An Xclose equivalent for prepared handles should be made available, so we can close the prepared structure on the server, as soon as the client detects it is no longer necessary (e.g. Java garbage collector initiates a call to finalize()).

Perhaps we can reuse Xclose if we would guarantee resultsets and prepared handles never to have the same ID. Would allow for easy closing of a prepared handle from the client's perspective though, since resultsets and prepared handles are effectively the same in the protocol.
