- allow multiple ports, protocols, macs, icmp types per rule
- implement "limit" and "limit_burst" options for rules
- implement "extra" option to rules and redirects for passing arbritary flags to iptables
- implement negations for "src_port", "dest_port", "src_dport", "src_mac", "proto" and "icmp_type" options
- allow wildcard (*) "src" and "dest" options in rules to allow specifying "any" source or destination
- validate symbolic icmp-type names against the selected iptables binary
- properly handle forwarded ICMPv6 traffic in the default configuration

Allow a redirect like:
config redirect
option src 'wan'
option dest 'lan'
option src_dport '22001'
option dest_port '22'
option proto 'tcp'
note the absence of the "dest_ip" field, meaning to terminate the connection on the firewall itself.
This patch makes three changes:
(1) moves the conntrack module into the conntrack package (but not any of the conntrack_* helpers).
(2) fixes a bug where the wrong table is used when the "dest_ip" field is absent.
(3) accepts incoming connections on the destination port on the input_ZONE table, but only for DNATted
connections.
In the above example,
ssh -p 22 root@myrouter
would fail from the outside, but:
ssh -p 22001 root@myrouter
would succeed. This is handy if:
(1) you want to avoid ssh probes on your router, or
(2) you want to redirect incoming connections on port 22 to some machine inside your firewall, but
still want to allow firewall access from outside.

- support negations for src_ip, dest_ip, src_dip options in rules and redirects
- add NOTRACK target to rule sections, allows to define fine grained notrack rules
