branches/zip: Fix bugs related to the insert buffering of

compressed tablespaces.

btr_page_reorganize_low(): Recompute the insert buffer free bits
for compressed pages belonging to a non-clustered index.

btr_cur_optimistic_insert(): Determine if the page was reorganized by
page_cur_tuple_insert(). Do not attempt to reorganize compressed pages,
because that will be attempted by page_cur_tuple_insert().
