QScroller merge, part 1

This merge consists of the actual kinetic scroller implementation, its
autotests plus a few examples.  QAbstractScrollArea and QAbstractItemView
have been extended to support the new scroll events.

The complete history is in

(part 2 is the QML Flickable replacement / part 3 is QWebView support)
