CMake: Fix tuklib_use_system_extensions
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.

CMake: Revise tuklib_use_system_extensions
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.

Docs: Add a few TRANSLATORS comments to man pages
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.

Scripts: Mark the LZMA Utils script aliases as deprecated
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.

Build: Fix out-of-tree builds when using the replacement getopt_long
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.

Build: Allow forcing the use of the replacement getopt_long
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.

Translations: Update Chinese (traditional) translation
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:

Build: Update posix-shell.m4 from Gnulib
Tabs have been converted to spaces and a "serial" number has been
added. The previous version was from 2008/2009. There are no functional
changes since then but now it's clearer that the copy in XZ Utils
isn't outdated.
The new file was picked from the Gnulib commit 81a4c1e3b7692e95c0806d948cbab9148ad85ef2. A later commit adds
a warranty disclaimer to the license, which obviously is fine,
but I didn't find a SPDX license identifier for the new license,
so for simplicity I used the earlier commit.

Build: Check for -fsanitize= also in $CC
People may put -fsanitize in CC instead of CFLAGS so check both.
Landlock sandbox isn't compatible with sanitizers so it's nice
to catch the incompatible options at configure time.
Don't attempt to do the same in CMakeLists.txt; the check for
CMAKE_C_FLAGS / CFLAGS shall be enough there. The extra flags from
the CC environment variable go into the undocumented internal variable
CMAKE_C_COMPILER_ARG1 (all flags from CC go into that same variable).
Peeking the internal variable merely for improved diagnostics isn't
worth it.

Windows: Avoid an error message on broken pipe
Also make xz not process more input files after a broken pipe has
been detected. This matches the behavior on POSIX. If all files
are being written to standard output, trying with the next file is
pointless when it's known that standard output won't accept more data.
xzdec already stopped after the first error. It does so with all
errors, so it differs from xz:
$ xz -dc not_found_1 not_found_2
xz: not_found_1: No such file or directory
xz: not_found_2: No such file or directory
$ xzdec not_found_1 not_found_2
xzdec: not_found_1: No such file or directory

Windows: Disable MinGW-w64's stdio functions in size-optimized builds
This only affects builds with UCRT. With legacy MSVCRT, the replacement
functions are always enabled.
Omitting the MinGW-w64 replacements saves over 20 KiB per executable.
The downside is that --enable-small or XZ_SMALL=ON disables thousand
separator support in xz messages. If someone is OK with the slower
speed of slightly smaller builds, lack of thousand separators won't
matter.
Don't override __USE_MINGW_ANSI_STDIO if it is already defined (via
CPPFLAGS or such method).

liblzma: memcmplen.h: Use 8-byte method on 64-bit unaligned archs
Previously it was enabled only on x86-64 and ARM64 when also support
for unaligned access was detected or manually enabled at built time.
In the default build configuration, the 8-byte method is now enabled
also on 64-bit RISC-V and 64-bit PowerPC (both endiannesses). It was
reported that on big endian POWER9, encoding time may reduce 12-13 %.
This change only affects builds with GCC and Clang because the code
uses __builtin_ctzll or __builtin_clzll.
