Jukka Rissanen 301feea5b4 net: Add struct to store link layer address
Adding a variant for net_linkaddr that can actually store
a link layer address. The normal net_linkaddr struct just
uses pointer to a ll address. The storage version is used
when we have a lladdr cache for neighbors.

Tomasz Bursztyka 4090b4c01f net: Add an L2 layer
Net core then does not know anything about l2 related logic.
For instance ARP is used in ethernet l2 API and nowhere else.
This will be helpful when adding different technologies altogether.

Currently, only SLIP driver is enabled to use relevant l2 layer.

net_core.h is the ground brick of the IP stack, and thus should not
include other headers that might include net_core.h also: this would
create circular dependencies.
