netconfig: implement WireGuard support
...
To set up a tunnel, create a /perm/wireguard.json as illustrated in
netconfig_test.go, and don’t forget to adjust your /perm/interfaces.json with
the address configuration for the WireGuard tunnel.
Note that static routes cannot currently be configured, so the usefulness is
limited. If you have a use-case you’d like to see covered, please explain it in
https://github.com/rtr7/router7/issues/14

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.

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.

implement TCP MSS clamping (for non-ethernet uplinks)
...
We didn’t have a need to clamp the TCP Maximum Segment Size (MSS) up until now,
because fiber7 uses an MTU of 1500.
Because Path MTU discovery is often broken on the internet, it’s best practice
to limit the Maximum Segment Size (MSS) of each TCP connection, achieving the
same effect (but only for TCP connections).
This change is beneficial when running router7 behind a non-ethernet uplink,
such as a Fritz!Box cable modem.
This has no adverse effect on fiber7: after clamping, the MSS is still 1440, as
without clamping.
