srv_start_state_t: Document the flags. Replace SRV_START_STATE_STAT with SRV_START_STATE_REDO. The srv_bg_undo_sources replaces the original use of SRV_START_STATE_STAT. dict_stats_thread_started, buf_dump_thread_started, buf_flush_page_cleaner_thread_started: Remove (unused). srv_shutdown_all_bg_threads(): Always wait for the I/O threads to exit, also in read-only mode. os_thread_free(): Remove.
