In curl_easy_duphandle, when USE_ARES the ares channel of new easy handle is

I think ares_dup should be used under such circumstance.
Oh indeed. Thanks! This flaw makes an easy handle created with
curl_easy_duphandle() not work correctly, doesn't it?
ares_dup() was not added until c-ares 1.6.0 so it is fairly recent. We need to
add a configure check for it. I'm thinking if we can fix this for earlier
c-ares versions or perhaps if we're better off just raising the requirements.
Thoughts (anyone) ?
