Do not re-use the attribute @IDXVERSION for SAMDB_INDEXING_VERSION
Confusing these two concepts is not a good idea, SAMDB_INDEXING_VERSION refers to
a change in a Samba rule to canonicalise one of our attributes, not the

is at no extra cost.

ldb_tdb: Prepare to handle rename with GUID index by using ltdb_search_base()
This will allow use of a GUID TDB key in the future. While ltdb_search_base()
might be marginally slower than tdb_exists(), no allocation is done for the
attributes or DN, and renmaes are not a very common operation.
This allows a check if the target DN exists even when the direct DN -> key
link is broken.
