Since we just segmented the IGMP/MLD domain between node and
mesh boundaries, we will not be able to keep track of multicast
listeners on other nodes from the bridge anymore.
Therefore we need to always hand any multicast packets we received from
local clients to batman-adv. We can do this by setting the bridge port
option "multicast_router" to 2.

Filter IGMP/MLD messges so that we can have an IGMP/MLD querier per
node. Segmenting the IGMP/MLD domain on a per node basis allows us
to *not* rely on a central querier (on a gateway for instance) to
take advantage of multicast snooping.
Even though we receive no more reports from other nodes anymore then,
the "multicast_router" bridge port setting will ensure to always
forward multicast packets towards bat0 (unless filtered by another
ebtables rule).
Note that IGMP/MLD are filtered for multicast traffic coming from
the mesh, too (new MULTICAST_IN), as unfortunately there seem to
be other queriers somewhere in the mesh at least for Freifunk
Lübeck. Such queriers would potentially confuse / silence the
querier on a node.

ebtables actually skips any IPv6 extension headers like the hop-by-hop
one. So this rule is actually void.
The intend back then was to allow passing MLD messages into the mesh.
Since extension headers are skipped, the general icmpv6 rule will
actually match MLD messages. So the hop-by-hop rule is unnecessary,
too.

This commit backports fixes from OpenWRT trunk regarding the
multicast-to-unicast feature for the Linux bridge:
* Revert "kernel: disable multicast-to-unicast translation for ipv6 neighbor solicitation (#17625)"
* kernel: bridge, multicast-to-unicast: assign src after pskb_may_pull()
* kernel: bridge, multicast-to-unicast: fix echoes on STA

Convert option ifname in br-client to use a list instead. This
simplifies adding and remove interfaces:
uci:add_to_set("network", "client", "ifname", "eth0")
uci:remove_from_set("network", "client", "ifname", "eth0")
An option ifname will be automatically converted to a list when
performing an upgrade.
Packages affected: gluon-mesh-batman-adv-core, gluon-luci-portconfig
When rebooting the node in config mode, currently the fastd key is
forcefully displayed in a fixed format. This is confusing in communities
where fastd accepts all keys and no key submission is needed.
Furthermore, some communities might want to personalize the display of
the key (see #387).
This patch moves the displaying <div> from the package's lua file to the
translation files of the sample site configuration and mentiones the
change in the release notes.
Apart from replacing a patch for the former by two patches for latter,
this involved minimal adaptations of the lua scripts in the following
packages:
* gluon-announce
* gluon-announced
* gluon-mesh-batman-adv-core
* gluon-status-page
Split basic radio configuration from gluon-mesh-batman-adv as this will
be required for virtually any wireless mesh protocol.
This package takes care of setting:
- wireless channel,
- htmode and
- regulatory domain
gluon-mesh-batman-adv-core depends on this package.
