src: Wrap netfilter hooks around human readable strings
This allows to use unique, human readable, hook names for the command line and let the user being unaware of the complex netfilter's hook names and there difference depending on the netfilter family. So: add chain foo bar { type route hook NF_INET_LOCAL_IN 0; } becomes: add chain foo bar { type route hook input 0; } It also fixes then the difference in hook values between families. I.e. ARP family has different values for input, forward and output compared to IPv4, IPv6 or bridge.
