The source file for most single-file sample apps is usually
`main.c`. Rename this file to be consistent with other
samples.

* use `read()` instead of `recv()`
* use `write()` instead of `send()`
* use `CONFIG_POSIX_API` and drop `<zephyr/posix/..>` prefix
* use `perror()`
* fix `Makefile.posix` to use `CC` instead of `CXX`
* fix race condition which caused an unhandled EOF
and infinite loop, by adding a readback / echo
* Updated the docs to reflect the expected stdout
* Improve doc clarity

samples should not use CONFIG_TEST_EXTRA_STACK_SIZE, instead, they
should set the recommended stack size directly.

In the Zephyr implementation, `sem_timedwait()` uses a
potentially wildly different timebase for comparison via
`k_uptime_get()` (uptime in ms).
The standard specifies `CLOCK_REALTIME`. However, the real-time
clock can be modified to an arbitrary value via clock_settime()
and there is no guarantee that it will always reflect uptime.
This change ensures that `sem_timedwait()` uses a more
consistent timebase for comparison.

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)

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

Replace all calls to the assert macro that comes from libc by calls to
__ASSERT_NO_MSG(). This is usefull as the former might be different
depending on the libc used and the later can be customized to reduce
flash footprint.

This provides a better error message when building with CMake and
forgetting ZEPHYR_BASE or not registering Zephyr in the CMake package
registry. See parent commit for more details (split from parent for
better readability).

Support for the socketpair(2) system call was recently
added for 2.3.0 .
This change adds a sample application that demonstrates
how it can be used.
