Use CAKE for shaping ingress as well as egress bandwidth shaping.

CAKE allows to better shape egress as well as ingress bandwidth. It not
only performs bandwidth shaping but also flow-queueing.

This in conjunction with the batadv flow dissector allows us to utilize
CAKE for all mesh-implementations currently supported in Gluon.

Add GLuon meta-package to include on devices that support SQM.

This package provides sqm-scripts as a dependency. SUpporting mesh-vpn
protocols can then conditionally enable SQM on the VPN link.

This code was added way back in 2017. We don't support updates from
those old versions, so we can remove it.

In case no interface role was selected for a given interface,
gluon-reconfigure currently fails with

Allocation of the router structure for newly detected router
advertisements was done using malloc and selectively clearing some of
the structure fields. However the redirect boolean was never set to 0,
which means that during update_redirect, we would depend on the random
initialization value of the structure.

This means that sometimes ebtables-tiny wouldn't add the correct rules
for the advertised routes.

Enterasys WS-AP3715i is a dualband wireless-N access point.
It comes in a similar casing as the WS-AP3825i, however the hardware is
fundamentally different from its bigger cousin.

Rewrite the gluon-wan-dnsmasq initfile to use procd. This allows for
configuring restart handling by procd in case of a crash.

While at it, disable the caching feature optionally used for the regular
dnsmasq on the wan dnsmasq. This daemon is only for redirecting DNS
requests to use local network resolvers, not introducing caching.

The tunneldigger init script has been migrated to procd, so there is no
PID file anymore. Remove the obsolete check altogether - it shouldn't
be needed anymore, as procd will take care of crashes of tunneldigger by
itself. This fixes the watchdog resetting tunneldigger every time it runs.

Use DNS servers received from the cellular provider for the WAN dnsmasq

This reverts commit 97efc8ab. (#2580)

Since the commit was openend the device was moved from ath79-generic to ath79-tiny ([4b5bd15](https://github.com/openwrt/openwrt/commit/4b5bd1509195bc8f19999ebe481b59356b5c3512)).

Therefore the commit breaks builds of the ath79-generic target (`unable to enable device 'ubnt_rocket-m'`).

It might be possible to add support for the ath79-tiny target, and with it the Rocket M2/M5 (XM), in the future.
