Instead of pushing the cmp logic for rule merging into each rule class make it the default behavior for the perms_rule_t parent class. Also save off the original perms for the merged rule. For classes that don't want perms merging add an alternate dedup_perms_rule_t clase. Signed-off-by: John Johansen <john.johansen@canonical.com>
