resizeToContents - move some of sizeHint into separate functions
Some of sizeHintForColumn is now moved into widthHintForIndex.
(and in QTreeView some of sizeHintForRow into heightHintForIndex)
This makes the code a bit more readable and it prepares some
extensions that will use these functions more. There should
be no semantic changes in this patch.
In releasemode this does not seem to have a performance cost.
(QTableView actually seemed to be a bit faster)
