04bd86a4b0 lib: Update getopt.c from Gnulib with modifications.
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.

56b42be728 lib: Add getopt-cdefs.h for getopt_long update.
This was modified slightly from Gnulib. In Gnulib, it expects the
@HAVE_SYS_CDEFS_H@ to be replaced. Instead, we can set HAVE_SYS_CDEFS_H
on systems that have it and avoid copying another file into the build
directory. Since we are not using gnulib-tool, copying extra files
requires extra build system updates (and special handling with CMake) so
we should avoid when possible.

9834e591a4 lib: Copy new header files from Gnulib without modification.
The getopt related files have changed from Gnulib by splitting up
getopt.in.h into more modular header files. We could have kept
everything in just getopt.in.h, but this will help us continue to update
in the future.

aff1b479c7 lib/getopt*.c: Include <config.h> only HAVE_CONFIG_H is defined.
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.

02ddf09bc3 Put the interesting parts of XZ Utils into the public domain.
Some minor documentation cleanups were made at the same time.

e114502b2b 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

5286723e0d Get rid of no-NLS gnulib. I don't know how to get it
working with Automake. People who want smaller lzmadec
should use --disable-nls on non-GNU systems.
