util-lib: add ether_addr_from_string()
This isn't quite symmetrical to in_addr_from_string() because it also returns an offset indicating how much of the string was consumed by the matched pattern. This offset reporting is needed for either of the following use cases: * verifying the lack of trailing garbage after such an address * parsing subsequent data from the same string
