Since the new PolicyKit does away with easy checking of authorizations, we get to implement it by ourselves, but that's OK since we can actually use it for a lot more stuff. So add the GetPermissions call which returns the permissions the caller actually has, and a signal informing callers that their permissions might have changed. Hook this all up to PolicyKit so it's useful.
