* @param[out] reserve_balance set to the original reserve balance (at the start of this transaction)
* @param[out] age_ok set to true if no age requirements are present on the reserve
* @param[out] allowed_maximum_age if @e age_ok is false, set to the maximum allowed age when withdrawing from this reserve (client needs to call age-withdraw)
* @param[out] ruuid set to the reserve's UUID (reserves table row)
