Add support for exposing public QProperty members in the meta-object system
At the moment this makes the type as well as the setter/getter available through the meta-call as well as the ability to register observers and bindings. Only QProperty members that are annotated with Q_PROPERTY(type name) are made public through the meta-object. Change-Id: I16b98fd318122c722b85ce61e39975284e0c2404 Reviewed-by: Ulf Hermann <>
