UDP portion of the echo_client sends 1 packet with the sample data.
(TCP can send chunks of it depending on the response of the send()
function.) Not every network interface can send a UDP packet large
enough to handle the size of the sample data.
Let's make sure to account for the network interface MTU when deciding
the amount of sample data to send.

Add Kconfig option NET_SAMPLE_SEND_ITERATIONS that sets the number of
times the Zephyr echo client sample sends its data. By default the
value is zero, which means indefinite, and demonstrates the same
behavior as before.

Fixed bug in udp.c in echo_client and echo_server samples.
The bug causes UDP sockets to not close if socket id is 0.

PSK support is added to echo-client.c and echo-server.c.
If enabled, a header is included which contains the PSK.
If the default dummy PSK header is used, a warning is issued.
The header can be changed via Kconfig.

SOCKS5 support added to echo_client. Details are added
in README file about how to verify this feature using
echo-client with echo-server running on Linux host.

The `start_udp_and_tcp` funcion is a blocking function, therefore it
should not be called from the system workqueue, as it would stall it.
Because it was called in such a way, the retry mechanism, which
also relied on the system workqueue did not work properly.
This commit fixes the issue, by keeping the main application processing
in the main thread, and using a semaphore to synchronize with the
connection manager.

Start to monitor Connected and Disconnect events and then start
and stop the echo service according to system connectivity status.

Current application data size in echo_client sample does not fit into a
single datagram with DTLS enbled for default IPv6 MTU (1280 bytes). This
caused abrupt failure of the sample with DTLS enabled over 802.15.4 L2.
Decreasing the application data size allows it to fit into a single UDP
datagram after encapsulating it into DTLS record.
Additionally, finetune DTLS timeout on echo_server to match UDP
application timeout on echo_client (so that a single datagram loss
does not cauase DTLS session to end).

Use generic logging macros LOG_*() instead of NET_*() as the
latter are mostly meant for internal networking stack use.

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.

Add support for VLANs which are disabled by default.
The application can be configured to use the VLANs by setting
the IP addresses properly in config file. The VLAN support in
this sample application is only meant for testing multiple network
interface handling.
The application can be compiled like this for VLAN support:
cmake -DBOARD=qemu_x86 -DOVERLAY_CONFIG=overlay-vlan.conf ..

Per: http://pubs.opengroup.org/onlinepubs/009695399/functions/socket.html
"Upon successful completion, socket() shall return a non-negative
integer, the socket file descriptor."
The test in prepare_fds() however fails if socket fd is
zero (non-negative), which should be a valid value.
This was found while testing the SimpleLink socket offload driver,
which can return a zero-valued socket fd, per the POSIX spec.

This finishes refactor of splitting off net_config library name from
net_app library, started in c60df1311, c89a06dbc. This commit makes
sure that Kconfig options are prefixed with CONFIG_NET_CONFIG_
instead of CONFIG_NET_APP_, and propagates these changes thru the
app configs in the tree.
Also, minor dependency, etc. tweaks are made.

This commit adds TLS support to socket echo_client/echo_server samples.
Credentials used are the same as in the non-socket versions of these
samples, therefore they can be easily tested with net-tools utils.
Maximum payload size for the client was sligtly reduced to fit the
encrypted data within 1280 bytes.
