Zhe Weng 8ae06462eb system/iptables: Support filter table
Add supports for filter table, usage is same as Linux's iptables, including:
- [!] -p/--protocol
- [!] -s/--source -d/--destination
- [!] -i/--in-interface -o/--out-interface
- [!] --sport/--source-port --dport/--destination-port
- [!] --icmp-type

Examples:
> iptables -P FORWARD DROP
> iptables -I INPUT -i eth0 ! -p icmp -j DROP
> iptables -t filter -A FORWARD -p tcp -s 10.0.1.2/24 -d 10.0.3.4/24 -i eth0 -o eth1 --sport 3000:3200 --dport 123:65535 -j ACCEPT
> iptables -t filter -I FORWARD 2 -p icmp ! -s 123.123.123.123 ! -i eth0 -o eth1 ! --icmp-type 255 -j REJECT

> iptables -L
Chain INPUT (policy ACCEPT)
target        prot  idev  odev  source              destination
DROP         !icmp  eth0  any   anywhere            anywhere

Chain FORWARD (policy DROP)
target        prot  idev  odev  source              destination
ACCEPT        tcp   eth0  eth1  10.0.1.2/24         10.0.3.4/24        tcp spts:3000:3200 dpts:123:65535
REJECT        icmp !eth0  eth1 !123.123.123.123/32  anywhere           icmp !type 255

Chain OUTPUT (policy ACCEPT)
target        prot  idev  odev  source              destination

Note:
- We're dropping dependency of argtable3, since it is difficult to support command like '! -p tcp ! -i eth0'
