0b90fd5adf samples, tests, boards: Switch main return type from void to int
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.

79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
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.

a202341958 devices: constify device pointers initialized at compile time
Many device pointers are initialized at compile and never changed. This
means that the device pointer can be constified (immutable).

Automated using:

```
perl -i -pe 's/const struct device \*(?!const)(.*)= DEVICE/const struct
device *const $1= DEVICE/g' **/*.c
```

Move to use DEVICE_DT_GET_ONE instead of device_get_binding as

c7b5b3c419 samples: migrate includes to contain <zephyr/...> prefix
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

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)

d1a93c1426 drivers: sensor: Const sensor trigger data in trigger handler
This commit adds const modifier in second argument for
sensor trigger handler.
There is no reason to modify this data and this change
would allow to store trigger configuration also in FLASH.

Fixes: #38929

Now that device_api attribute is unmodified at runtime, as well as all

A coccinelle rule is used for this:

a49b364244 drivers: sensor: sht3xd: convert to new GPIO APIO
Update ALERT active level in all devicetree files.  Capture GPIO flags
in static configuration.  Add internal API to enable and disable
interrupt, to release the handlers when an alert occurs, and to
re-enable the signal when the handler completes.  Check for alerts
received during periods when the interrupt was disabled.

Extend the example to handle both above and below range triggers and
alerts that are present on startup.
