Show detailed information about network interface that is down,
only when user asks such information about one specific network
interface. This means that for "net iface" command only
"Interface is down." is printed but the command "net iface 1"
will print detailed information even if interface is down.
This helps to view the information and user does not need
to bring interface up to see the details.

Add infrastructure to allow user to configure the system so that
all the network packets, that are sent to or received from a specific
network interface, are sent to remote system for analysis.
The captured network packets are placed as a payload in UDP packet,
which is then sent inside a tunnel to a remote host. The host can
then receive the packets and for example show them in wireshark.

Implement SO_BINDTODEVICE socket option which allows to bind an open
socket to a particular network interface. Once bound, the socket will
only send and receive packets through that interface.
For the TX path, simply avoid overwriting the interface pointer by
net_context_bind() in case it's already bound to an interface with an
option. For the RX path, drop the packet in case the connection handler
detects that the net_context associated with that connection is bound to
a different interface that the packet origin interface.

Introducing PPP dialup features to enable e.g. usage of nrf9160
based board as a dialup modem for transferring ip data over PPP
(e.g. windows dial up), i.e. usage of Zephyr PPP as a server for
providing MTU/MRU, IP address and DNS addresses for a PC:
- PPP LCP MRU option (configurable)
- PPP server: IPCP ip and dns address peer options to enable
providing IP and DNS addresses for PPP peer.

The specification states that the server can cancel observations "at any
moment, by sendinga GET request with Observe option=1, the LwM2M Server
cancancel an “Observe”operation on a specified Resource, or specified
Object Instance(s)."
It does not mention any token matching requirement, but RFC 7641 does.
The correct interpretation is not obvious. The EMQx LwM2M implementation
uses a new token for instance, which does not work with Zephyrs token
matching cancel-observe.
This commit introduces cancel-observe via path matching as a Kconfig
option. This could hypothetically introduce problems when we are
connected to multiple peers simultaneously, but since that is not likely
to be supported for a long time (if ever), this change should be fairly
uncontroversial since path matching is only used as a fallback.

Current implementation of poll prepare/update could end up busy looping
if `poll()` function was called before/during DTLS client handshake
(i. e. `poll()` called before an initial `send()`).
Fix this, by monitoring the handshake semaphore, already available in
the tls_context structure for DTLS client instead of underlying socket.
After the handshake is complete, switch to monitoring the underlying
socket instead.
For DTLS server this is not needed, since the handshake is initiated in
the `recv()` function, therefore any incoming data should trigger the
handshake.

IPv6 source address selection procedure selected link-local address
for any muticast destination with other scope than mesh-local. It
was a cause of problems for broader multicast scopes like admin-, or
site-local. For such broader scopes source address must be at least
as broad as the scope of multicast destination.
This patch updates IPv6 source address selection procedure. Now
link-local address is selected only for link-local destinations,
including multicast destinations. For broader destination scope,
source address with broader scope is selected.

net_eth_carrier_on() and net_eth_carrier_off() call k_work_init() on
work item that can be pending or still be processed in another thread.
This results in undefined behavior.
Initialize work item once and use an atomic flag to switch between
up/down carrier state. Submit work to workqueue whenever up/down carrier
state changes, so that last state is always properly propagated to
network interface layer.
While at it, save network interface pointer during ethernet context
initialization, so that is becomes static (and thread-safe) during whole
ethernet context lifetime.
