src: add nat persistent and random options
This patch adds more configuration options to the nat expression.
The syntax is as follow:
% nft add rule nat postrouting <snat|dnat> <nat_arguments> [flags]
Flags are: random, persistent, random-fully.
Example:
% nft add rule nat postrouting dnat 1.1.1.1 random,persistent
A requirement is to cache some [recent] copies of kernel headers.
