- Jeff Pohlmeyer found out that if you ask libcurl to load a cookiefile (with

CURLOPT_COOKIEFILE), add a cookie (with CURLOPT_COOKIELIST), tell it to
  write the result to a given cookie jar and then never actually call
  curl_easy_perform() - the given file(s) to read was never read but the
  output file was written and thus it caused a "funny" result.

- While doing some tests for the bug above, I noticed that Firefox generates
  large numbers (for the expire time) in the cookies.txt file and libcurl
  didn't treat them properly. Now it does.

 - Added more verbose "warning" messages to the curl client for cases where it
   fails to open/read files etc to help users diagnose why it doesn't do what
