       For this record to be of any use for Recovery, we need the upper
       MySQL layer to be crash-safe, which it is not now (that would require
       work using the ddl_log of sql/sql_table.cc); when it is, we should
       reconsider the moment of writing this log record (before or after op,
       under THR_LOCK_maria or not...), how to use it in Recovery.
       For now this record can serve when we apply logs to a backup,
       so we sync it. This happens before the data file is created. If the
       data file was created before, and we crashed before writing the log
       record, at restart the table may be used, so we would not have a
       trustable history in the log (impossible to apply this log to a
       backup). The way we do it, if we crash before writing the log record
       then there is no data file and the table cannot be used.
       @todo Note that in case of TRUNCATE TABLE we also come here; for
       Recovery to be able to finish TRUNCATE TABLE, instead of leaving a
       half-truncated table, we should log the record at start of
       maria_create(); for that we shouldn't write to the index file but to a
       buffer (DYNAMIC_STRING), put the buffer into the record, then put the
       buffer into the index file (so, change _ma_keydef_write() etc). That
       would also enable Recovery to finish a CREATE TABLE. The final result
       would be that we would be able to finish what the SQL layer has asked
       for: it would be atomic.
       When in CREATE/TRUNCATE (or DROP or RENAME or REPAIR) we have not
       called external_lock(), so have no TRN. It does not matter, as all
       these operations are non-transactional and sync their files.
