Oh well, big messy commit again. Some highlights:

  - Updated to the latest, probably final file format version.
  - Command line tool reworked to not use threads anymore.
    Threading will probably go into liblzma anyway.
  - Memory usage limit is now about 30 % for uncompression
    and about 90 % for compression.
  - Progress indicator with --verbose
  - Simplified --help and full --long-help
  - Upgraded to the last LGPLv2.1+ getopt_long from gnulib.
  - Some bug fixes
