Max Reitz bd4b167f84 qcow2: refcount_order parameter for qcow2_create2 
Add a refcount_order parameter to qcow2_create2(), use that value for
the image header and for calculating the size required for
preallocation.

For now, always pass 4.

This addition requires changes to the calculation of the file size for
the "full" and "falloc" preallocation modes. That in turn is a nice
opportunity to add a comment about that calculation not necessarily
being exact (and that being intentional).
