A few issues with the bridge snooping were identified and fixed
upstream in OpenWRT:
* "firewall: Allow IGMP and MLD input on WAN" (r45613)
* "kernel: bridge: backport two snooping related patches" (r45783)
* netifd: "bridge: Fix multicast_to_unicast feature by hairpin+isolate"
(OW: "netifd: update to the latest version, adds multicast-to-unicast fixes" (r46719))
* "kernel: bridge, multicast-to-unicast: assign src after pskb_may_pull()" (r46721)
* "kernel: bridge, multicast-to-unicast: fix echoes on STA" (46765)
These have very likely caused issues with the bridge snooping before,
which led to disabling it in the past. Let's reenable the multicast
snooping now that they were fixed for reduced multicast overhead on the
wifi.
Advantages are the following:
This mildly reduces overhead on the mesh layer. And significantly reduces
overhead on the AP interface and therefore significantly increases
available airtime (the currently most significant scalability bottleneck).
Secondly removes an easy, often accidental node-local Denial-of-Service
vector based on multicast flooding / streaming.
Thirdly, makes node-local multicast streaming feasible.
Finally should noticably increase battery life of mobile devices.
Note: bridge querier is disabled for br-wan. We want to avoid becoming
too "bossy"/"noisy" on a foreign network.

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]
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.
This call takes an input and an output argument and will copy all files
from the input to the output, while minifying the Lua files.
[Matthias Schiffer: simplified definition, added commit message.]
Introduce new fixes:
* Avoid nullptr dereference in bla after vlan_insert_tag
* Avoid nullptr dereference in dat after vlan_insert_tag
* Avoid tt_req_node list put for unhashed entry
* Fix orig_node_vlan leak on orig_node_release
* Fix non-atomic bla_claim::backbone_gw access
* Fix reference leak in batadv_find_router
* Free last_bonding_candidate on release of orig_node
Also replace the gluon version of the speedyjoin patch with the one already
included in openwrt-routing.
