Syncrepl of course *handles* all of those cases. The only issue here is that 
our tests expect the results to be in a specific order, which is obviously an 
invalid requirement in the grand scheme of things.

The syncrepl rename-detection can be improved - we can compare the normalized 
parent DN, separately from the un-normalized RDN. This would eliminate a false 
detection of a move/rename solely due to superior RDNs being mismatched.
