        Prepare to encode the HTTP message content.
        Parameters:
        headers - the headers
        acceptEncoding - the value of the "Accept-Encoding" header
        Returns:
        the result of preparation, which is composed of the determined target content encoding and a new EmbeddedChannel that encodes the content into the target content encoding. null if acceptEncoding is unsupported or rejected and thus the content should be handled as-is (i.e. no encoding).
