extend the QObjectPrivate::connectedSignals bitfield to make space

for all the required NOTIFY signals we need for QML bindings.
An additional internal function QMetaObject::isConnected() allows
to query the bits, or you use connectedSignals[0] if you know that
the signal in question has a QMetaObject::indexOfSignal() < 32.
