Rename this function to GenericXLogRegisterBuffer() to make it clearer what it does, and leave room for other sorts of "register" actions in future. Also, replace its "bool isNew" argument with an integer flags argument, so as to allow adding more flags in future without an API break. Alexander Korotkov, adjusted slightly by me
