Change C++ parameter type used for var parameters in QML declared signals
"signal someSignal(var foo)" mapped to foo being of type QVariant. Unfortunately that is a "lossy" type and it cannot represent all JavaScript values, including for example function closures (as reported in the JIRA bug). Instead we should use QJSValue. It is an important behavioural change because it affects the presumably rare case of somebody declaring a signal in QML with such a parameter and connect to it from C++ (or trying to emit it) - in that situation the code needs to be changed.
