vt: wip: implement scrolling region

This is largely untested, but existing scrolling code has been
converted to using a terminal-global scrolling region that is defined
as start-end of the scrollable region.

This is compared to the old code where the scrolling region where
defined in terms of marginals, counted in lines from top and from
bottom.
