Simplify the tests that are present in MySQL 5.7. Make the table smaller while generating enough undo log. Do not unnecessarily drop tables. trx_purge_initiate_truncate(): Remove two crash injection points (before and after normal redo log checkpoint), because they are not adding any value. Clarify some messages. trx_sys_create_rsegs(): Display the number of active undo tablespaces. srv_undo_tablespaces_init(): When initializing the data files, do not leave srv_undo_tablespaces_active at 0. Do not display that number; let trx_sys_create_rsegs() display it once the final number is known. innodb_params_adjust(): Adjust parameters after startup. innobase_init(): Do not allow innodb_max_undo_size to be less than SRV_UNDO_TABLESPACE_SIZE_IN_PAGES. This avoids unnecessary repeated truncation of undo tablespaces when using innodb_page_size=32k or innodb_page_size=64k.
