[NETFILTER] x_tables: Abstraction layer for {ip,ip6,arp}_tables
This monster-patch tries to do the best job for unifying the data structures and backend interfaces for the three evil clones ip_tables, ip6_tables and arp_tables. In an ideal world we would never have allowed this kind of copy+paste programming... but well, our world isn't (yet?) ideal. o introduce a new x_tables module o {ip,arp,ip6}_tables depend on this x_tables module o registration functions for tables, matches and targets are only wrappers around x_tables provided functions o all matches/targets that are used from ip_tables and ip6_tables are now implemented as xt_FOOBAR.c files and provide module aliases to ipt_FOOBAR and ip6t_FOOBAR o header files for xt_matches are in include/linux/netfilter/, include/linux/netfilter_{ipv4,ipv6} contains compatibility wrappers around the xt_FOOBAR.h headers Based on this patchset we're going to further unify the code, gradually getting rid of all the layer 3 specific assumptions.

- `credit_cap'. The `peak rate' becomes the cost of passing the
- test, `cost'.
-
- `prev' tracks the last packet hit: you gain one credit per jiffy.
- If you get credit balance more than this, the extra credit is
- discarded. Every time the match passes, you lose `cost' credits;
- if you don't have that many, the test fails.
-
- See Alexey's formal explanation in net/sched/sch_tbf.c.
-
- To avoid underflow, we multiply by 128 (ie. you get 128 credits per
- jiffy). Hence a cost of 2^32-1, means one pass per 32768 seconds
