Introduce close_pack_index to permit replacement

By closing the pack index, a caller can later overwrite the index
with an updated index file, possibly after converting from v1 to
the v2 format.  Because p->index_data is NULL after close, on the
next access the index will be opened again and the other members
will be updated with new data.
