option Groups.
The Kconfig option CONFIG_PTHREAD_IPC has been (ab)used for a
very long time for a variety of different purposes. However,
the standard Option / feature test macro for POSIX Threads is,
intuitively _POSIX_THREADS. There is a corresponding sysconf()
key named _SC_POSIX_THREADS.
Annoyingly, the POSIX Option Group that corresponds to the
Option is POSIX_THREADS_BASE, which is a minor inconsistency
in the standard.
The _POSIX_THREADS Option already includes mutexes, condition
variables, and thread-specific storage (keys). So with this
change, we also deprecate the redundant Kconfig variables that
do not have a corresponding match in the standard.
- CONFIG_PTHREAD_IPC
- CONFIG_PTHREAD
- CONFIG_PTHREAD_COND
- CONFIG_PTHREAD_MUTEX
- CONFIG_PTHREAD_KEY
Additionally, create Kconfig variables for those configurables
which we are lacking:
- CONFIG_POSIX_THREADS_EXT
- CONFIG_POSIX_THREAD_ATTR_STACKSIZE
- CONFIG_POSIX_THREAD_ATTR_STACKADDR
- CONFIG_POSIX_THREAD_PRIORITY_SCHEDULING
- CONFIG_POSIX_THREAD_PRIO_INHERIT
- CONFIG_POSIX_THREAD_PRIO_PROTECT
- CONFIG_POSIX_THREAD_SAFE_FUNCTIONS
Some Kconfig variables were renamed to more properly match the spec:
- CONFIG_MAX_PTHREAD_COUNT -> CONFIG_POSIX_THREAD_THREADS_MAX
- CONFIG_MAX_PTHREAD_KEY_COUNT -> CONFIG_POSIX_THREAD_KEYS_MAX

The POSIX_MAX_FDS option does not correspond to any standard

Zephyr's POSIX Kconfig variables correspond to those defined in
