Log Message:
mpdecimal: update to 4.0.0.

general
~~~~~~~

    **sync soversion and major_version**

    - The added number formatting feature requires an ABI change, hence the
      increase to SOVERSION=4.

    - Packagers outside of the Linux distributions sometimes use the major
      version number as the equivalent of SOVERSION on their platforms and
      have an incorrect SOVERSION for 2.5.1, which requires SOVERSION=3.

    - While SOVERSION is not required to match the major version number
      (example: glibc), mpdecimal will from now on take the path of least
      resistance and always use SOVERSION=MPD_MAJOR_VERSION.

    - The jump to 4.0.0 should also remind users that a C++ library is
      available.

build/install
~~~~~~~~~~~~~

    **features**

    - Support for out-of-tree build.

    - Support for pkg-config.

    - Unix: support for Loongson.

    - Unix: support for CheriBSD.

    - Compilers: support for icx, icpx, ibm-clang_r, ibm-clang++_r, CompCert,
      clang-cl and emscripten.

    - Windows: support for MSYS2/MinGW.

    - MSVC: the build now uses /O2 /DNDEBUG.

    - MSVC: new arm64/arm32 cross build scripts.

    - AIX: the shared libraries are now installed as versioned objects, e.g.,
      shr4.o, shr4_64.o.

    - New ``./configure`` switches:

      ``--enable-static``: enable/disable the build of the static libraries
      (default: enabled).

      ``--enable-pc``: enable/disable the install of the pkgconfig files
      (default: enabled).

      ``--enable-doc``: enable/disable the install of the documentation
      (default: enabled).

    - New ``./configure`` behavior:

      On multilib platforms like AIX that default to 32-bit the 64-bit build can
      be forced with a single ``./configure MACHINE=uint128`` (ibm-clang, gcc)
      or ``./configure MACHINE=ansi64`` (xlc) rather than explicitly setting
      ``CFLAGS``, ``LDFLAGS``, ``CXXFLAGS`` and ``LDXXFLAGS``.

      Note that on most other (multilib) platforms the default is 64-bit and the
      optimal configuration is chosen by just using ``./configure``.

    - New man pages direct users to the mpdecimal-doc package or the online
      HTML documentation.

    **tests**

    - The C++ tests now automatically skip a small number of bignum tests if
      the std::thread stack size (which cannot be altered) is less than 512K.

      For all other tests a thread stack size of roughly 50K is sufficient.

    - Files in the tests/testdata_dist directory have been significantly
      abbreviated in order to facilitate testing on slower platforms. The
      tests take 5s on a modern x86_64 platform.

      The previous tests have been moved to the separate mpdecimal-testdata
      package (replace tests/testdata_dist with the renamed mpdecimal-testdata
      directory).

    **toolchain issues**

    - AIX: The preferred C/C++ compilers are ibm-clang_r and ibm-clang_r++.
      g++ has sporadic C++11 threading issues that only show up in long running
      programs (or short ones with a sufficient number of repetitions):

         https://gcc.gnu.org/bugzilla/show_bug.cgi?id=98390

      If you only use libmpdec (``--disable-cxx``), gcc and xlc are very stable.

    **changed**

    - The ``--enable-profile`` configure option has been removed due to fragile
      integration with a sequence like ``make && make install``. The new method
      is ``make profile && make install``.

    **removed**

    - The prebuilt HTML documentation is now in the separate mpdecimal-doc
      package, which gives distributions that reject prebuilt documentation
      the option to disregard it and use the new man pages.

libmpdec
~~~~~~~~

    **features**

    - Add the "z" format specifier (coerce negative zeros to positive).

    - In extremely rare cases the transcendental functions (exp, ln, log10) did
      not set the Subnormal/Underflow flags. The reason is that in the case of
      an exponent boundary the Ziv correction loop for correct rounding requires
      very few iterations to arrive at the correctly rounded result, but may
      need many more iterations to arrive at the correct flags.

      In these cases, Subnormal/Underflow is not very informative, so the status
      quo was to skip the extra iterations.

      Version 4.0.0 now specializes exponent boundary cases and uses up to five
      additional iterations to set Subnormal/Underflow. The refactored code has
      no speed penalty on average;  in fact, in the deccheck tests (random tests
      with a bias towards corner cases) it is slightly faster.

      No cases have been found where more than two additional iterations are
      required, but they may exist.

    **reliability fixes**

    - mpd_qset_string_exact(), mpd_qset_i64_exact() and mpd_qset_u64_exact()
      can now be called with a nonzero status.  Previously, the functions
      could return NaN/Invalid_operation in that case.

      This is listed under "reliability fixes" since there is no possible
      scenario under which these functions would legitimately be called with
      a nonzero status.

libmpdec++
~~~~~~~~~~

    **features**

    - Add input validation for Decimal.shiftl(), Decimal.shiftr() and
      Decimal::ln10().
