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.
