Analysis: There are 2 server variables- "old_mode" and "old". "old" is no longer needed as "old_mode" has replaced it (however still used in some places in the code). "old_mode" and "old" has same purpose- emulate behavior from previous MariaDB versions. So they can be merged to avoid confusion. Fix: Deprecate "old" variable and create another mode for @@old_mode to mimic behavior of previous "old" variable. Create specific modes for specifix task that --old sql variable was doing earlier and use the new modes instead.
