Bug: 409355667, 40891923
Original change's description:
> HistoryDatabase: improve migration code.
>
> 1. Delete old migration code. Chromium generally doesn't support
> forward-migrating data that is more than 2 years old. This change
> deletes migration code that has been live for at least two years. This
> reduces binary bloat (-17kB on Android arm32) and removes some migration
> anti-patterns, which hopefully will help prevent future code being added
> that uses these patterns. See crbug.com/409355667
>
> 2. Use compatible version correctly. This value is meant to represent
> the oldest version of Chromium *code* that can use the current version
> of Chromium *data*, i.e. support for downgrades. Chromium generally
> doesn't attempt to support downgrading, but the migrations to v69 and
> v70 were backwards compatible, so code for 68 should be fine to run with
> data from 69+. This value was not actually being set at all previously.
>
> 3. Handle failure to update meta table.
