ChangeLog: 

        Partially revert revision 2243173005802c676dee57f87bb67d83b84256c0,
        and add some more safety nets and a special migration tool.

        * README.changesets: Revert all changes.
        * schema.sql: Restore the definitions of the manifests,
        manifest_deltas, and manifest_certs tables, but move them to the
        end of the file and label them obsolete.
        * schema_migration.cc: Add dump functions for our local data structures.
        (migrate_add_ccode_and_drop_manifest_tables):
        Rename migrate_add_ccode.  Delete code to drop tables.
        (migration_events): Update.
        (get_schema_data): Rename calculate_schema_id; calculate the hash here.
        (temporarily_allowed_tables, compare_schema_hash): Delete.
        (find_migration): Can compare hashes directly.  Use 'm' not 'p'
        for migration_events iterator variable, for consistency.
        (describe_sql_schema): Use calculate_schema_id.
        (migrate_sql_schema): Similarly.  Add a whole bunch of MMs.
        * tests/schema_migration: Update.

        * database.cc (database::check_format): May assume 'manifests'
        table exists.  Condition pre/post-rosterification check on
        whether it is empty.
        (database::debug): Call ensure_open_for_maintenance, so 'db execute'
        works on databases with invalid schemas.
        (database::delete_existing_manifests): Revert; do not drop tables.
        * tests/schema_migration_bad_schema/possible.dump: Restore
        manifest tables.

        * contrib/recreate-manifest-tables.sh: New file.
        * contrib/mashschema.cc: Delete.
