Gerard Marull-Paretas 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
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)
```

Network Statistics Sample Application
#####################################

Overview
********

This sample shows how to query (and display) network statistics from a user
application.

The source code for this sample application can be found at:
:zephyr_file:`samples/net/stats`.

Requirements
************

- :ref:`networking_with_host`

Building and Running
********************

A good way to run this sample application is with QEMU or native_posix board
as described in :ref:`networking_with_host`.

Follow these steps to build the network statistics sample application:

.. zephyr-app-commands::
   :zephyr-app: samples/net/stats
   :board: <board to use>
   :conf: prj.conf
   :goals: build
   :compact:

If everything is configured correctly, the application will periodically print
current network statistics to the console.

.. code-block:: console
