To ensure fast box entries are complete when processed by the
receiving process the tag must be written last. This includes a zero
header for the next fast box entry (in some cases). This commit fixes
two instances where the tag was written too early. In one case, on
32-bit systems it is possible for the tag part of the header to be
written before the size. The second instance is an ordering issue. The
zero header was being written after the fastbox header.
Fixes#5375, #5638
