Mode "without_update" avoids hardlink processing during update commands.

xorriso commands which extract files from an ISO image try to hardlink files
with identical inode number. Normally this applies only to files which
get extracted during execution of that same command. One may surround a group
of extraction commands by -hardlinks "start_extract" and
-hardlinks "end_extract" to allow hard linking among their extracted files.
