ALF-7260: schema comparator

* replace path/push/pop mechanism as it doesn't work well at reporting where differences/validation errors occur.
* add getParent() to DbObject - so that a path-style identifier can be deduced for a DbObject when needed
* add DbProperty to specify a specific DbObject's property and value -- acts as a schema location pointer
* refactored Result code (need difference result and validation error result)
