Add QVariant container iteration API.
A new set of classes is introduced for iterating over the contents of a container within a QVariant without knowing the exact type of the container, but with the guarantee that the element type within the container is a metatype. The implementation of the iterable interface uses the stl-compatible container API so that we can also iterate over stl containers, or any other container which also conforms to stl norms. This enables the functionality in the bug report. Task-number: QTBUG-23566 Change-Id: I92a2f3458516de201b8f0e470982c4d030e8ac8b Reviewed-by: Stephen Kelly <>
