tab Table to sort (in join structure)

IMPLEMENTATION
- If there is an index that can be used, 'tab' is modified to use
this index.
- If no index, create with filesort() an index file that can be used to
retrieve rows in order (should be done with 'read_record').
The sorted data is stored in tab->table and will be freed when calling
free_io_cache(tab->table).
RETURN VALUES
