qemu-io's cvtstr function sometimes will incorrectly omit the
decimal part of the number, and sometimes will incorrectly include
it. This patch fixes both. The former is more serious, and can
be seen in the patches to 027.out and 033.out.
The changes to all other files were scripted with sed, so there were
no "surprises" beyond 027.out and 033.out.

Image formats that grow the image file on demand and are organized into
clusters must handle sub-cluster allocating writes. Such writes touch
a portion of a previously unallocated data cluster. After the image
file is grown with the written data, reads of that cluster should work
as expected:
1. Sectors before the written region are zero.
2. The written region is present and the data is uncorrupted.
3. Sectors after the written region are zero.
