Improve HSM ML1 migration volume selection by considering fragmentation

When HSM attempts to migrate a data set to an ML1 volume, it only considers free space available on the volume. Unfortunately, in an environment with large volume sizes (like 1TB EAV's), there can be a lot of free space available on a volume, but ...

z/OS USS using "stat" and "st.st_size" does not give expected, correct value
