Bug Description: repl. of mod/replace deletes multi-valued attrs
Reviewed by: nkinder (Thanks!)
Branch: HEAD
Fix Description: The server implements a mod/replace operation as a
mod/delete if all values, followed by a mod/add of the new values.  The
mod/delete phase, since it removes all of the values, essentially deletes
the attribute, so it must set the attribute deletion_csn.  This is even
true in the case when you do a mod/replace on an attribute that doesn't yet
exist.  We have to create an empty attribute on the deleted_attrs list with
the deletion_csn set to the csn of the operation.  This preserves the
semantics of the mod/replace operation.
When doing the add phase of the mod/replace, we have to be able to
resurrect attributes and values that may have been deleted by the mod/delete
phase.  We can tell that we need to resurrect a deleted value in
resolve_attribute_state_multi_valued, in the deleted_values loop, because
the deletioncsn will be the same as the update csn, and the
delete_priority flag will be 0.
