Check a handshake request received from the client. This function doesn't verify that the request is an HTTP/1.1 or higher GET request and doesn't perform ``Host`` and ``Origin`` checks. These controls are usually performed earlier in the HTTP request handling code. They're the responsibility of the caller. Args: headers: Handshake request headers. Returns: ``key`` that must be passed to :func:`build_response`. Raises: InvalidHandshake: If the handshake request is invalid.
