Log Message:
xz: updated to 5.4.2

5.4.2 (2023-03-18)

* All fixes from 5.2.11 that were not included in 5.4.1.

* If xz is built with support for the Capsicum sandbox but running
  in an environment that doesn't support Capsicum, xz now runs
  normally without sandboxing instead of exiting with an error.

* liblzma:

    - Documentation was updated to improve the style, consistency,
      and completeness of the liblzma API headers.

    - The Doxygen-generated HTML documentation for the liblzma API
      header files is now included in the source release and is
      installed as part of "make install". All JavaScript is
      removed to simplify license compliance and to reduce the
      install size.

    - Fixed a minor bug in lzma_str_from_filters() that produced
      too many filters in the output string instead of reporting
      an error if the input array had more than four filters. This
      bug did not affect xz.

* Build systems:

    - autogen.sh now invokes the doxygen tool via the new wrapper
      script doxygen/update-doxygen, unless the command line option
      --no-doxygen is used.

    - Added microlzma_encoder.c and microlzma_decoder.c to the
      VS project files for Windows and to the CMake build. These
      should have been included in 5.3.2alpha.

* Tests:

    - Added a test to the CMake build that was forgotten in the
      previous release.

    - Added and refactored a few tests.

* Translations:

    - Updated the Brazilian Portuguese translation.

    - Added Brazilian Portuguese man page translation.
