Add the following option to the client config section in
/etc/config/gateway to enable a basic stateful firewall:

config client
    option stateful_firewall '1'

The firewall will forward icmp mesages and allow any outbound client
traffic and related inbound traffic.

Add the following option to the client config section in `/etc/config/gateway` to enable a basic stateful firewall: ``` config client option stateful_firewall '1' ``` The firewall will forward icmp mesages and allow any outbound client traffic and related inbound traffic.

8be918ad49 WIP: fff-firewall: Switch from ip/ebtables to nftables

Include nftables and appropriate modules. Translate ip- and ebtables
rules to their nftables counterparts. Remove ip/ebtables and modules.

This change intentionally tries to keep structural changes at a minimum
to keep the rule translation comprehensible.

kmod-nft-bridge is not required for fff-node, because it was merged into
a single kernel module since Linux 4.17:

Fixes: #252
