Currently nbackup backup file contains backup header followed by set of <page_number, page_contents> pairs.
Since ODS 12 we store page number at page header. Therefore there is no need to store page_number before
page contents in backup file. Such change makes IO aligned at page size boundary which should be more efficient
and opens possibility to work with async\unbuffered IO in the future.
