A dangling `FIXME` comment was left in the `pthread.h` header
about how it would be difficult to implement
`PTHREAD_MUTEX_INITIALIZER` and `PTHREAD_COND_INITIALIZER`.
They were both implemented months ago, so let's retire
that comment.

Deprecate `EFD_IN_USE` and `EFD_FLAGS_SET` as they are not
specified as part of any public `eventfd()` API.
While those are being deprecated, use `_INTERNAL` variants.

TL;DR - a complete rewrite.
Previously, the prototypical `eventfd()` usage (one thread
performing a blocking `read()`, followed by another thread
performing a `write()`) would deadlock Zephyr. This shortcoming
has existed in Zephyr's `eventfd()` implementation from the
start and the suggested workaround was to use `poll()`.
However, that is not sufficient for integrating 3rd-party
libraries that may rely on proper `eventfd()` blocking
operations such as `eventfd_read()` and `eventfd_write()`.
The culprit was the per-fdtable-entry `struct k_mutex`.
Here we perform a minor revision of the locking strategy
and employ `k_condvar_broadcast()` and `k_condvar_wait()`
to signal and wait on the holder of a given `struct k_mutex`.
It is important to note, however, that the primary means of
synchronizing the eventfd state is actually the eventfd
spinlock. The fdtable mutex and condition variable are mainly
used for the purposes of blocking io (r,w,close) and are not
used in the code path of non-blocking reads.
The `wait_q` and `k_poll_signal` entries were removed from
`struct eventfd` as they were unnecessary.
Additionally, switch to using a bitarray because it is
possibly faster than linear search for allocating and
deallocating eventfd resources.

There is no major benefit to haveing `eventfd_read()` and
`eventfd_write()` as `static inline` functions and it is
arguably much easier to solve the deadlock bug when they
are not `inline`.

Complement the `struct k_mutex` in each fdtable entry
with a `struct k_condvar`. The reasoning for this should be
self-evident.
For a bit of history, `fdtable` was introduced in
commit 06eb489c45 ("kernel: add condition variables")
which predates `struct k_condvar`, introduced in
commit f484bbaa26 ("lib: posix: Implement generic file descriptor table")
by almost 2 years.
Additionally, provide a new accessor function,
`z_get_obj_lock_and_cond()`, that (optionally) gets the mutex
and condition variable associated with the provided object and
vtable.

Commit caea9dc196
("logging: Use TYPE_SECTION macros for log strings") changed to
use TYPE_SECTION macros for log strings. However, the data type
was changed from char[] to (char *), resulting in the pointer
to log strings are being put in the log_strings_area section
instead of the actual strings. Fix this by reverting the data
type change back to before that commit but semantically uses
TYPE_SECTION_ITERABLE() by expanding it manually.

Relax the expected behavior of the RX path. So far it was stated
that UART_RX_BUF_RELEASED event is generated when one buffer is
completely filled. Now, it is relaxed so that buffer can be
released even when not completed (e.g. after the first timeout).
This approach does not violate the API and may be more convenient
for some devices where on timeout a switch between DMA buffers
must occur.

The IEEE802154_2015 option is misleading, as it does not introduce full
802.15.4-2015 standard compliance but only random bits, plus it's
defined at the radio driver level, which brings yet another confusion.
Because of that, the option will be deprecated, and respective parts of
code that made use of it converted to use more specific configurations:
* nRF driver will now use CONFIG_NRF_802154_ENCRYPTION to specify
whether to compile in TX security
* net_pkt will only add extra 802.15.4 control block fields if
OpenThread is used, as they were solely used by this L2
* OpenThread radio layer will now use the OpenThread version to
determine whether to compile in TX security.

Only set a cpu as active (on pm subsystem) when the cpu is effectively
initialized. We cannot assume on pm subsystem that all cpus were
initialized since when the option CONFIG_SMP_BOOT_DELAY is used cpus are
initialized on demand by the application.

Support for multiple instances of a class implementation,
and the ability to register an instance to a configuration
at runtime, requires a mechanism to add a string descriptor
and update its index based on the total number of descriptors.
We also need to handle some special string descriptors like
Product or Serial Number provided by the application.
Marked as such by using specific macros, these descriptors
can be sorted out by the stack and the device descriptor
indexes are updated automatically.

All posix arch boards are required to provide the same
tracing/print API.
So, instead of having a different driver for native_posix and the
bsim boards, let's have a common one which uses this API.
This in turn results in the printk strings being printed in
the same underlaying backend as before with individual drivers.
A part from this, the native_posix console driver was a full
backend for the now long gone Zephyr console shell
(named legacy_shell from 527256501f
until it was retired in fd0b7f7767).
The whole input handling in this driver was dead code
