Use the common term; the "Expert Mode" never was a distinct mode of
operation anyways.

The arguments are now provided by gluon-mesh-batman-adv-core, so
gluon-radvd can be used with other mesh protocols.

gluon-neighbour-info: improve verbosity on wrong cli parameters

Some drivers (mt76) don't support arbitrary MAC addresses. Use the
addresses provided by the driver (avoiding the primary address) by default,
but fall back to our has-based scheme when the driver doesn't provide
(enough) addresses.

Accidentially forgot to commit this. The sleep is necessary so netifd can
actually stop the WLAN interfaces after `wifi down`.

Most doubles that are delivered via respondd have limited input
precision, but are converted with up to 17 digits of precision. That can
cause ugly blowups like 0.2800000000000001 in the output, which is
avoided by specifying better format strings (like "%.2f" in most cases).

The OpenMesh devices have a sticker with the eth0 mac address on the
bottom. Also all other mac addresses are calculated based on this address.
Therefore, it is better to use this as primary mac address instead of the
WiFi mac address.

This patch adds a new gluon-ebtables package to filter IGMP/MLD messages
via ebtables.

For one thing this reduces multicast overhead: About one third of all
ICMPv6 multicast traffic in Lübeck or Hamburg is MLD.

Furthermore it removes a potential Distributed Denial-of-Service vector
(see Gluon ticket #553).

Finally, it is a prerequisite for enabling bridge multicast snooping in
a decentral and robust fashion.

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. Also adding these rules to be prepared to anyone intentionally
or unintentionally disabling these filters on his/her node.

Node operators not running Gluon (for instance gateway nodes) should
make sure to either enable multicast_router towards bat0 or disable
multicast snooping entirely if they have a bridge on top of bat0.

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.

Replace debug.setfenv hack to close stdout with nixio.dup.

This was causing "recursive dependency" errors and potentially broken
configurations.

The image validation currently fails on some devices (tested OpenMesh)
because it isn't done via sysupgrade. But the checks depend partially on
the integration in sysupgrade (e.g. via loops that can be stopped via
"break statements").

Instead of hacking its own version check, it is easier and better tested to
just use 'sysupgrade -T' like it is already done by LuCI.

Fixes #764

Also backport some patches improving QCA956x support.

Lua's tables are 1-based, so we must decrement the index by 1 to get the
desired MAC addresses. By not doing this, the second IBSS interface would
get the address with index 8, but only indices 0..7 are available.

There are a few devices which have more than one LAN interface (for example
some revision of the TL-WR941ND, which uses a DSA-based switch, so each
switch port has its own netdev.) On these devices we need a bridge for
mesh-on-lan (as the alternative of adding them to batman-adv individually
would need too many MAC addresses.)

While ath9k/ath10k devices can supprt VIFs with any combination of MAC addresses, there are also adapters which have a hardware MAC filter which only allows a few bits to differ. This commit changes the addresses of all VIFs to ony differ in the last 3 bits, which is required to support many Ralink/Mediatek based WLAN adapters.

Technically, the new addresses are generated by calculating an MD5 hash of the primary MAC address and using a part of this hash as a prefix for the MAC addresses.

The addresses (BSSIDs) of the AP VIFs are also reused for the LAN and WAN interfaces in mesh-on-LAN/WAN mode to reduce the number of needed addresses, and thus reduce the chance of collisions. This is not a problem as the MAC addresses of the AP VIFs are never used except as BSSID, and thus not seen by routing protocols like batman-adv.
