strncpy is generally deprecated; any remaining uses you find of it
are probably only there for lack of round tuits. Use strlcpy in new
code, unless there's a pretty strong argument that strncpy is actually
clearer for a given usage.
(No, it's not a portability issue, because we have our own copy for
platforms without it; see src/port/.)
