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.

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 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)
```

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.

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.
