Fix the API for resetting QAbstractItemModels.
This commit deprecates the QAIM::reset() method, and adds beginResetModel()
and endResetModel() methods, addressing Qt issue 247023.
http://www.qtsoftware.com/developer/task-tracker/index_html?method=entry&id=247023
If models and proxies use QAIM::reset() alone, then proxies will
emit modelAboutToBeReset after its source model is reset. This means that mapToSource
will not behave as expected (Will always return an invalid index) in a slot connected
to modelAboutToBeReset.
The usecase for this is maintaining viewstate (which items are selected, expanded)
when the model is reset. See BrowserWidget::modelChanged here:
