This patch will use atomic operations for sequence number incrementation
while MAC header generation. Upper layers like af_802154 or 6LoWPAN
could call this function in a parallel context while generating 802.15.4
MAC header before queuing into wpan interfaces transmit queue.

Currently there exists two interface types with ARPHRD_IEEE802154. These
are the 802.15.4 interfaces and 802.15.4 6LoWPAN interfaces. This is
more a bug because some userspace applications checks on this value like
wireshark. This occurs that wireshark will always try to parse a lowpan
interface as 802.15.4 frames. With ARPHRD_6LOWPAN wireshark will parse
it as IPv6 frames which is correct.
Much applications checks on this value to readout the EUI64 mac address
which should be the same for ARPHRD_6LOWPAN. BTLE 6LoWPAN and ieee802154
6LoWPAN will share now the same ARPHRD.

6LoWPAN currently doesn't supports x-netns and works only in init_net.
With this patch, we ensure that:
- the wpan interface cannot be moved to another netns;
- the 6lowpan interface cannot be moved to another netns;
- the wpan interface is in the same netns than the 6lowpan interface;
- the 6lowpan interface is in init_net.

Since commit ea81ac2e70 ("ieee802154:
create 6lowpan sub-directory") we have a subdirectory for the ieee802154
6lowpan implementation. This commit also moves the Kconfig entry inside
of net/ieee802154/6lowpan/ and forgot to rename the Makefile entry from
obj-$(CONFIG_IEEE802154_6LOWPAN) to obj-y and handle the
obj-$(CONFIG_IEEE802154_6LOWPAN) inside the created 6lowpan directory.
This will occur that the ieee802154_6lowpan can't be build.

This patch renames the 6lowpan_rtnl.c file to core.c. 6lowpan_rtnl.c
contains functionality to put all 802.15.4 6LoWPAN functionality
together.

This patch moves all relevant transmit functionality into a separate tx.c
file. We can simple separate this functionality like we did it in mac802154.

This patch renames the internal header for af802154. This naming
convention is like ieee802154_i.h in mac802154 and avoids naming
confusing with the global af802154 header. Furthermore this header
contains more ieee802154 specific definitions.

This patch creates an 6lowpan sub-directory inside ieee802154.
Additional we move all ieee802154 6lowpan relevant files into
this sub-directory instead of placing the 6lowpan related files
inside ieee802154.
