Starting with commit baf276e6d4a44fe7cdf3b435c0153da0a42af2b6 (MDEV-19229) the parameter innodb_undo_tablespaces can be increased from its previous default value 0 while allowing an upgrade from old databases. We will change the default setting to innodb_undo_tablespaces=3 so that the space occupied by possible bursts of undo log records can be reclaimed after SET GLOBAL innodb_undo_log_truncate=ON. We will not enable innodb_undo_log_truncate by default, because it causes some observable performance degradation. Special thanks to Thirunarayanan Balathandayuthapani for diagnosing and fixing a number of bugs related to this new default setting. Tested by: Matthias Leich, Axel Schwenke, Vladislav Vaintroub (with both values of innodb_undo_log_truncate)
