С++03 support was deprecated in 1.85 and now can be removed. This PR clears many of workarounds, which are no longer needed now. * Remove unused workaround macros (many of). * Remove BOOST_STATIC_ASSERT usages. * Minimize Boost::type_traits dependency (in favour of STL's type_traits). Closes https://github.com/boostorg/iterator/pull/82.
