The code maintains the prior modifications of conditionally including
config.h and disabling NLS support.
_GL_UNUSED is repalced with the simple cast to void trick. _GL_UNUSED
is only used for these two parameters so its simpler than having to
define it.
The CMake-based build doesn't use config.h.
Up-to-date getopt_long in Gnulib is LGPLv2 so at some
point it could be included in XZ Utils too but for now
this commit is enough to make CMake-based build possible.
- 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
