fix #769 The following classes are removed: * handler_type * async_result * async_completion * is_dynamic_buffer * is_const_buffer_sequence * is_mutable_buffer_sequence * handler_alloc Actions Required: * Use BOOST_ASIO_HANDLER_TYPE instead of handler_type * Use BOOST_ASIO_INITFN_RESULT_TYPE instead of async_result * Use boost::asio::async_completion * Use boost::asio::is_dynamic_buffer * Use boost::asio::is_const_buffer_sequence * Use boost::asio::is_mutable_buffer_sequence * boost::asio::associated_allocator_t replaces handler_alloc
