This change to the shell API enables the user to retrieve the
return code of the most recently run shell command. This is
useful both for users wanting specific information beyond the print
statements in a command, but especially for automated users
that prefer a simple return code to parsing human readable text.
This was tested using all default shell commands, as well as
eeprom, flash, and i2c, where specific errors could be forced.
In all cases, the correct return value was returned by the new

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

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.

K_LOWEST_APPLICATION_THREAD_PRIO. Due to this all the other threads can
preempt the shell thread. Proposed solution is to add Kconfig which
gives the flexibility to change the priority of the shell thread.
This is now implemented using a new Kconfig variable
SHELL_THREAD_PRIORITY_OVERRIDE. By setting this option
SHELL_THREAD_PRIORITY can be set.

All variables for address, width and value are unsigned, so use strtoul
instead of strtol. This fixes an issue when 0xffffffff is about to be
assigned to specific address, which was truncated to 0x7fffffff so far.

Move all PM_DEVICE_STATE_* definitions to an enum. The
PM_DEVICE_STATE_SET and PM_DEVICE_STATE_GET definitions have been kept
out of the enum since they do not represent any state. However, their
name has not been changed since they will be removed soon.
All drivers and tests have been adjusted accordingly.

Added api call that can set a callback that is called whenever
data is received on shell. When callback is set, shell processing
is bypassed and data is passed to that callback.

Promote the "edac mem" shell subcommand to a generic "devmem" root shell

If the shell root command shall be set in the application, e.g. for
implementing a login scheme, it is an advantage to set this already
during shell init.
This is now implemented using a new Kconfig variable SHELL_CMD_ROOT.

The tabulator handler creates a single structure if it is handling
dynamic commands. If the currently processed dynamic command has a
dynamic subcommand they both share the same structure.
As a result tabulation operation may result in undefined behaviour.
As a solution, a new structure was introduced to keep subcommand
information.
Fixes#35926.

Allow time for the shell to successfully echo the reboot command input
before the reboot abruptly terminates it. n This can help external
systems that interact with the shell and require the reboot command's
echo to successfully complete to synchronise with the device.

When shell log backend was disabled fifo used only in
deferred mode was unconditionally flushed which lead to
errors in immediate mode where fifo was not present. On
the other hand, in case of LOG2_MODE_DEFERRED fifo (mpsc_pbuf)
was initialized in enable stage.
In order to clean things up, deferred v1 fifo flushing and
deferred v2 mpsc pbuf initialization were moved to fifo_reset
function which is called when shell log backend is enabled.

Remove this intrusive tracing feature in favor of the new object tracing
using the main tracing feature in zephyr. See #33603 for the new tracing
coverage for all objects.
This will allow for support in more tools and less reliance on GDB for
tracing objects.

When shell had too many pending log messages it was attempting to
drop expired messages and retrying to put the new message. There
was an assumption that enough messages are dropped and new message
can be put. It may not be the case if no message expired during
given time. Wrapped the operation in loop to continue until expired
message is freed and new message is enqueued.

Shell uninitialization is not synchronous, it is deferred to shell
thread so resources used by the shell (e.g. transport resource like
uart) cannot be used until it is completed. Added callback which
notifies when all resources are released and shell is uninitialized.
Callback is called from shell thread just before it is aborted.

The clock/timer APIs are not application facing APIs, however, similar
to arch_ and a few other APIs they are available to implement drivers
and add support for new hardware and are documented and available to be
used outside of the clock/kernel subsystems.
