Review Comment:
> +1, we can make sure the static method caller have an efficient
implementation of `skipBytes()`(base on `seek()`), Just i guess the `seek()`
has an impact on performance, let me try..
Yes, if `skipBytes()` is not efficient (InputStream based DataInput), you
can't use that specialized method anyways. IndexInput has an efficient default
implementation, so no need to change anything. So we do not need to optimize
anything.
Just call skipBytes() and test performance.
