On layer3 variant ("gateway firmware"), 60-fff-gateway.conf
changes "forwarding" for all interfaces, overwriting the
changes from 51-fff-network-$iface.conf.

By putting the WAN-specific commands after 60-fff-gateway.conf
this patch should provide the correct device-specific value
for WAN interface now.

In d9ec8edb ("batman-adv: Move from DEBUGFS to batctl") we
switched from deprecated DEBUGFS to batctl.

Despite debugfs, batctl seems to also have deprecated sysfs
(https://www.open-mesh.org/news/90

).

This patch thus replaces a reference to iface_status by the
corresponding batctl command.

"ip" is one of the most essential tools on a gateway. At the moment
there is only one dependency to the metapackage ip from the nodewatcher,
which pulls ip-tiny. Dropping the nodewatcher causes a fallback to the
busybox built-in ip-command.

This package adds gateway.d scripts which create

When the user removes a peer from /etc/config/gateway,
the script has to be able to find any leftover configurations
that have been created for it.

This can be made very easy by prepending a prefix to every
automatically generated configuration.

This also allows to remove the nasty check for the babeld default interface.
Therefore the naming check for cfg* also can be removed.

As a side effect all manually created configuration blocks that do not match a
prefix will not be touched by configuregateway.

Previously, when configurehood switched status, all WiFi devices
were completely rewritten and all interfaces were deleted and
recreated. This is both unnecessary and ugly.

This patch redesigns WiFi setup to create all interfaces (in
parallel) initially, and then only to enable/disable them as
necessary. Where reconfiguration is necessary, only the variable
parts are changed.

Since most of the wifi-device config is already created by
OpenWrt, this builds based on the existing wifi-devices and
only removes the default wifi-ifaces.

This patch will not change the logic (codeflow) of configurehood,
but only affects how action on the WiFi devices/interfaces is
taken.
