batman-adv: Use packing of 2 for all headers before an ethernet header
All packet headers in front of an ethernet header have to be completely
divisible by 2 but not by 4 to make the payload after the ethernet header again
4 bytes boundary aligned.
A packing of 2 is necessary to avoid extra padding at the end of the struct
caused by a structure member which is larger than two bytes. Otherwise the
structure would not fulfill the previously mentioned rule to avoid the
misalignment of the payload after the ethernet header. It may also lead to
leakage of information when the padding it not initialized before sending.

batman-adv: Fix broadcast duplist for fragmentation
If the skb is fragmented, the checksum must be computed on the
individual fragments, just using skb->data may fail on fragmented
data. Instead of doing linearizing the packet, use the new
batadv_crc32 to do that more efficiently- it should not hurt
replacing the old crc16 by the new crc32.

batman-adv: support array of debugfs general attributes
This patch adds support for an array of debugfs general (not soft_iface
specific) attributes. With this change it will be possible to add more general
attributes by simply appending them to the array without touching the rest of
the code.

The following commit has been merged in the master branch:
commit bb351ba0bba23f01af00e36bfe20897201f404fa

batman-adv: Add wrapper to look up neighbor and send skb
By adding batadv_send_skb_to_orig() in send.c, we can remove duplicate
code that looks up the next hop and then calls batadv_send_skb_packet().
Furthermore, this prepares the upcoming new implementation of
fragmentation, which requires the next hop to route packets.
Please note that this doesn't entirely remove the next-hop lookup in
routing.c and unicast.c, since it is used by the current fragmentation
code.
Also note that the next-hop info is removed from debug messages in
translation-table.c, since it is looked up elsewhere.
