Utility class for COW size calculation
The Linux kernel's dm-snapshot relies on a COW device to keep trace of
all the modified sectors.
The COW device has a precise structure, which allows to compute its
space requirement in advance, as a function of:
- sector size;
- chunk size;
- list of modifications applied to the snapshot device.
Create a class that implements the COW device space occupancy given this
information.
