[PATCH] avoid calling casefold_internal if the dn is already casefolded

Can someone review this patch ?

It comes from analysis of indexed ldb_search with scope = one or subtree.
For each entries in the index we will compare the dn in the index to dn 
specified as base for the search. And we keep casefolding the later one 
which is useless and costly.

With a hundreds of entries in the index the cost of cost folding is 
starting to be one of the most important one. With this patch we can 
avoid useless calls.
