The printing was always only done at the end of osmo_apdu_segment_in(), so let's leave the decision up to the user if he wants to print the state at every iteration or not. We now provide osmo_apdu_dump_context_buf() to the user so he can obtain a string representation of the internal state for logging at any time he requires.
