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.)
