Fixes #800

The mesh side has become fairly huge in many communities. Up to
a few thousand entries can currently be found in the forwarding
database (fdb) of a bridge for its bridge port bat0.

The bridge fdb is kind of redundant to the batman-adv global translation
table here. Therefore this patch tries to reduce memory footprint by
following an approach similar to the IGMP/MLD split patchset approach:

Make the bridge oblivious not only regarding multicast listeners towards
the mesh but with this patch unicast hosts on the mesh, too.

If the destination of an ethernet frame is known by the bridge to be a
local one, then the frame is forwarded to the according port. If it is
unknown, then the frame is forwarded to the wifi AP interface and bat0.

mac80211 and batman-adv then know whether to drop or forward a frame
further through their own book-keeping.

Note that unicast-flood is not disabled for the wifi AP bridge port, nor
is learning disabled on the wifi AP. This is mainly to keep the
configuration in UCI and according setup scripts simple ;). However, not
disalbling unicast-flood on the wifi AP interface might also give a
minor latency improvement for newly joining wifi clients.

Includes a few security updates and enables Curve25519 support.

Fixes #223

This patchset enables the RX LNA for the CPE210/510, improving RX by about
20dB. The profiles for CPE210 and CPE510 is split into two images.

The problematic patch switching the CPE510 to the secondary ART is left
out.

I've bought a couple of those devices from Senetic GmbH.

They have 16 MB of Flash and 64 MB of RAM. Platform support works fine,
I've also tested a little with Ethernet (since I saw some regressions on
OpenWRT/LEDE with 841v11), no problems.

Therefore, lets remove the broken mark.

Switching branches and applying patches in the build repos will
unnecessarily touch many files, causing rebuilds of packages that didn't
really change; furthermore, it is filling the reflog with many entries.

Don't ever switch to base branch in the build repos and apply patches in
a temporary clone to avoid these issues.

In addition, GPG signing is generally disabled in the build repos to
override potential global configuration (as signing doesn't make sense and
will slow down rebases).

Fixes #845

The main advantage is that procd is capable of logging stderr to logd,
making errors easier to debug.

Fixes #328

Add Buffalo WZR-HP-G300NH2 to Makefile, device is already supported in OpenWrt and LEDE.
Verified functionality with actual device.

Fixes #658

Filter IGMP+MLD

Caused by a broken backport.

Fixes #689

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

Fixes autoupdater for Hotnet-UB and AP121. Also add note about broken
autoupdates on Tube2H.

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

[Matthias Schiffer: removed PROVIDES dependency]

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.
