interface: POC for multi-dhcp6c support
I'm not entirely sure why we settled for a single deamon of
dhcp6c back in the day, but there are certianly downsides to
it and I don't see something that wasn't fixed in the meantime
that makes this not work.
At the moment this splits off dhcp6c only but we need to
change the daemon's print a bit to avoid complaining about
"other" devices since the situation to ignore a non-listening
interface is normal and not "ignoring" something obvious as
the INFO log message suggests.
rtsold still needs to be split to allow for HUP reload of
a single interface instead of forcing a restart of all
DHCPv6 WAN clients at the same time.
router advertisements: migrate to MVC/API (#9603)
Migrate router advertisements to its own space. Although
the data shifts around a bit the end result should be equivalent.
Of note is that we currently do not have visibility for automatic
interface tracking when not disabled, but they can be disabled
manually by adding the interface configuration and unchecking
the service enable.

radvd: forgot one spot where we wanted to disable automatic tracking
This also means we should not migrate empty nodes that existed because
they were not disabled or DHCPv6 was enabled there once.
radvd: use configtest debug level
In practice this doesn't really matter. I don't see any debug
messages in my installation. Normal logging should go through
and this is also very sparse.
Firewall: Aliases - use new hostdiscovery (with arp/ndp fallback) in mac type aliases.
While here, cleanup some redundant code, if a mac address is in the local cache, the local cache should be complete at anytime.
Technically, for legacy ndp, this might be a bit worse than before, but as hostdiscovery is more complete, that should be a small price to pay.
Eventually, when hostdiscoverty is the standard, we should be able to ditch the /tmp/alias_filter_arp.cache construction as hostdiscovery has its own database.
