Shows, how much data qcow2 allocates in underlying file. This should
be helpful on non-sparse file systems, when qemu-img info "disk size"
doesn't provide this information.

Hi all.
Here is an allocated-size feature for qemu-img info.
I'm not a fan of loading all L2 tables (can take some time) for
'qemu-img info' (which should be very quick). Why isn't the qemu-img
check output good enough?

$ ./qemu-img check /tmp/test.qcow2
No errors were found on the image.
16164/491520 = 3.29% allocated, 11.98% fragmented, 0.00% compressed clusters
Image end offset: 1060044800
$ ./qemu-img check --output=json /tmp/test.qcow2
{
"image-end-offset": 1060044800,

"check-errors": 0,
