Where n is the number of page-table/shadow-index entries, avoid spending O(n^2) time in H5PB_dest(). While we're in H5PB_dest(), mark deleted shadow-index entries as "garbage" and skip the O(n) shadow index-entries copy. Rename shadow index-entry member `moved_to_hdf5_file` to `moved_to_lower_file` while I'm in here---NFCI.
