This updates the batman-adv OpenWrt package to the current version
provided in the master branch of the openwrt-routing packages
repository:
* e26096a batman-adv: Fix duplicated OGMs on NETDEV_UP
* 1ff00ee batman-adv: upgrade package to latest release 2019.2
Small difference to the original:
* Compat code for batadv_genl_dump_check_consistent()
* Compat code for cfg80211_sinfo_release_content()
* 0001-batman-adv-add-compat-hacks.patch kept
* batctl dependency kept removed
* config related files unchanged
The new config format was not backported yet to keep this patch small
and less invasive.

This always pulls in the batman-adv compat 15 kernel module. However,
batctl works just as well with batman-adv-legacy (compat 14).

A reference to the best gateway is taken when the list of gateways in the
mesh is sent via netlink. This is necessary to check whether the currently
dumped entry is the currently selected gateway or not. This information is
then transferred as flag BATADV_ATTR_FLAG_BEST.
After the comparison of the current entry is done,
batadv_*_gw_dump_entry() has to decrease the reference counter again.
Otherwise the reference will be held and thus prevents a proper shutdown of
the batman-adv interfaces (and some of the interfaces enslaved in it).

The first one adds a fix that might potentially result in multicast packet
loss once we would enable multicast_mode again.
The second one avoids some small but unnecessary overhead. More
importantly though, it is supposed to ease further multicast improvements
later (e.g. no need for a multicast sending node to determine overlap
between WANT_ALL_IPV4/6 flags and TT entries while on fast-path).

Also remove our own no_rebroadcast patch, as batman-adv v2016.5 now has a
more sophisticated rebroadcast suppression that should work automatically
in the most relevant cases.
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.

Speedy join only works when the received packet is either broadcast or an
4addr unicast packet. Thus packets converted from broadcast to unicast via
the gateway handling code have to be converted to 4addr packets to allow
the receiving gateway server to add the sender address as temporary entry
to the translation table.
Not doing it will make the batman-adv gateway server drop the DHCP response
in many situations because it doesn't yet have the TT entry for the
destination of the DHCP response.
