I've modified syncrepl tests so that producer/consumer comparison includes all
operational attributes as well.  This yields some surprises.  For example, after
a modify, the modifiersName is changed into the consumer's rootdn.  This occurs
because the modified entry returned by syncprov contains the same modifiersName
as the consumer's copy, so no modifiersName gets appended to the list of
modifications that's passed to the underlying database.  At this point, the
underlying database adds the missing modify opattrs, thus breaking consistency. 
I've modified syncrepl as to always check if the modify opattrs are present,
and, if absent, pull them off the entry sent by syncprov.  However, in this
case, it's likely that the order of th attributes breaks between the producer
and the consumer, thus causing issues at the next check.  Maybe a better fix
would be to allow syncrepl to instruct the database not to create the missing
modify opattrs.  Comments?
