Hi,

As part of the effort to allow the compiler to reason about object sizes,
we need to deal with the problematic variably sized struct sockaddr,
which has no internal runtime size tracking. In much of the network
stack the use of struct sockaddr_storage has been adopted. Continue the
transition toward this for more of the internal APIs. Specifically:

- inet_addr_is_any()
- netif_set_mac_address()
- dev_set_mac_address()

Only 3 callers of dev_set_mac_address() needed adjustment; all others
were already using struct sockaddr_storage internally.
