Removes the `psa_crypto` sample from the current release, due to
PSA API conflicts that can not be immediately resolved between Zephyr's
instance of MbedTLS in the NS environment, and the TF-M PSA APIs
included when building with TF-M support.
PSA API changes upstream in MbedTLS 3.2.1 (used by TF-M 1.7.0), and
MbedTLS 3.1 (used in TF-M 1.6.0) need to be be resolved in both
upstream projects before this sample can be reintroduced.

There are scenarios when it is necessary to globally redefine
a log macro. The existing logging frontend is not sufficient since
it redirects at the function level.
One example is using pigweed_tokenzier. The pigweed tokenizer depends
on intercepting log strings at the macro level to function.
Introduce an option to include a custom application provided header
named "zephyr_custom_log.h" at the end of log.h. This allows an
application to extend the LOG_* macros globally.
This change includes a simple test that redefines the core LOG macros
to include a custom prefix.

The `TEST_RANDOM_GENERATOR` Kconfig symbol indicates that a non-random
number generator (i.e. a random number generator that is not truly
random) is _allowed_ to be used for testing purposes, and not
necessarily that a non-random number generator is _selected_ -- that is
indicated by the `RNG_GENERATOR_CHOICE` choices that depend on
`TEST_RANDOM_GENERATOR` (i.e. only `TIMER_RANDOM_GENERATOR` as of now).
This commit updates the `TEST_RANDOM_GENERATOR` Kconfig symbol
description to reflect and clarify that.
It also removes the `TEST_RANDOM_GENERATOR`'s dependency on
`ENTROPY_HAS_DRIVER` because the act of _allowing_ a non-random number
generator to be used does not depend on the availability of an entropy
driver -- when an entropy driver is available, by default, the
`ENTROPY_DEVICE_RANDOM_GENERATOR` will be selected; otherwise,
`TIMER_RANDOM_GENERATOR`, a non-random generator, will be selected.

Currently there is inconsistency in repository file names, APIs, Kconfig
options and documentation around file / file-system backend for settings
storage, as both "file" and "FS (file system)" are used. As an example,
there is `CONFIG_SETTINGS_FS` Kconfig option, but the file that implements
this settings backend is called `settings_file.c`. Another example are
names of static functions that implement settings storage API:
`settings_file_load()`, `settings_file_save()` and
`settings_fs_storage_get()`.
This backend is actually storing all settings in a single file, so it makes
sense to use "File" as the name of backend, instead of a more general
"FS" (which would make sense if several files would be used to store
settings).
Fix inconsistency in used wording in the tree and unify it to "settings
file backend". This naming is more precise to how the implementation looks.
It will also make it easier to grep through the codebase and analyze
existing code.
Deprecate settings_mount_fs_backend() function and all Kconfig options
starting with `CONFIG_SETTINGS_FS`.

Add zbus message bus as a Zephyr subsystem. No message bus
or communication abstraction other than the usual (message queues,
mailboxes, etc.) enabled developers to implement event-driven systems in
Zephyr quickly. Zbus would fill that gap by providing the community with
a lightweight and flexible message bus. The implementation tries to be
closest as possible to the existing ones. We use the claim/finish
approach, and the API for publishing and reading channels are similar
in message queues. Zbus is about channels, messages, and observers.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

A DMA friendly Stream API for zephyr. Based on ideas from io_uring
and iio, a queue based API for I/O operations.
Provides a pair of fixed length ringbuffer backed queues for submitting
I/O requests and recieving I/O completions. The requests may be chained
together to ensure the next operation does not start until the current
one is complete.
Requests target an abstract rtio_iodev which is expected to wrap all
the hardware particulars of how to perform the operation. For example
with a SPI bus device, a description of what a read, and write mean
can be decided by the iodev wrapping a particular device
hanging off of a SPI controller.
The queue pair are submitted to an executor which may be a simple
inplace looping executor done in the callers execution context
(thread/stack) but other executors are expected. A threadpool executor
might for example allow for concurrent request chains to execute in
parallel. A DMA executor, in conjunction with DMA aware iodevs
would allow for hardware offloading of operations going so far as to
schedule with priority using hardware arbitration.
Both the iodev and executor are definable by a particular
SoC, meaning they can work in conjuction to perform IO operations
using a particular DMA controller or methodology if desired.
The application decides entirely how large the queues are, where
the buffers to read/write come from (some executors
may have particular demands!), and which executor to submit
requests to.

Several tables in the section on POSIX support have a column
"Supported" which is supposed to indicate whether a feature,
a function, or similar, is supported in Zephyr or not. This
indication is done by placing character "+" in relevant cells.
However, in restructuredText, "+" is a sign for an element of
a bulleted list (as is the case with "*" and several other
characters). This, in turn, causes very inefficient rendering of
all these cells with "+", since restructuredText adds spacing
before and after any bulleted list.
Fix this by replacing all "+" characters by a simple "yes".
