mbedTLS log level is obviously a mbedTLS config setting. It makes
sense to have it defined in mbedTLS Kconfig, and different parts
of Zephyr to reuse as needed (e.g. net-app vs upcoming TLS wrapper
for sockets).

Create a net sample to setup a multi-node RPL mesh network using QMEU.
To enable this, it was necessary implement a hw filter on IEEE 802.15.4
UART Pipe driver and create a QEMU pipe management on cmake.
This sample use a tool developed on zephyr net-tools repository called
virtual-hub.

The Host header is even mandatory in HTTP 1.1, and indeed without
it, many virtual hosting setups don't work (which are many), so to
be faithful to what README says: "You can edit the source code to
issue a request to any other site on the Internet", let's
complicate the sample by including it.

This sample downloads a more or less big file (~6MB as preconfigured)
over HTTP and checks its hash for integrity. It also repeat such a
download indefinitely, counting total number of bytes transferred.
This is thus a kind of traffic load testing sample. (Ported to C
from MicroPython original).

The previous default, "config-threadnet.h", is more or less arbitrary
choice made in a commit 312def2c78 1.5 years ago. In particular,
it's not related to Thread support in Zephyr per se (there was no
such support at that time).
It doesn't make sense to have a default intended for a particular,
not widely used (yet) protocol. Instead, the default should work
out of the box with a contemporary widely deployed arrays of TLS
servers, which are HTTPS server. config-mini-tls1_2.h works with
https://google.com, and by extension, with many other servers on
the Internet.
So, have that as the default, and let applications with special
needs to override that to what they need.

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)).

Redesign of the net_buf_simple and net_buf structs, where the data
payload portion is split to a separately allocated chunk of memory. In
practice this means that buf->__buf becomes a pointer from having just
been a marker (empty array) for where the payload begins right after
the meta-data.

and print various statistics like number of packets received and
dropped, amount of bytes received, and how many packets / sec
we were able to receive.

Right now in FIN_WAIT1 state, if we receive FIN+ACK message, then
tcp state changed to FIN_WAIT2 on ACK flag and immediately on FIN
flag state changed to TIME_WAIT. Then final ACK is prepared and sent
(in queue at-least) to peer. Again immediately state changed to
TCP_CLOSED, where context is freed. net_context_put frees context
and releases tcp connection. Final ACK packet which is in queue
is dropped.
As a side effect of freed ACK packet, peer device keep on sending
FIN+ACK messages (that's why we see a lot of "TCP spurious
retransimission" messages in wireshark). As a result
of context free (respective connection handler also removed), we see
lot of packets dropped at connection input handler and replying with
ICMP error messages (destination unreachable).
To fix this issue, timewait timer support is required. When tcp
connection state changed to TIMEWAIT state, it should wait until
TIMEWAIT_TIMETOUT before changing state to TCP_CLOSED. It's
appropriate to close the tcp connection after timewait timer expiry.
Note: Right now timeout value is constant (250ms). But it should
be 2 * MSL (Maximum segment lifetime).
