If the interface is WiFi one, then print information about it.
Also the device information is useful to know so print device
name corresponding to the network interface.

If user adds IPv6 address to the network interface, check
if the address is a multicast one and add it to multicast
group if it is.

The new "net sockets" command will utilize the object core
support to track and show information about BSD sockets that
are created in the system. This command is able to show info
for all network sockets (native, offloaded etc) in the system.
Example of the output of the new command:
uart:~$ net sockets
Creator Name Flags FD Lifetime (ms) Sent Received
main af_inet46 6ST 0 3260 819 498
main af_inet46 4ST 1 2110 469 142
main af_inet46 6DU 2 2110 9941 9941
main af_inet46 4DU 3 2110 1375 621
4 active sockets found.

In case ping is sent to own address, the request is looped back to the
stack and served before ping work had a chance to reschedule. In result,
when the final ping reply has been server, and ping operation finalized
with `ping_done()`, the work was rescheduled one last time, causing the
ping timeout to be reported. Fix this by rescheduling the work before
sending the actual request, so that the reply handler can cancel the
work properly in such case.

The remote address of the connection is checked whether
it is v4-mapping-to-v6 address in which case we should
print it such.

Fix two issues with net tcp command:
* The `net tcp` commands are still based on net_context API. For TCP,
the API caller (net shell) should add one extra reference to the
allocated net context, to prevent premature context release in case of
connection teardown. Currently that was not the case, and the context
was released too early, resulting in missing final ACK from the Zephyr
side on connection close.
* The net context API should not be called from the registered connect
callback, as this creates a temporary deadlock situation. The
net_context_connect() function blocks until the connection is
established, or an error or timeout occurs. For that time the
net_context mutex is being locked. In case of connection error (for
example after receiving RST packet) the connect callback is called,
indicating an error. If we try to call net_context API from within, a
deadlock situation takes place, as the context mutex is still locked
by the net_context_connect() (called from the shell thread). This
blocks the further execution of the TCP stack and can result in an
unexpected behavior (like for example retransmitting the SYN packet,
which takes place from yet another thread, TCP work queue).
Fix this, by releasing the net context not from the callback directly,
but based on the return value from net_context_connect().

Allow multiple commands use the same dynamic shell command
completion when expecting network interface index.
For example "net iface" and "net stats" are such commands.
The network interface expansion cannot be used in "net ipv6 add",
"net ipv4 add" and "net route" commands as they require more
data after the network interface index argument.

The "net stacks" has been obsolete for a long time already
so remove it for good. It is replaced by "kernel stacks" cmd.

This is a preparation for the refactoring. The old "net" command
is renamed "net_old" so that the individual commands can be
placed into a separate .c files.
This is done like this because we need to use the
SHELL_SUBCMD_SET_CREATE() to create the sub-command and then
use the SHELL_SUBCMD_ADD() in the .c files to add the command
into the sub-command and not get conflict with the same name
sub-command.

This is preparation commit that moves the net shell code to
subsys/net/lib/shell directory. The following commits will
then refactor the code in net_shell.c to smaller and more
manageable pieces.
