Bugs in slapd/schema_init.c:
1. integerNormalize() did not \0-terminate the returned bv_val.
2. integer<Filter/Indexer>() returned the normalized integer as a
   hash key instead of a 4-byte hash of it.  bdb_db_hash() did not
   like that at all.

I fixed #2 by copying caseExactIA5<Filter/Indexer>() to
integer<Filter/Indexer>() and adding integerNormalize() at the
appropriate places.  I don't understand the code, but it tests out
just fine:-)
