riched20: Rewrite of scrolling and some redrawing code.

Replaces duplicated scrolling code with re-usable functions.
Removes excessive boundary checking on scroll code, since that's done
in the scrollbar control anyways.
Properly separates repaint calls based on what has changed.
Send EN_UPDATE and EN_CHANGE at the right places.
Only call EnsureVisible on changes, not all repaints.
