/**
 * ### Endpoint Interface
 *
 * Transport endpoint components needs to provide:
 *
 * **init**\n
 * `lib::error_code init(transport_con_ptr tcon)`\n
 * init is called by an endpoint once for each newly created connection.
 * It's purpose is to give the transport policy the chance to perform any
 * transport specific initialization that couldn't be done via the default
 * constructor.
 *
 * **is_secure**\n
 * `bool is_secure() const`\n
 * Test whether the transport component of this endpoint is capable of secure
 * connections.
 *
 * **async_connect**\n
 * `void async_connect(transport_con_ptr tcon, uri_ptr location,
 *  connect_handler handler)`\n
 * Initiate a connection to `location` using the given connection `tcon`. `tcon`
 * is a pointer to the transport connection component of the connection. When
 * complete, `handler` should be called with the the connection's
 * `connection_hdl` and any error that occurred.
 *
 * **init_logging**
 * `void init_logging(const lib::shared_ptr<alog_type>& a, const lib::shared_ptr<elog_type>& e)`\n
 * Called once after construction to provide pointers to the endpoint's access
 * and error loggers. These may be stored and used to log messages or ignored.
