libsndfile: Update to 1.0.31

Version 1.0.31 (2021-01-24)

  * The releaser of libsndfile starting from this version is the libsndfile team
    member @SoapGentoo, see AUTHORS for details.
  * Implement fast SSE2 optimized psf_lrintf() and psf_lrintf() functions to
    improve perfomance when libsndfile is built using Visual C++ (especially)
    and other compilers on x86 and AMD64 platforms. See also description of
    ENABLE_SSE2 CMake option in README.md.
  * Documentation:
    * Move site to new URL: http://libsndfile.github.io/libsndfile/
    * Convert documentation pages from HTML to Markdown
    * Use GitHub's Jekyll static site generator to generate static HTML pages
      for site
    * Fix api.md table error, thanks to @zodf0055980
    * Other docuemntation fixes and updates
  * Change CMake's project name from sndfile to libsndfile as it should be.
  * Change behaviour of ENABLE_STATIC_RUNTIME option. In short:
    * You can use ENABLE_STATIC_RUNTIME for CMake >= 3.15 without error.
    * You can use your our method to set MSVC runtime library flags if none of
      ENABLE_STATIC_RUNTIME and CMAKE_MSVC_RUNTIME_LIBRARY were set.
    Advanced information:
    * If this option is defined (set to ON or OFF), set CMP0091 policy to OLD
      (we handle MSVC runtime library flags using compiler flags), set
      corresponding compiler flags for user.
    * NEW: If this option is not defined, set CMP0091 policy to OLD (we handle
      MSVC runtime library flags using compiler flags), don't touch compiler
      options, allow user to set it manually.
    * NEW: If new CMake option CMAKE_MSVC_RUNTIME_LIBRARY is set, change
      CMP0091 policy to NEW (we handle MSVC runtime library flags using that
      option), don't touch compiler flags.
    * NEW: If both ENABLE_STATIC_RUNTIME and CMAKE_MSVC_RUNTIME_LIBRARY are set,
      terminate configuration with fatal error.
    * For MinGW toolchain this option is experimental. If you enabled it and
      then disabled again, you need to clear CMake cache (delete
      CMakeCache.txt).
  * Make CMake clip test faster.
  * Fix CMake bug with sndio library dependency, thanks to @drhenault.
  * Fix memory leak in wav_read_smpl_chunk() function, credit to OSS-Fuzz.
  * Fix aiff_read_header() memory leak(), credit to OSS-Fuzz.
  * Fix leak in wav_read_header(), credit to OSS-Fuzz.
  * Fix leak in wavlike_read_cart_chunk(), credit to OSS-Fuzz.
  * Fix memory leak in wav_read_acid_chunk(), credit to OSS-Fuzz.
  * Fix memory leak in aiff_read_basc_chunk(), credit to OSS-Fuzz.
  * Fix memory leak in wavlike_read_peak_chunk(), credit to OSS-Fuzz.
  * Fix memory leak in aiff_read_header(), credit to OSS-Fuzz.
  * Fix use of uninitialized value in exif_subchunk_parse(), credit to OSS-Fuzz.
  * Fix use of uninitialized value in endswap_int64_t_array(), credit to
    OSS-Fuzz.
  * Fix up the fuzzer so that it can't under or overseek,
    thanks to Max Dymond <cmeister2@gmail.com>.
  * Fix Autotools configure on macOS, thanks to @tmcguire and @nwh.
  * Exclude repository-configuration from git-archive, thanks to @umlaeute.
  * Use version-script when compiling with clang on Unix with Autotools, thanks
    to @tstellar.
  * Improve handling of SMPL chunks in WAV files, thanks to @zodf0055980.
