Max Reitz 5fee192efd qcow2: Helper for refcount array reallocation 
Add a helper function for reallocating a refcount array, independent of
the refcount order. The newly allocated space is zeroed and the function
handles failed reallocations gracefully.

The helper function will always align the buffer size to a cluster
boundary; if storing the refcounts in such an array in big endian byte
order, this makes it possible to write parts of the array directly as
refcount blocks into the image file.
