The rename allows to avoid forming an infinite recursion in compile time (because of noexcept specification that needs to resolve the unqualified call to swap) or run time (in case if the boost::swap function is the only one suitable for the passed arguments). To avoid the compile-time recursion, removed noexcept specification from boost::swap. The specification is still present in boost::core::invoke_swap. Deprecated boost::swap and associated headers. boost::core::invoke_swap is defined in a new boost/core/invoke_swap.hpp header. Updated docs and tests. Removed tests that check inclusion of deprecated headers. Fixes https://github.com/boostorg/core/issues/148.
