This will add support to skip bytes from skb with the lowpan_fetch_skb
function.
This is necessary for upcomming patches.

The current fragmentation implementation isn't rfc4944 compatible so a ping
with a
payload of > 127 with other 6lowpan implementations like contiki isn't possible.
This patch fixes the fragmentation implementation to rfc4944 so fragmentation
with
ping comes possible,
Also fix some race conditio
This patch indentation fixes are necessary for the upcomming patches.
It removes some whitespace issues which checkpatch pointed out.

This is necessary for upcomming patches to calculate the 6lowpan header.
It's a little bit tricky here because a UDP transport header can be
compressed in the network header, so the UDP header is merged in the
6lowpan header. In this case the transport header points to the payload
of the UDP header

The current implementation does many copies of the sk_buff for
increasing headroom which are not necessary.
This patch increases the headroom in the maclayer for a worst case
scenario of (sizeof(struct ipv6hdr) + sizeof(struct udphdr)).

function delivers the skb to ipv6 handler and the ipv6 handler will set
these headers.
