Provide websocket::stream accept() overloads (API Change):
This adds enough functions to the accept and async_accept overload set to cover all combinations of request, buffers, and error_code parameters. This also fixes a defect where providing a complete Upgrade request when there are additional unprocessed octets remaining in the callers stream buffer could not be furnished to the WebSocket implementation.
