In order to avoid external dependencies on implementation details,
this change replaces RadosError with the unexported radosError. In case
some application really needs access to the integer value, it can use
the pattern
var errno interface{ Errno() int }
if errors.As(err, errno) { ... errno.Errno() ... }
