df: Rewrite virt-df in C.
I have diffed the output from the original virt-df with this
new version, and they agree very closely. Some differences:
- Old virt-df have a divide-by-zero error in cases where the
number of used inodes was 0. New virt-df fixes this.
- New virt-df uses gnulib human_readable library which displays
numbers to 3 significant figures for -h output (old version
used an ad hoc function).
