This is integration WL. InnoDB tablespaces  will have SDI stored
within the .ibd. The only tablespaces that don't have SDI are
undo, temporary.

After shutdown, the SDI from IBD files can be dumped using

ibd2sdi t1.ibd > t1.sdi

This WL combines the server side changes contributed by
Dyre Tjeldvoll <dyre.tjeldvoll@oracle.com> and InnoDB changes
done by Satya Bodapati <satya.bodapati@oracle.com>
