Bug description:  curl_read callback returns -1 when needs to return size_t 
(unsigned)

Description:
------------
curl_read, can return -1 when it explicitly states its return size_t. This
causes curl versions >= 7.18.X to fail with the attached code.

Curl stores the callback return value as int, but casts it to a size_t to
do a check. This causes the value to become very large and thus the check
fails when it should not.

I tried to download a snapshot and check that out, but the site appears to
be down.

Reproduce code:
---------------
<?php
$host= 'http://bashcurescancer.com/dump-request-variable.php';
$CR = curl_init();
curl_setopt($CR, CURLOPT_TIMEOUT, 60);
curl_setopt($CR, CURLOPT_URL, $host);
curl_setopt($CR, CURLOPT_POST, 1);
curl_setopt($CR, CURLOPT_FAILONERROR, true);
curl_setopt($CR, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($CR, CURLOPT_SSL_VERIFYPEER, 0);
$body = curl_exec( $CR );
$error = curl_error( $CR );
if( !empty( $error )) {
        print("FAIL: $error\n");
        exit(1);
} else {
        print("PASS: " . trim($body) . "\n");
        curl_close($CR);
        exit(0);
}
?>


Expected result:
----------------
PASS: array (

)

Actual result:
--------------
FAIL: Failed to open/read local data from file/application
