parser: add permission merging

Browse Source 
By changing the compare function from each rule to use class_rule_t,
instead of perms_rule_t, we temporarily ignore if permissions are
different. If every rule attribute is the same, then the permissions
can be merged. This is done at the perms_rule_t's level.
