Introduce feature-test macro BOOST_NO_CXX98_RANDOM_SHUFFLE

Browse Source 
The algorithm std::random_shuffle was marked as deprecated in C++14 and is removed from the upcoming C++17 standard. The name itself is still reserved and library implementations may continue to ship it. In this sense, support for std::random_shuffle must be regarded as purely optional and a feature-test macro is required to test for its presence.
