This renames receiveProps and changes it to take the next component to copy props from instead of just the props. That is, component.receiveComponent(nextComponent, transaction) instead of component.receiveProps(nextComponent.props, transaction) This is a precursor to adding contexts, which will also need to get propagated just like props. This change allows ReactCompositeComponent to override `receiveProps` and do something like this._pendingContext = nextComponent.context;
