batman-adv: create netdev->dev_addr assignment helpers

Recent work on converting address list to a tree made it obvious we need an abstraction around writing netdev->dev_addr. Without such abstraction updating the main device address is invisible to the core.

Introduce a number of helpers which for now just wrap memcpy() but in the future can make necessary changes to the address tree.
