2014da4ca3 dhcp4d: display active devices based on LastACK 
This has the advantage that it also works for static DHCP leases,
provided the device obtains a DHCP lease at all (and isn’t configured with a
static IP address, like the shelly motion sensors for example).

593cd8c12d export input/output nftables counters as well as forwarded 
Thus far, we have only had forwarded bytes metrics.

Notably, forwarded bytes does not include bytes that were sent by the router
itself, e.g. by the webserver or rsync server running on the machine.

dhcp4d: ensure that SetHostname operates on the correct lease (#64) 
Previously SetHostname could operate on an expired lease, or even on a
lease for a different hwaddr, if the lease for the correct hwaddr
expired and the same lease ID was given away to someone else.

That's though mostly a theoretical concern, given the actual usage of
SetHostname and the time scales involved.

fa82132962 dhcp4d: add HostnameOverride field 
This can be used to permanently override a hostname, regardless of whether the
lease is static or not. We use a separate field because we want devices to be
able to change their hostname themselves, until we override it.

3dad1e9a23 dhcp4: use the configured (not the current) MAC address 
This fixes a race where dhcp4 started before netconfigd had a chance to change
the hardware address on the uplink0 interface.

fiber7’s port security feature may result in an about hour-long internet outage
without this commit.

bd8fc63b0e dns: implement per-DHCP-lease dyndns 
The HTTP API is easy to use from the command line or from Go:

% curl --data "host=sub&ip=192.168.33.44" -4 http://router7:8053/dyndns
ok
% host sub.$(hostname)
sub.midna has address 192.168.33.44

This can be used in combination with https://github.com/gokrazy/gdns

8c55c5ba44 dhcp4: switch to github.com/rtr7/dhcp4 
All existing DHCPv4 packages I looked at were unappealing for one reason or
another, so we’re now using a little helper to glue github.com/google/gopacket
and github.com/mdlayher/raw together, which suffices for our use-case and gives
us more control.

7d278289f0 captured: directly call NextPacket() to prevent hanging reads 
Using Packets() spawns off a separate goroutine which calls NextPacket in a loop
until io.EOF is returned. This goroutine will stick around after Close()
returned, resulting in only the first wireshark connection working.
