Updated patch.

After some discussion with Volker, we decide to shorten the names of
tevent_req_get_private_data() into _tevent_req_callback_data()
and
tevent_req_get_private_state() into _tevent_req_state()

and created tevent_req_callback_data() and tevent_req_state() similar to
tevent_req_create() so that we abort if types do not match.

Simo.
