Stop supporting the additional *trunc.log files that were introduced via MySQL 5.7 to MariaDB Server 10.2 and 10.3. DB_TABLESPACE_TRUNCATED: Remove. purge_sys.truncate: A new structure to track undo tablespace file truncation. srv_start(): Remove the call to buf_pool_invalidate(). It is no longer necessary, given that we no longer access things in ways that violate the ARIES protocol. This call was originally added for innodb_file_format, and it may later have been necessary for the proper function of the MySQL 5.7 TRUNCATE recovery, which we are now removing. trx_purge_cleanse_purge_queue(): Take the undo tablespace as a parameter. trx_purge_truncate_history(): Rewrite everything mostly in a single function, replacing references to undo::Truncate. recv_apply_hashed_log_recs(): If any redo log is to be applied, and if the log_sys.log.subformat indicates that separately logged truncate may have been used, refuse to proceed except if innodb_force_recovery is set. We will still refuse crash-upgrade if TRUNCATE TABLE was logged. Undo tablespace truncation would only be logged in undo*trunc.log files, which we are no longer checking for.
