- Implement the following matches:
	+ condition (v4/v6)
	- connbytes (v4)
	+ connlimit (v4)
	+ connmark (v4)
	+ conntrack (v4)
	+ dst (v6)
	+ frag (v6)
	+ fuzzy (v4/v6)
	+ hbh (v6)
	+ helper (v4)
	+ iprange (v4)
	+ ipv6header (v6)
	+ nth (v4/v6)
	- physdev (v4)
	+ pool (v4)
	+ quota (v4)
	+ random (v4/v6)
	- realm (v4)
	+ recent (v4)
	- record_rpc (v4)
	+ rpc (v4)
	+ rt (v6)
	- sctp (v4)
	+ string (v4)
	- u32 (v4)

- Implement the following targets:
	- BALANCE (v4)
	+ CLASSIFY (v4)
	+ CONNMARK (v4)
	+ IPMARK (v4)
	+ NETLINK (v4)
	+ NETMAP (v4)
	+ POOL (v4)
	+ ROUTE (v4)
	+ SAME (v4)
	+ XOR (v4)

- Port more of the netfilter testsuite test cases to IPTables::IPv4. The
  following should be ported ASAP, as they don't require any special stuff:

	21loop.sh
	56speed.sh
	57badtargmatch.sh
	58ipchainscrash.sh
	59numberproto.sh
	60bignum.sh

  Others can be ported later, once I figure out how to reproduce some of the
  other stuff, like the stuff for using /dev/tap* for simulating real network
  activity for rule testing.

- Include some testing of IPTables::IPv6, now that it's there.
