- Although None will be filtered out already by unitsComparable(),
include it in the switch to avoid a warning .. then we can
drop the post-switch return since the switch covers all possible
values of the enum.
- Use unitsComparable where applicable
- Use SizeUnit instead of unit_t -- since this is a template
specialization, we have the more meaningful type name to
use, instead of the generic one.
- Not all kinds of units are comparable. Introduce a method
in PartitionSize to check for comparability (this could
also be a free method, but seems more tidy here because it
is specifically about comparing in the context of partition sizes).
Using PartUtils::PartSize as reference, this commit creates a new
PartitionSize class in libcalamares, which will then be used in every
module needing such a class.
