Unfortunately, some Webservers (e.g. IIS) do not implement the (F)CGI specifications correctly wrt. chunked uploads (i.e. Transfer-encoding: chunked), but instead pass -1 as CONTENT_LENGTH to the CGI application. However, our (F)CFI SAPIs (i.e. cgi and cgi-fcgi) do not support this. Therefore we try to retrieve the stream size in advance and pass it to `curl_mime_data_cb()` to prevent libcurl from doing chunked uploads. This is basically the same approach that `curl_mime_filedata()` implements.
