Peter Dillinger 4e258d3e63 Fix backup/restore in stress/crash test (#7357) ... Summary: (1) Skip check on specific key if restoring an old backup (small minority of cases) because it can fail in those cases. (2) Remove an old assertion about number of column families and number of keys passed in, which is broken by atomic flush (cf_consistency) test. Like other code (for better or worse) assume a single key and iterate over column families. (3) Apply mock_direct_io to NewSequentialFile so that db_stress backup works on /dev/shm. Also add more context to output in case of backup/restore db_stress failure. Also a minor fix to BackupEngine to report first failure status in creating new backup, and drop another clue about the potential source of a "Backup failed" status.
