I made the torture test on test 530 go through. This was actually due to
silly code left from when we switched to let the multi handle "hold" the dns cache when using the multi interface... Of course this only triggered when a certain function call returned error at the correct moment.

Remove support for CURLOPT_FAILONERROR, it has gotten too kludgy and weird

15.6 remove CURLOPT_DNS_USE_GLOBAL_CACHE

Remove support for a global DNS cache. Anything global is silly, and we
