Release Notes:
* https://github.com/tukaani-project/xz/releases/tag/v5.8.2
* liblzma:
    - Fix the build on ARM64 on glibc versions older than
      2.24 (2016). They don't have HWCAP_CRC32 in <sys/auxv.h>.
    - Disable CLMUL CRC code when building for 32-bit x86 with
      old MSVC versions. This avoids a compiler bug. The exact
      compiler version in which the issue was fixed is unknown,
      but VS 2022 17.13 (MSVC 19.43.34808) is known to work, so
      CLMUL CRC on 32-bit x86 is disabled with MSVC versions
      older than that.
* xz:
    - Add a workaround for Red Hat Enterprise Linux 9 kernel bug
      which made xz fail with "xz: Failed to enable the sandbox".
      It only occurs with xz 5.8.0 and 5.8.1 binaries built for
      other distros. For example, running Debian 13 in a container
      on RHEL/CentOS 9 would trigger the issue.
      The bug was introduced in RHEL 9 kernel 5.14.0-603.el9
      (2025-07-30) and fixed in 5.14.0-648.el9 (2025-12-05).
      However, as of writing, the fixed kernel isn't available
      to RHEL 9 users yet, so including the workaround in this
      xz release seems reasonable. The workaround will be removed
      when it's no longer needed.
      xzdec was also affected by this issue.
    - On AIX, don't use fsync() on directories because it fails.
    - Fix the build on Emscripten.
    - Fix the build on clang-cl on Windows.
    - Take resource limits (RLIMIT_DATA, RLIMIT_AS, and RLIMIT_VMEM)
      into account when determining the default memory usage limit
      for multithreaded mode. This should prevent xz from failing
      when a resource limit has been set to a value that is less
      than 1/4 of total RAM. Other memory limits can still trigger
      the same issue, for example, Linux cgroup v2 memory.max.
* Build systems:
    - When symbol versioning is enabled, pass --undefined-version
      to the linker if the option is supported. This fixes the
      build when using LLVM's lld and some liblzma features have
      been disabled at build time.
    - ARM64: Fix autodetection of fast unaligned memory access when
      using GCC and -mstrict-align is in effect. Previously the
      build systems would incorrectly guess that unaligned access
      is fast, which would result in much slower binaries than
      needed. The fix is a workaround for GCC bug 111555;
      autodetection already worked with Clang.
    - LoongArch: Autodetect if fast unaligned memory access is
      supported. This can improve compression speed by 15 % (but
      not decompression speed).
* Translations:
    - Update the Spanish translation.
    - Add Swedish man page translations.
    - Update Italian, Korean, Romanian, Serbian, and Ukrainian
      man page translations.
