Would be nice to avoid a bunch of the overly long lines, but the
fundamental changes looks good:

The proto_ops::getname callback was long ago backed by sockaddr_storage, but the replacement of it for sockaddr was never done. Plumb it through all the getname() callbacks, adjust prototypes, and fix casts. There are a few cases where the backing object is _not_ a sockaddr_storage and converting it looks painful. In those cases, they use a cast to struct sockaddr_storage. They appear well bounds-checked, so the risk is no worse that we have currently. Other casts to sockaddr are removed, though to avoid spilling this change into BPF (which becomes a much larger set of changes), cast the sockaddr_storage instances there to sockaddr for the time being. In theory this could be split up into per-caller patches that add more casts that all later get removed, but it seemed like there are few enough callers that it seems feasible to do this in a single patch. Most conversions are mechanical, so review should be fairly easy. (Famous last words.)
