This commit adds an option to xt_quota2 called "no-change". The effect of this option, when used, is that it will skip incrementing or decrementing the quota counter, effectively providing a quota test only. The reason for implementing this is so that I could have a rule check if quota is available for a rule in the PREROUTING tables, without actually decrementing the amount of available quota. I only wanted to decrement the amount of available quota in the FORWARD rule. Otherwise, the first packet of every connection would be counted twice.
