I don't have a IPv6 stack installed now so I can't test it. And my patch only
runs gethostbyname (not getaddrinfo) in a separate thread. I can add it later.
I modelled it after the ares-code, so any bugs are yours :)

The bug I had was my fault really. I used calloc() and compiled with
CURLDEBUG. Only problem is that curl_free() tried to free something it
didn't allocate. Should we add curl_calloc() too or add some magic marker
to the 'struct memdebug' block? calloc() is IMHO much cleaner to use.
