Add support for IP_LOCAL_PORT_RANGE socket option. The option
supports both IPv4 and IPv6 sockets although the type is IPPROTO_IP.
The option can be used to enforce the ephemeral port number selection
to be in certain range.

This is helper is only needed in socket multicast interface selection
where we need to get one address from the interface so that it will
tell (when getsockopt() is used), the interface IPv4 address where
multicast packets will be sent. This is private function which is not

Print information in "net ipv6" command how the SLAAC addresses

Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no>
This implements support for RFC 7217 which describes a method
to have stable IPv6 Interface Identifiers to be used with IPv6
Stateless Address Autoconfiguration (SLAAC). The stable IIDs are used
to provide enhanced privacy so that an IPv6 address configured using
this method is stable within each subnet, but the corresponding
Interface Identifier changes when the host moves from one network
to another. This method is meant to be an alternative to generating
Interface Identifiers based on hardware (MAC) addresses,
such that the benefits of stable addresses can be achieved without
sacrificing the security and privacy of users.

If network interface is specified in the DNS server, then send

information in the server list.
Signed-off-by: Jukka Rissanen <jukka.rissanen@nordicsemi.no>
Allow user to specify a network interface in the DNS server
list. User can append "%" and network interface name to the
DNS server to use this. If the network interface is mentioned
in the server list, then the DNS queries are sent via this network
interface.
For example setting the interfaces like this:
192.0.2.2%eth1
[2001:db8::2]:5353%ppp0
would cause the DNS queries to sent to 192.0.2.1 via eth1 in the first
example, and to 2001:db8::2 via ppp0 in the second example.

If trying to parse a string like 192.0.2.2:80/foobar and
setting the length to 12 which means to parse the IP address

was terminated after the port number.

When response is received and handled, don't just clear the structure
but instead mark it as ongoing=false.
So if we later on receive a duplicate response for it, we can still
respond with Ack or Rst.
This is achieved by using release_internal_request() when we don't
expect any response for it and reset_internal_request() when we really
fill up a new request.
