At the moment it doesn't really make a difference whether we call

expand_zero_clusters_in_l1() is used when downgrading qcow2 images
from v3 to v2 (compat=0.10). This is one of the functions that needed
more changes to support L2 slices, so this patch extends iotest 061 to
test downgrading a qcow2 image using a smaller slice size.

I'm slightly confused by the fact some previously added functions in
this series are seeing changes. Is this just of an artefact of building
up the TCG API in stages or should the changes be rolled into the
original patches?

Initially int64_t was used, but on PowerPC architecture,
clang doesn't have atomic_*_8 function, so it produces
link time error.
QEMU is working with time as with 64bit value, but by
fact 32 bit is enough with CLOCK_REALTIME. In this case
blocktime will keep only 1200 hours time interval.
