As well as writing absolute numeric values to the quota file, you
can now also write numbers preceded by a + sign or a - sign, e.g.
* "+30" would increase the quota by 30
* "+-20" would increase the quota by negative 20,
which is the same as decrease by 20
* "-5" would decrease the quota by 5
1. XT_QUOTA_NO_CHANGE should not alter quota to zero ever
2. XT_QUOTA_PACKET should not be set to zero based on skb->len

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.
