When two domains alias the same name (or one aliases another), display a
meaningful error message like:

    Failed to alias domain 'foo' as 'bar', name already taken by
    domain 'baz'.

The amount of local wifi clients is currently counted by two different
ways:

* asking the kernel wifi layer for the number of of clients on 2.4GHz and
  5GHz band
* asking batman-adv for the number of non-timed out entries in the local
  translation table with WiFi flag

The number of wifi24+wifi5 and the number of TT wifi client counts are
reported via respondd to various consumers. The ffrgb meshviewer is
displaying these values as:

* 2,4 GHz: wifi24
* 5 GHz: wifi5
* other: (TT local wifi+non-wifi clients) - (wifi24 + wifi5)

But the local translation table is holding entries much longer than the
wifi layer. It can therefore easily happen that a wifi client disappears in
the kernel wifi layer and batman-adv still has the entry stored in the
local TT.

The ffrgb meshviewer would then show this count in the category "other".
This often results in confusions because "other" is usually for ethernet
clients. And nodes with a frequently disappearing larger group of clients
(near bus stations or larger intersections) often show most clients under
the group "other" even when this devices doesn't have a LAN ethernet port.

It is better for presentation to calculate the number of total wifi clients
by summing up wifi24 + wifi5. And getting the number of total clients (non
wifi + wifi) by adding the result of the previous calculation to the sum of
non-wifi client in the local batman-adv translation table.

This package allows to automatically switch to another domain, either
at a given point in time or after the node was offline long enough.

This commit distributes dualband radios evenly on 2.4 GHz and 5GHz with
2.4 GHz being prioritised higher than 5 GHz. This means in case a device
has only a single radio and this radio supports operation in both bands,
it will be set to 2.4 GHz.

The original commit only applied its changes to the source file and did
not rebuild the minified file, therefore the change never went live.

The text was changed in the i18n files, but the corresponding change in the
Lua sources seemingly got lost during a rebase.

Closes #1611

(cherry picked from commit 2aa324ec)

Allow odhcp6c to fork the script to handle router
advertisments in 30 seconds intervals. This is the value
that was previously used in Gluon v2018.1 / LEDE 17.01.

The default value is 3 seconds and while it is RFC compliant
it can put alot of pressure on even moderately sized devices.

log-file /dev/stderr is broken for babeld as it eats log messages for debug log.

This reverts commit 104d7455.
in its current form it requires you to enter coordinates, which we don't want to enforce by default.

This patch makes use of the new feature in l3roamd to gracefully
add, remove and list the mesh interfaces that are currently in use. This
helps when changing mesh interfaces often - a characteristic of the
wireguard protocol implementation as in the previous behavior all local
clients are dropped when adjusting mesh interfaces.

gluon-core, gluon-mesh-babel: move lua functions that generate ll-addresses from a mac into gluon-core

gluon-mesh-babel: babel-respond: stop relying on mac addresses and instead obtain ll-address from nic

gluon-wan is a sudo-like exec wrapper that switches the process group to
gluon-mesh-vpn, making it use the WAN dnsmasq rather than resolving over
the mesh.

Note that this only affects DNS at the moment. Processes running under
gluon-wan will still use the regular mesh IPv6 routing table, and not the
WAN routing table. This is not a problem for IPv4, as there is only one
IPv4 routing table.

Fixes #1575

Rename to respondd.c / respondd.so, gluon.mk expects these names. This way
we can remove the install code. The installed filename is changed to
gluon-mesh-babel.so, bringing it in line with out common naming scheme.
