Move the cursor in the result set to a new position according to mode.

If `!mode` is ``'relative'`` (default), `!value` is taken as offset to
the current position in the result set; if set to ``'absolute'``,
`!value` states an absolute target position.

Raise `!IndexError` in case a scroll operation would leave the result
set. In this case the position will not change.
