The proto_ops::getname callback was long ago backed by sockaddr_storage,
but the replacement of it for sockaddr was never done. Plumb
sockaddr_storage through all the getname callbacks and adjust prototypes
and needed casts. Mostly casts to sockaddr are removed, though to avoid
spilling this change into BPF, cast the sockaddr_storage instances to
sockaddr for the time being.
