+Description: Let libisoburn and xorriso demand libjte version >= 2.0.0.
+ Use the new function names and offer the new Jigdo related options.
+ .so numbering gets incremented from libisoburn.so.1.109.0 to 
+ libisoburn.so.1.110.0  to reflect the increase of demand in comparison to 
+ unpatched libisoburn-1.5.2.
+ The ./configure test now checks availability of new libjte2 function
+ libjte_set_checksum_algorithm. If not present, then libjte will not be used.
+ (Compile time and run-time checks would refuse if libjte < 2.0.0 is found.)

+-drive_class "harmless"|"banned"|"caution"|"clear_list" disk_pattern
+     Add a drive path pattern to one of the safety lists or make those
+     lists empty.  There are three lists defined which get tested in the
+     following sequence:
+     If a drive address path matches the "harmless" list then the drive
+     will be accepted.  If it is not a MMC device then the prefix
+     "stdio:" will be prepended automatically.  This list is empty by
+     default.
+     Else if the path matches the "banned" list then the drive will not
+     be accepted by 'xorriso' but rather lead to a FAILURE event.  This
+     list is empty by default.
+     Else if the path matches the "caution" list and if it is not a MMC
+     device, then its address must have the prefix "stdio:" or it will
+     be rejected.  This list has by default one entry: "/dev".
+     If a drive path matches no list then it is considered "harmless".
+     By default these are all paths which do not begin with directory
+     "/dev".
+     A path matches a list if one of its parent paths or itself matches
+     a list entry.  Address prefix "stdio:" or "mmc:" will be ignored
+     when testing for matches.
+     By pseudo-class "clear_list" and pseudo-patterns "banned",
+     "caution", "harmless", or "all", the lists may be made empty.
+     E.g.: -drive_class clear_list banned
+     One will normally define the -drive_class lists in one of the
+     'xorriso' Startup Files.
+     Note: This is not a security feature but rather a bumper for the
+     superuser to prevent inadverted mishaps.  For reliably blocking
+     access to a device file you have to deny its rw-permissions in the
+     filesystem.
+-drive_access "exclusive"|"shared":"unrestricted"|"readonly"
+     Control whether device file locking mechanisms shall be used when
+     acquiring a drive, and whether status or content of the medium in
+     the drive may be altered.  Useful and most harmless are the setting
+     "shared:readonly" and the default setting "exclusive:unrestricted".
+
+     "exclusive" enables tests and locks when acquiring the drive.  It
+     depends on the operating system which locking mechanisms get
+     applied, if any.  On GNU/Linux it is open(O_EXCL). On FreeBSD it is
+     flock(LOCK_EX).
+     "shared" disables the use of these mechanisms to become able to
+     acquire drives which are mounted, or opened by some process, or
+     guarded by /dev/pktcdvd*.
+     "unrestricted" enables all technically appropriate operations on an
+     acquired drive.  "shared:unrestricted" risks to get own burn runs
+     spoiled by other processes or to vice versa spoil activities of
+     such processes.  So use "exclusive:unrestricted" unless you know
+     for sure that "shared" is safe.
+     "readonly" disables operations which might surprise a co-user of
+     the drive.  For -outdev these are formatting, blanking, writing,
+     ejecting.  For -indev this is ejecting.  Be aware that even reading
+     and drive status inquiries can disturb an ongoing burn run on
+     CD-R[W] and DVD-R[W].

+@cindex Device file locking, -drive_access
+Control whether device file locking mechanisms shall be used when acquiring a
+drive, and whether status or content of the medium in the drive may be
+altered. Useful and most harmless are the setting "shared:readonly"
+and the default setting "exclusive:unrestricted".
+@*
+"exclusive" enables tests and locks when acquiring the drive. It depends on the
+operating system which locking mechanisms get applied, if any. On GNU/Linux
+it is open(O_EXCL). On FreeBSD it is flock(LOCK_EX).
+@*
+"shared" disables the use of these mechanisms to become able to acquire drives
+which are mounted, or opened by some process, or guarded by /dev/pktcdvd*.
+@*
+"unrestricted" enables all technically appropriate operations on an acquired
+drive. "shared:unrestricted" risks to get own burn runs spoiled by other
+processes or to vice versa spoil activities of such processes. So use
+"exclusive:unrestricted" unless you know for sure that "shared" is safe.
+@*
+"readonly" disables operations which might surprise a co-user of the drive.
+For -outdev these are formatting, blanking, writing, ejecting. For -indev
+this is ejecting. Be aware that even reading and drive status inquiries can
+disturb an ongoing burn run on CD-R[W] and DVD-R[W].
