Implement QueryResult_AutoPtr type which is ACE's reference counted auto_ptr(ACE_Refcounted_Auto_Ptr) for QueryResult pointers.

Use this auto_ptr for every DB queries(except QueryNamedResult yet).

This patch guarantees NO memory leaks from QueryResult pointers.

Thanks to raczman for the idea and for the helping to make this patch.
