Many callers pass size_t, which gets silently truncated to uint32_t. Harmless, because all practical sizes are well below 4GiB. Clean it up anyway. Size overflow now fails assertions. Bonus: saves a whole bunch of silly casts. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Blue Swirl <blauwirbel@gmail.com>
