* Tidy up tests
* Increase code coverage
* Remove move special members
* Correct behavior for default constructed iterators
API Changes:
* buffers_adaptor is renamed (was buffers_adapter)
Actions Required:
* Replace buffers_adapter.hpp with buffers_adaptor.hpp, and
replace buffers_adapter with buffers_adaptor. Or, define
BOOST_BEAST_ALLOW_DEPRECATED
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
