We should change the skb->dev pointer earlier to the lowpan interface
Sometimes we call iphc_decompress which also use some netdev printout
functionality. This patch will change that the correct interface will be
displayed in this case, which should be the lowpan interface.

This patch moves some trivial checks at first before calling
skb_share_check which could do some memcpy if the buffer is shared.

This patch cleanups the pull of the iphc bytes. We don't need to check
if the skb->len contains two bytes, this will be checked by
lowpan_fetch_skb_u8.

We don't need to check if the wpan interface is running because the
lowpan_rcv is the packet layer receive handler for the wpan interface.
Instead doing a check if wpan interface is running we should check if
the lowpan interface is running before starting 6lowpan adaptation layer.

Inside the IEEE 802.15.4 6LoWPAN subsystem we use two interfaces which
are wpan and lowpan interfaces. Instead of using always the variable
name "dev" for both we rename the "dev" variable to wdev which means the
wpan net_device and ldev which means a lowpan net_device. This avoids
confusing and always looking back to see which net_device is meant by
the variable name "dev".

We receive all 802.15.4 frames on the packet handler "lowpan_rcv" this
patch checks if the wpan device belongs to a lowpan interface.

We currently supports multiple lowpan interfaces per wpan interface. I
never saw any use case into such functionality. We drop this feature now
because it's much easier do deal with address changes inside the under
laying wpan interface.
This patch removes the multiple lowpan interface and adds a lowpan_dev
netdev pointer into the wpan_dev, if this pointer isn't null the wpan
interface belongs to the assigned lowpan interface.

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