evdns: integrate deferred_response_callback into evdns_request the allocation of the struct deferred_reply_callback can fail. If that happens a program waiting for a callback never gets a callback. The program would asume that it either gets an error or a callback when e.g. calling evdns_base_resolve_ipv6. I did an analysis of the evdns.c code and concluded that struct evdns_request would live until the callback is executed. Based on that conclusion I removed the struct deferred_reply_callback and moved the neccessary fields for data which should be copied from struct request into struct evdns_request. The fields evdns_callback_type user_callback and void *user_pointer are moved into struct evdns_request as it is a more natural place for them to live than struct request.
