[FEATURE] Allow specifying a CURL_IPRESOLVE variant for cURL requests.
This allows specifying an IP resolve method for cURL requests in `GeneralUtility::getUrl`.
That change can prevent weird issues with certain SSL/TLS certificates where this function fails although when specifying the correct [CURL_IPRESOLVE](http://php.net/manual/en/function.curl-setopt.php) type, it does indeed work.
This should also be - and also can - backported to the TYPO3 v6.2 branch.
