As example of echo_async_select added recently shows, we no longer
need to define a logger unconditionally in each source file. These
samples are intended to show Zephyr compatibility with POSIX sockets
API, so the less there're differences between Zephyr vs POSIX
ifdefs, the better.

Don't include net_app.h and net_buf.h, the first is deprecated, the
latter is low-level header, both shouldn't be used for socket apps.

Check result of fcntl() to catch any regressions in fcntl() handling
in Zephyr. To facilitate this, also merge block() and nonblock()
functions into single setblocking().

POSIX doesn't mandate such a header, only <fcntl.h>. <sys/fnctl.h>
is just an internal implementation detail of Newlib on which we should
not rely.
This makes it possible to build this sample against minimal libc.

Remove network specific default and max log level setting
and start to use the zephyr logging values for those.
Remove LOG_MODULE_REGISTER() from net_core.h and place the
calls into .c files. This is done in order to avoid weird
compiler errors in some cases and to make the code look similar
as other subsystems.

Initially this sample was intended to be very simple and schematic,
but as this sample going to become a base for stream API conversion,
time to handle all the edge conditions.

With 323e8cf069 applied and printf() working out of the box,
CONFIG_NET_BUF_LOG=y workarounds can be removed from configs of
all samples.
Also, print an intro message at the start of each server sample,
to give a user hint that the app didn't just hang and what to do
next. (The port waiting for connection is printed. We can't (easily)
print host address, because the samples should run on both Zephyr
and POSIX systems, and finding out local host address would require
hairy #ifdef's undermining the purpose of these samples (that is,
showing that the *same* code can be used on both types of systems)).

This helps to debug issues with mass connection handling (e.g. when
issues happen at ~500th connection).

The main reason is allowing to run on 6LoWPAN devices, though also to
demonstrate IPv6 support with BSD Sockets in general.
Tested on 96b_carbon.

Don't call net configuration explicitly, instead rely on net_app
auto init service.
Thus, the only difference between POSIX and Zephyr versions of these
samples are different include files. The application code is 100%
the same.
