aliguori 1987530fe0 qcow2 format: keep 'num_free_bytes', and show it upon 'info blockstats' (Uri Lublin)

'num_free_bytes' is the number of non-allocated bytes below highest-allocation.
It's useful, together with the highest-allocation, to figure out how
fragmented the image is, and how likely it will run out-of-space soon.

For example when the highest allocation is high (almost end-of-disk), but 
many bytes (clusters) are free, and can be re-allocated when neeeded, than
we know it's probably not going to reach end-of-disk-space soon.

Added bookkeeping to block-qcow2.c
Export it using BlockDeviceInfo
Show it upon 'info blockstats' if BlockDeviceInfo exists
