* TODO:
* - FIXME: do proper transaction history check in #check_transaction_history()
* - SANITY: rename functions/operations to better describe what they do!
* - OPTIMIZE/SIMPLIFY: modify auditordb to return DK when we inquire about deposit/refresh/refund,
* so we can avoid the costly #get_coin_summary with the transaction history building
* (at least during #analyze_coins); the logic may be partially useful in
* #analyze_merchants (but we won't need the cache!)
* - MAJOR: check that aggregation records exist for deposits past payment deadline
* (or that there was a full refund and thus there is no aggregation)
* Conceptual issue: how do we deal with deposits that we already checked
* in the past? => Need a very separate check / pass for this!
* - BEAUTIFY: write reporting logic to output nice report beyond GNUNET_log()
