 {{{

 Introduce `bp_pre_schema_upgrade()` and use it to drop old `meta_key`
 indexes.

 After [9695], BP tries to update existing indexes using `dbDelta()`, but
 `dbDelta()` cannot `DROP INDEX` properly. So we must run a separate
 routine
 before the regular schema updates. See WP's `pre_schema_upgrade()`.

 See #6346.
