Comment 1 for bug 563829

I've reviewed that code and came up with a much simpler to handle root access. That should make upgrade more robust the root olcAccess is just stuck at the beginning of the olcAccess list. Existing olcAccess from upgrades are still applied as the inserted line ends with "by *break".

I also got ready of the cn=localroot,cn=config mapping which could be exist on systems. It makes the whole thing simpler and more robust.
