Introduce required properties to QML
[ChangeLog][QtQml]
"required" is now a (contextual) keyword in QML, and users can
mark properties with it to specify that those properties must be set
when the component gets instantiated.
This can be done either declaratively via standard property
bindings from QML, or imperatively by using the functions to set initial
properties (QQmlCompoent::setInitalProperties and related functions in
C++, Qt.createObject, Loader.setSource,... in QML/JS).
Logic has been added to QQmlComponent::create and the various QQmlIncubator
classes to verify that the required properties were set. If properties
marked as required are not set, a warning will be printed at runtime,
and the component will not be created.
