Sets the message body length that @hdrs will declare, and sets
@hdrs's encoding to %SOUP_ENCODING_CONTENT_LENGTH.
You do not normally need to call this; if @hdrs 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
soup_message_headers_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.
