When using NATs and tunnels at the same time, the correct
source address has to be used so the ICMP errors is sent
through the NAT. This is necessary so the NAT can modify
the ICMP payload so it is correctly identified by the
destination host, which is required for PMTUD

mtr can be a very helpful tool when debugging unstable
networks. The tool is able to list packet loss to all
routers to a destination in a nice console-based interface.

So far, we have meta packages and config packages for the variants
in parallel, e.g. fff-node and fff-variant-node.
Since the sole purpose of the meta packages is to define
dependencies, one can just merge them into the corresponding config
packages to reduce overhead.

In some cases (mostly for one-port devices) IF_WAN was used
although not set, resulting in not obviously iptables error
messages like
- Bad argument `conntrack'
- Bad argument `REJECT'
Thus, check whether IF_WAN is set to something before using it.

When running OpenWrt master, "type <functionname>" only returns
"<functionname> is a function". Thus, to make the implementation
future-proof and since it is also working with the current state,
change the grep in execute_subshell to match "function".

This adds scripts to configure vlan and client network.
This also adds sysctl settings to enable forwarding.
Note:
Devices specific properties are sourced from fff-network package.
This creates a dependency on fff-boardname and fff-network.
These properties should be located elsewhere in the future.

This introduces a new script for simple gateway configuration.
The main configuregateway script is able to execute functions
for various steps like 'configure' or 'apply' from scripts in /etc/gateway.d.
This makes it easy to distribute configuration to the appropriate packages.
