The VSERPORT_CHANGE event was added ine2ae6159. The patch for this event was prepared at a time when this file was gone, even though it got applied immediately afterdfab4892restored this file. Duplicate the documentation into this file, so that anyone using this file instead of qapi will not miss out on this new event. * docs/qmp/qmp-events.txt (VSERPORT_CHANGE): Add.
