XZ Utils 5.4.6 Stable

Here is an extract from the NEWS file:

5.4.6 (2024-01-26)

    * Fixed a bug involving internal function pointers in liblzma not
      being initialized to NULL. The bug can only be triggered if
      lzma_filters_update() is called on a LZMA1 encoder, so it does
      not affect xz or any application known to us that uses liblzma.

    * xz:

        - Fixed a regression introduced in 5.4.2 that caused encoding
          in the raw format to unnecessarily fail if --suffix was not
          used. For instance, the following command no longer reports
          that --suffix must be used:

              echo foo | xz --format=raw --lzma2 | wc -c

        - Fixed an issue on MinGW-w64 builds that prevented reading
          from or writing to non-terminal character devices like NUL.

    * Added a new test.
