QQmlAnyBinding is meant to abstract over the differences between
classical, QQmlAbstractBinding derived bindings and the newer
QPropertyBindingPrivate based ones. It can be used to store, receive,
remove, create and set bindings of both types.
In addition, this patches adds the functionality to create a
QQmlPropertyBinding from a code string, which was so far only
possible with QQmlBinding; and adds a few methods to QBiPointer to ease
the implementation of QQmlAnyBinding.
