Revert back to a macro so that list(APPEND CMAKE_REQUIRED_DEFINITIONS)
will affect the calling scope. I had forgotten that while CMake
functions inherit the variables from the parent scope, the changes
to them are local unless using set(... PARENT_SCOPE).
This also means that the commit message in 5bb77d0920dc is wrong. The
commit itself is still fine, making it clearer that -DHAVE_SYS_PARAM_H
is only needed for specific check_c_source_compiles() calls.

Define NetBSD and Darwin/macOS feature test macros. Autoconf defines
these too (and a few others).
Define the macros on Windows except with MSVC. The _GNU_SOURCE macro
makes a difference with mingw-w64.
Use a function instead of a macro. Don't take the TARGET_OR_ALL argument
because there's always global effect because the global variable
CMAKE_REQUIRED_DEFINITIONS is modified.
All translators know that --command-line-options must not be translated.
With some other strings it's not obvious when the untranslated string
must be preserved. These comments hopefully help.
The deprecated aliases are lzcmp, lzdiff, lzless, lzmore,
lzgrep, lzegrep, and lzfgrep. The commands that start with
the xz prefix have identical behavior, for example, both
lzgrep and xzgrep handle all supported file formats.
This doesn't affect lzma, unlzma, lzcat, lzmadec, or lzmainfo.
The last release of LZMA Utils was made in 2008, but the lzma
compatibility alias for the gzip-like tool is still in common use.
Deprecating it would cause unnecessary breakage.
Nowaways $(top_builddir)/lib/getopt.h depends on headers in
$(top_srcdir)/lib, so both have to be in the include path.
CMake-based build already did this.

Now one can pass gl_replace_getopt=yes to configure to force the use
of GNU getopt_long from the lib directory. This only checks that the
value of gl_replace_getopt is non-empty, so one cannot force the
replacement to be disabled.

Make it clearer that translations cannot be accepted if they don't
come via the Translation Project.
Column headings have been handled automatically for years and now --help
is autowrapped too, so the related instructions can be removed.
Make it work for out-of-tree builds without requiring one to specify
the location of the xz executable.
Add xz --filters-help.
Make the output shorter by reducing the number of xz -lvv test files.
Show the value of LANGUAGE environment variable.
Show the xz.git version using git describe --abbrev=8 instead of =4.
Since there are no spaces between words, the unsophisticated automatic
word wrapping code needs some help. Compared to the version in the
Translation Project, I added a few \t characters which the word
wrapping code interprets as zero width spaces (hopefully they are
placed correctly). These edits can be seen with this command:
grep -v ^# po/zh_TW.po | grep --color -F '\t'
