listview and LVS_OWNERDATA problems update

[Dan Kegel]

I just revisited
http://bugs.winehq.org/show_bug.cgi?id=1268
and found that things are improved, but not fully working;
there is corruption to the left of column 1 in the demo app.

I have not yet rechecked
http://bugs.winehq.org/show_bug.cgi?id=1404
to see how well that demo app is doing.
