WL#3700: Handler API change: all index search methods - that is,
index_read(), index_read_idx(), index_read_last(), and records_in_range() - instead of 'uint keylen' argument take 'ulonglong keypart_map', a bitmap showing which keyparts are present in the key value. Fallback method is provided for handlers that are lagging behind.
