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.
