Re-separated component and event setup. It would be nice to combine

these, but if we do, we need to put them in an entirely new API,
deprecating the old apis.  Existing software may use the component
setup and then new it's own setup for objectEventNotify. If the
component setup sets up this handler, then it will be doubly setup,
causing tests to fail.
