During native table rebuild or index creation, InnoDB used to skip redo logging and write MLOG_INDEX_LOAD records to inform crash recovery and Mariabackup of the gaps in redo log. This is fragile and prohibits some optimizations, such as skipping the doublewrite buffer for newly (re)initialized pages (MDEV-19738). row_merge_write_redo(): Remove. We do not write MLOG_INDEX_LOAD records any more. Instead, we write full redo log. FlushObserver: Remove. fseg_free_page_func(): Remove the parameter log. Redo logging cannot be disabled. fil_space_t::redo_skipped_count: Remove. We cannot remove buf_block_t::skip_flush_check, because PageBulk will temporarily generate invalid B-tree pages in the buffer pool.
