Historically, InnoDB split the redo log into at least 2 files. MDEV-12061 allowed the minimum to be innodb_log_files_in_group=1, but it kept the default at innodb_log_files_in_group=2. Because performance seems to be slightly better with only one log file, and because implementing an append-only variant of the log would require a single file, let us define the default to be 1, and have innodb_log_file_size=96M, to retain the same default total size.
