network: store full hardware address in Link struct
...
This passes the legacy ethernet address to functions in a lot of places,
which all will need migrated to handle arbitrary size hardware addresses
eventually.

network: do not serialize/deserialize addresses
...
The link state file is always removed when networkd is stopping. So,
the deserialization logic does not work. Moreover, the ADDRESSES=
entry is not used by sd-network, so serialization is also not necessary.

network: also unref IPv4 ACD clients in Address objects
...
This should not change any behavior, as currently link_free_engines() is
always called after all addresses are dropped. But the function may be
used in other places in the future. So, let's also stop the clients.

network: directly compare with in_addr element for IPv4 case
...
When peer address is set, address_compare_func() (or address_equal())
does not work in link_is_static_address_configured(), as an Address object
stored in a Link does not contain peer addresses. So, we need to also
compare with in_addr element for IPv4 case.

network: update MAC address in IPv4 ACD clients
...
When the MAC address of a link is updated, an address on the link may
be under checking address duplication. Or, (currently such code is not
implemented yet, but) address duplication check may be restarted later.
For that case, the IPv4 ACD clients must use the new updated MAC address.

Previously, IPv4 DAD is configured in each Address object stored in
Network object. If a .network file matches multipe links, then it causes
an assertion. To prevent it, now IPv4 DAD is configured in each Address
object belogs to Link object.
