b571e45d80 net: if: Extend the usage of rejoining the multicast groups
It may happen that the interface is up but not yet running
when we issue the rejoin_ipv6_mcast_groups(). This can be
fixed by calling this function again right after the iface
is set to 'running' state in the notify_iface_up handler.

d47e0dd93e net: Add IPv6 source address selection support
Add support for IPv6 Source Address Selection defined in RFC 5014.
This commit does not add any address selection support to getaddrinfo()
as described in the RFC. The AI_EXTFLAGS symbol and also the ai_eflags
to hints is added but they are not used by the code.
The public/temporary address selection is only done internally by
the net_if_ipv6_select_src_addr_hint() according to flags set by
setsockopt().

ed9a983837 net: ipv6: Initial support for privacy extension
This creates support for IPv6 privacy extensions which is described
in RFC 8981. This will also add API that can be used to add IPv6
prefixes to a allow or deny list privacy extension filter.

The code will create temporary IPv6 addresses from prefixes that
are advertised by Router Advertisement messages. The temporary
IPv6 addresses are then expired according to lifetime and removed.

In case of successful submission, the reference shouldn't be put down,
this only should done on error cases.

As reference is put down on success, during the buffer unref, no action
is taken due to an uint8 overflow (ref is now 255), so, the buf->frags
isn't cleared properly and the next time the frags is used and when L2
inserts a second frag, the first head frag and next frag are same (due
to buffer re-use) causing an infinite loop in either net_buf_frag_last
or net_pkt_get_len.
