We don't use TABLEREVERT(.F.) to revert a row; instead, we use cancel
(). The equivalent to TABLEREVERT(.T.) is cancelAll().

The equivalent to OLDVAL() is kept in a memento object for each row.
We don't have a way to access that from the bizobj because there has
never been a use case for it. It is used internally to figure out
just what has changed in a record, in order to create the appropriate
SQL Update command.
