When we are about to send a NS, we should not use the destination
address as that is typically the multicast address. We should use
the target address instead.
This fixes the case where a neighbor is in incomplete state, and
we send a neighbor solicitation to find out whether the neighbor
is reachable. In this case the destination address is the solicited
node multicast address which is no use when trying to figure out
the source address.

This commit fixes a problem where our own IP address
is added to the cache instead of the senders.
This bug was due to a swap of the address in the original packet.
The swapping of the address is now removed.

A neighbor solicitation packet for an address that is not ours should
not cause the sender to be added to the neighbor cache. See RFC 4861
section 7.2.3.
Add the neighbor to the cache when we have decided to respond to the
NS packet.
Fixes#21869.

Use the same code when parsing source link-layer address option for
both RA and NS packets. It looked like handle_ns_neighbor() could
actually read too much data into lladdr.addr when handling 8-byte
addresses (802.15.4).

A memory corruption could happen in `uncompress_IPHC_header` function,
when data was moved to make place in the net buffer for the uncompressed
IPv6/UDP header.
The size of data being moved should only contain the original data size,
not incremented by the amount of space needed to expand the header,
which was already added to the net buffer size. In result, the `memmove`
operation could exceed the allocated net buffer and cause memory
corruption.

If no other route is found, the network interface prefixes are
evaluated. If a matching interface is found, the packet is sent out on
this interface.

The address family of the received packet must be set, before routing
it. E.g. the ethernet driver would drop the packet if this is not
done.

The commit 8892406c1d ("kernel/sys_clock.h: Deprecate and convert
uses of old conversions") changed code to not use deprecated macro.
Unfortunately there was some changes done to RX TC stats update that
were missing from that commit. This commit fixes the issue and removes
the last user of the deprecated SYS_CLOCK_HW_CYCLES_TO_NS64() macro.
This is follow up to commit 5bbdf56769 ("net: stats: Fix RX time

macro.

An expired IPv6 router would cause an infinite loop where
iface_router_run_timer() repeatedly scheduled a work item. In some
conditions it would schedule with negative delay, in other conditions
the infinite loop wouldn't happen until a router was added again.
Get rid of the router from active_router_timers when it is removed.

Remove leading/trailing blank lines in .c, .h, .py, .rst, .yml, and
.yaml files.
Will avoid failures with the new CI test in
https://github.com/zephyrproject-rtos/ci-tools/pull/112, though it only
checks changed files.
