Eric Dumazet changed the mc_forwarding in commit 145c7a793838 ("ipv6: make
mc_forwarding atomic") the type of mc_forwarding from __s32 to an atomic_t.
This patch was then ported to various stable kernels.
This code change caused a FTBFS when in batman-adv when
CONFIG_BATMAN_ADV_MCAST was activated. To work around this problem, provide
a version for kernels with __s32 mc_forwarding and a version for kernel
with atomic_t mc_forwarding.

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
OpenWRT commit 9ac47ee46918c45b91f4e4d1fa76b1e26b9d57fe

The batman-adv netlink messages often contain the interface index and
interface name in the same message. This makes it easy for the receiver to
operate on the incoming data when it either needs to print something or
needs to operate on the interface index.
But one of the attributes was missing for:
* neighbor table dumps
* originator table dumps
* gateway list dumps
* query of hardif information
* query of vid information
The userspace therefore had to implement special workarounds using
SIOCGIFNAME or SIOCGIFINDEX depending on what was actually provided.
Providing both information simplifies the userspace code massively without
adding a lot of extra overhead in the kernel portion.

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).

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.
