patch 9.0.0445: when opening/closing window text moves up/down

Browse Source 
Problem:    When opening/closing window text moves up/down.
Solution:   Add the 'splitscroll' option.  When off text will keep its
            position as much as possible.

The value of this option determines the scroll behavior when opening,
closing or resizing horizontal splits. When "on", splitting a window
horizontally will keep the same relative cursor position in the old and
new window, as well windows that are resized. When "off", scrolling
will be avoided to stabilize the window content. Instead, the cursor
position will be changed when necessary. In this case, the jumplist
will be populated with the previous cursor position. Scrolling cannot
be guaranteed to be avoided when 'wrap' is enabled.
