* New tools for completion handlers: - wrap_handler provides composed io_service execution guarantees. - bind_handler rebinds arguments to handlers. - shared_handler type-erases any completion handler. - buffer_sequence type-erases templated BufferSequences - abstract_socket replaces Socket - socket_wrapper replaces SocketWrapper - beast::asio placeholders to work with std::bind * Removed obsolete classes and functions - AbstractHandler - ComposedAsyncOperation - SharedFunction - SharedHandler - SharedHandlerAllocator - SharedHandlerPtr - SharedHandlerType - SocketBase - SocketWrapperStrand - wrapHandler * Refactored classes to use new tools - abstract_socket - socket_wrapper - HandshakeDetector - HttpClientType * Miscellanous tidying - socket classes moved to beast::asio namespace - beast asio files provide their own namespace declaration. - Fix IsCallPossible conflicting template parameter name - Use <boost/get_pointer.hpp> for C++11 compatibility. - Remove extraneous include path from build environment.
