The batadv_vlan proto doesn't need to do anything when it gets teared down.
But the scripts are still trying to call the teardown function of this
proto. This results in warnings like:
daemon.notice netifd: batmesh1 (18940): ./batadv_vlan.sh: eval: line 37: proto_batadv_vlan_teardown: not found
Just providing a stub function avoids this log spam.

- Hold rtnl lock during MTU update via netlink
Signed-off-by: Sven Eckelmann <sven@narfation.org>
The automatic recalculation of the maximum allowed MTU is usually triggered
by code sections which are already rtnl lock protected by callers outside
of batman-adv. But when the fragmentation setting is changed via
batman-adv's own batadv genl family, then the rtnl lock is not yet taken.
But dev_set_mtu requires that the caller holds the rtnl lock because it
uses netdevice notifiers. And this code will then fail the check for this
lock:
RTNL: assertion failed at net/core/dev.c (1953)

Commit 97d35a552ec5b6ddf7923dd2f9a8eb973526acea of musl introduced the
macros __LITTLE_ENDIAN and __BIG_ENDIAN in alltypes.h. These are pulled
into the compilation of batman-adv. This has the side effect that the
function is_multicast_ether_addr of etherdevice.h in Linux kernel is
compiled as the big endian version and so fails to work properly on
little endian devices.
This commits prevents pulling in header files of musl libc similar to

This changes the package version string so it does not start
with "openwrt", but with the base version we are modifying:
So far: openwrt-2019.4-1
Now: 2019.4-openwrt-1
Since it's us modifying version 2019.4 (in this case), this order
is more convenient (and also closer to what the kernel version
string does).

replaced with device type specific subcommand prefixes:

The state of slave interfaces are handled differently depending on whether
the interface is up or not. All active interfaces (IFF_UP) will transmit
OGMs. But for B.A.T.M.A.N. IV, also non-active interfaces are scheduling
(low TTL) OGMs on active interfaces. The code which setups and schedules
the OGMs must therefore already be called when the interfaces gets added as
slave interface and the transmit function must then check whether it has to
send out the OGM or not on the specific slave interface.
But v2016.3 moved the setup code from the enable function to the activate
function. The latter is called either when the added slave was already up
when batadv_hardif_enable_interface processed the new interface or when a
NETDEV_UP event was received for this slave interfac. As result, each
NETDEV_UP would schedule a new OGM worker for the interface and thus OGMs
would be send a lot more than expected.
