Description:
------------
I have a script that temporarily stores the headers in a file created by $fp_header = tmpfile().
It worked perfectly until upgrading from 5.2.9.
Now curl_setopt($ch, CURLOPT_WRITEHEADER, $fp_header)
triggers a warning:
  Warning: curl_setopt(): the provided file handle is not writable in /curl.php on line x



Reproduce code:
---------------
<?php
ini_set('display_errors',1); error_reporting(E_ALL | E_STRICT);
$ch = curl_init('http://dk.php.net/');
if ( ! ($fp_header = tmpfile())) { die('File not created'); }
curl_setopt($ch, CURLOPT_WRITEHEADER,		$fp_header);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,	true);
curl_exec($ch);
$http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); echo "HTTP $http_code\n";
curl_close($ch);
echo "Headers ===>\n";
rewind($fp_header); echo stream_get_contents($fp_header);
echo "<=== Headers\n";
rewind($fp_header); ftruncate($fp_header, 0);
fwrite($fp_header, "The file is writeable\n");
echo "My test ===>\n";
rewind($fp_header); echo stream_get_contents($fp_header);
echo "<=== My test\n";
fclose($fp_header);

Expected result:
----------------
Output from PHP 5.2.9 (run from command line):
HTTP 200
Headers ===>
HTTP/1.1 200 OK
