Track traffic across interface and device restarts and limit consumption to a donation-backed amount.

To increase SSD lifetime persistent storage is only touched every $MaxPerTrafficDiff bytes (currently 100 MB). So tracking can be trivially avoided by frequent router reboot.

Usage

• call traffic_track via cron as often as possible
• call traffic_status to see the different bandwith counters
• call traffic_account_donation to increase the traffic limit after you put the coin in the treasure chest
