v0.11.14: audit fixes — trailing sectors, verify stop, SCSI sense, O_CLOEXEC

Browse Source 
Fix trailing sectors dropped at extent boundaries when sector_count % 3 != 0.
Add verify_title stop support via progress callback returning bool.
Add O_CLOEXEC on all SCSI fd opens to prevent leak to child processes.
Fix SCSI sense descriptor format detection (0x72/0x73 vs 0x70/0x71).
