Sets the message body length that this will declare, and sets this's encoding to CONTENT_LENGTH.
You do not normally need to call this; if this is set to use Content-Length encoding, libsoup will automatically set its Content-Length header for you immediately before sending the headers. One situation in which this method is useful is when generating the response to a HEAD request; Calling set_content_length allows you to put the correct content length into the response without needing to waste memory by filling in a response body which won't actually be sent.
