src: Implement rule comparison
This patch implements the function: bool nftnl_rule_cmp(const struct nftnl_rule *r1, const struct nftnl_rule *r2) for rule comparison. Expressions within rules need to be compared, so also has been created the function: bool nftnl_expr_cmp(const struct nftnl_expr *e1, const struct nftnl_expr *e2); Also includes all expression comparators.
