Update to 1.5.0

Upstream changes:
libisofs-1.5.0.tar.gz Sat Sep 15 2018
===============================================================================
* New API call iso_image_get_ignore_aclea(),
  new iso_image_set_ignore_aclea() and iso_file_source_get_aa_string()
  flag bit3 to import all xattr namespaces
* New API calls iso_image_was_blind_attrs(), iso_local_set_attrs_errno().
* New flag bit7 with iso_local_set_attrs() to avoid unnecessary write attempts.
* New return value 2 of IsoFileSource.get_aa_string() and iso_local_get_attrs().
* Now putting user defined padding after appended partitions.
* Bug fix: Add-on sessions with partition offset claimed too many blocks as
          size. Regression of version 1.4.8.
* Bug fix: Long Joliet names without dot were mangled with one character too
          many. Long Joliet names with leading dot were mangled one char
          too short.
* Bug fix: Reading beyond array end for HFS+ production caused SIGSEGV with
          FreeBSD 11 CLANG -O2. Thanks ASX of GhostBSD.

libisofs-1.4.8.tar.gz Tue Sep 12 2017
===============================================================================
* Bug fix: iso_read_opts_set_no_rockridge() did not prevent reading of root
          SUSP.
* Bug fix: Non-SUSP data in System Use Area prevented image loading if
          Rock Ridge was enabled. Thanks to Jonathan Dowland.
* Bug fix: Protective MBR for GPT could emerge with boot flag set.
* Bug fix: Appended partitions of size >= 4 GiB led to abort with error message
          "FATAL : ISO overwrite". Thanks to Sven Haardiek.
* Bug fix: Bit 15 of iso_write_opts_set_system_area did not work with generic
          MBR.
* Bug fix: Keeping and patching of loaded boot images failed.
          Regression by version 1.4.4.
* Bug fix: Program crashes by intentionally wrong ISO image input.
          Found by American Fuzzy Lop and Jakub Wilk.
          Debian bug reports: 872372, 872475, 872545, 872590, 872761.
* New API calls el_torito_set_full_load(), el_torito_get_full_load().
* New API call iso_write_opts_set_iso_mbr_part_type().

libisofs-1.4.6.tar.gz Fri Sep 16 2016
===============================================================================
* Bug fix: SIGSEGV by NULL when a data file was larger than ISO level allows.
* Bug fix: Interpretation of 17 digit timestamps was wrong.
* New API calls iso_generate_gpt_guid() and iso_write_opts_set_gpt_guid().
* Made several pseudo-random ids reproducible by overriding volume modification
  time.

libisofs-1.4.4.tar.gz Fri Jul 01 2016
===============================================================================
* Bug fix: HFS+ production could cause MBR partition of type 0xEE without GPT.
* Bug fix: Protective MBR was not produced if no System Area data are given.
* Bug fix: Protective MBR was not recognized if partition is appended.
* Bug fix: The HFS+ filesystem was not marked in GPT of GRUB2 hybrid layout.
* Bug fix: HFS+ directories could announce more children than they actually
          have.
* Bug fix: At image loading time GRUB2 MBR was not recognized if the partition
          table is not the protective one as described by UEFI.
* Bug fix: Oversized text in ISO_SYSAREA_REPORT_DOC_ALPHA.
          Thanks to Etienne Bergeron.
* New pseudo path for El Torito boot images:
  --interval:appened_partition_N:all::
* New bit15 with options of iso_write_opts_set_system_area() to enforce
  MBR bootable/active flag.
* New API calls iso_write_opts_set_appended_as_apm(),
  iso_write_opts_set_part_like_isohybrid().
* Introduced image size tolerance of 300 kB in order to recognize SUN Disk
  Label that was generated by genisoimage -B "...".
* Added "extern C" to libisofs.h
* Removed option --silent from libtool runs.

libisofs-1.4.2.tar.gz Sat Nov 28 2015
===============================================================================
* Bug fix: zisofs compression caused SIGSEGV (by reading) with files larger
          than 524160 KiB.
* Bug fix: iso_node_get_name() of root node returned NULL pointer rather than
          an empty string
* Bug fix: Names read from Joliet tree where stripped of trailing ";1"
* Now sorting the data file content extents by ECMA-119 tree, rather than
  by the red-black tree which shall consolidate files with identical
  source object.
* New API call iso_read_opts_set_ecma119_map().
* New AAIP variable isofs.nt records name truncation parameters.
* Rectified handling of oversized filenames by new API calls:
  iso_image_set_truncate_mode, iso_image_get_truncate_mode,
  iso_truncate_leaf_name, iso_image_set_node_name, iso_image_tree_clone,
  iso_image_add_new_dir, iso_image_add_new_file, iso_image_add_new_special,
  iso_image_add_new_symlink, iso_image_dir_get_node, iso_image_path_to_node
* Result of a Coverity audit: 50+ code changes, but no easy-to-trigger bugs

libisofs-1.4.0.tar.gz Sun May 17 2015
===============================================================================
* Bug fix: iso_image_report_system_area() caused SIGSEGV by NULL if no valid
          ISO 9660 image was loeaded. Thanks to OmegaPhil.
* Bug fix: A SIGSEGV could happen when loading a faulty ISO filesystem.
          Debian bug 774152. Thanks to Jakub Wilk.
* Bug fix: Rock Ridge Continuation Area could be produced crossing a block
          boundary. This is heavily disliked by the Linux kernel and spoils
          the representation of directories which contain many symbolic links.
* Bug fix: If iso_write_opts_set_hardlinks() enabled automatic inode numbers,
          then they did not get into effect with nodes were zisofs decoder
          filters got attached during the image load process.
* Bug fix: The header indicator of the last El Torito catalog section header
          was set to 0x90 rather than 0x91 if more than one boot image is in
          that section.
* Bug fix: Only 128 bytes of an emerging GPT header block were zeroized.
* Bug fix: iso_image_report_system_area() did not show GPT partitions of
          size 0.
* Bug fix: A zero sized GPT partition was marked after the last appended
          GPT partition.
* Bug fix: GPT production did not yield proper results with appended sessions
          or with TOC emulation enabled.
* Increased default weight of El Torito boot catalog to 1 billion.
* Improved handling of cylinder alignment if the resulting image size is not
  divisible by 2048. Old behavior was to not align. New is to pad up by a
  few blocks of 512 bytes.
* New API call iso_write_opts_set_appended_as_gpt()
  and marking of appended partitions in GPT if GPT emerges for other reasons.
* New system area type 6 = DEC Alpha SRM boot sector.
  New API calls iso_image_set_alpha_boot(), iso_image_get_alpha_boot().
  Thanks to Helge Deller.
* New API object iso_interval_reader. Enabling flag bits for older API calls
  iso_write_opts_set_prep_img(), iso_write_opts_set_efi_bootp(),
  and iso_write_opts_set_partition_img().
