Instead of writing the high-level redo log records MLOG_LIST_END_COPY_CREATED, MLOG_COMP_LIST_END_COPY_CREATED write log for each individual insert of a record. page_copy_rec_list_end_to_created_page(): Remove. This will improve the fill factor of some pages. Adjust some tests accordingly. PageBulk::init(), PageBulk::finish(): Avoid setting bogus limits to PAGE_HEAP_TOP and PAGE_N_DIR_SLOTS. Avoid accessor functions that would enforce these limits before the correct ones are set at the end of PageBulk::finish().
