Implement: Expired Cookies These following situation, curl removes
cookie(s) from struct CookieInfo if the cookie expired.
- Curl_cookie_add()
- Curl_cookie_getlist()
- cookie_output()
... this also makes sure that the progess callback gets called more
often during TFTP transfers.
Added test 1238 to verify.
