Insert a QList in another QList at a position

Inserting the content of a QList in an other QList can only be done at the end. It is sometimes useful to insert the content in an arbitrary position in the list (with distributed merge algorithms for example).

A method like the following would be useful in those cases:
void QList::insert ( int i, const QList<T> & value );

This cannot be made effectively from the public API, it need to use the private delegate.
