This migrates the subsys code samples to the new Sphinx code-sample
extension, making it easier to find relevant samples when browsing
API reference.

Add new sample scenario without using a hardware watchdog as fallback.
This is used for the moment only for the mr_canhubk3 board, but a
generic configuration is introduced that can be used by other boards if
needed.

Twister now supports using YAML lists for all fields that were written
as space-separated lists. Used twister_to_list.py script. Some artifacts
on string length are due to how ruamel dumps content.

As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.
Most of these changes were automated using coccinelle with the following
script:
@@
@@
- void
+ int
main(...) {
...
- return;
+ return 0;
...
}
Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

Starting with commit b9b43a0eb772a464bba13833d11e3a31fbf4e09e, printk()
messages are handled by the logging subsystem. This can cause trouble
in watchdog related samples if the deferred logging mode is used (and
currently it is by default), because those samples are ended by a reset
and some messages may not get a chance to be outputted.
Since the same problem concerns also the ordinary logging messages that
may be produced during execution of the samples, this commit fixes it
by switching to the immediate logging mode, not by just disabling the
LOG_PRINTK option.

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.

When no hardware device is available, set WDT_NODE to DT_INVALID_NODE.
Also switch to a single initializer using DEVICE_DT_GET_OR_NULL so that
we can constify the pointer.

In order to bring consistency in-tree, migrate all samples to the use
the new prefix <zephyr/...>. Note that the conversion has been scripted:
```python
from pathlib import Path
import re
EXTENSIONS = ("c", "h", "cpp", "rst")
for p in Path(".").glob("samples/**/*"):
if not p.is_file() or p.suffix and p.suffix[1:] not in EXTENSIONS:
continue
content = ""
with open(p) as f:
for line in f:
m = re.match(r"^(.*)#include <(.*)>(.*)$", line)
if (m and
not m.group(2).startswith("zephyr/") and
(Path(".") / "include" / "zephyr" / m.group(2)).exists()):
content += (
m.group(1) +
"#include <zephyr/" + m.group(2) +">" +
m.group(3) + "\n"
)
else:
content += line
with open(p, "w") as f:
f.write(content)

For consistency with the scheme used for other nRF peripherals,
use the peripheral name that nRF Product Specifications use.
In this case, it is WDT, not WATCHDOG.
Also remove the requirement for the label property in the binding.
It is no longer needed.

MCUX watchdog timer supports min window of 500ms. Increase maximum task
watchdog timeout window to 500ms by default, so that this sample can run
on iMX RT SOCs. Also update iMX RT watchdog driver to reject timeout
maximums under 500ms with a useful error message

The task_wdt_init() API can fail to install a timeout for the fallback
hardware WDT (hw_wdt) without returning an error code. This patch
enables task_wdt_init() to return the hw_wdt install timeout error code
if the hw_wdt install timeout fails.

Move to CMake 3.20.0.
At the Toolchain WG it was decided to move to CMake 3.20.0.
The main reason for increasing CMake version is better toolchain
support.
Better toolchain support is added in the following CMake versions:
- armclang, CMake 3.15
- Intel oneAPI, CMake 3.20
- IAR, CMake 3.15 and 3.20

Use the actual minimum timeout used by the sample for task watchdog
channels (100 ms) as the configuration value for the fallback hardware
watchdog, to avoid unnecessary executions of the timer handler.
Add missing indentation in the documentation of the sample so that
the console output is rendered correctly.
