imported/implemented boost/serialization/variant now contains code for serialization of boost::variant, boost::variant2 and std::variant. Care has been taken to depend only on the public interfaces of these types. Hence, it is reasonable to hope that the archives are compatible in that one type could be saved and subsequently loaded into a compatible type. Hopefully this will be useful in some way. At a minimum it minimizes code duplication.

squash merge all changes in develop into master
squash merge into next boost release
merge into next boost release
changes made in the hope of eliminated “stable” error for functions previously defined in the header. Moved those function to codecvt_null.cpp

a) fixed up CMake Build so it does everything the B2 Build does. They give the same results.
b) made adjustments so that any code which depends upon serialization depends only upon files in the serialization folder/namespace. This should permit one to add serialization to his library without ending up importing the whole damn world.
* Change __BORLANDC__ to BOOST_BORLANDC, which is defined in Boost config for the Embarcadero non-clang-based compilers.
* More changes of __BORLANDC__ to BOOST_BORLANDC, which is defined in Boost config for the Embarcadero non-clang-based compilers.
* Embarcadero C++ clang-based compilers use chdir instead of _chdir on Windows. This was reported to them as a bug.
* Revert "Embarcadero C++ clang-based compilers use chdir instead of _chdir on Windows. This was reported to them as a bug."
This reverts commit d00a21f736.
* Put back the chdir definition change to exclude Embarcadero clang-based compilers.
