Currently, all size units are expressed as KiB, MiB or GiB (resp. 2^10,
2^20 or 2^30).
In order to maximize compatibility and consistent results with other
partitioning tools, this commit adds support for sizes expressed as KB,
MB or GB (resp. 10^3, 10^6 or 10^9).
This change won't affect existing users, it simply adds a new option
that wasn't previously handled.

Currently, a number of configuration parsing-related functions and
classes use only `int` type for dealing with integers. Should the user
need a bigger integer value, this would result in an erroneous value
being used (`0`), as the correct value would overflow the 32-bits type.
In order to prevent these overflow, this patch replaces `int` with
`qint64` in the following functions & classes :
* CalamaresUtils::yamlScalarToVariant()
* CalamaresUtils::getInteger
* NamedSuffix
* PartitionSize
This way, sizes or other integer values greater than 2^31 (for signed
types) can be used.

- The sub-directories under libcalamares (e.g. Utils, ..)
all live in namespace CalamaresUtils (well, except for Logger).
The services (e.g. subdirs other than utils/) live in their
own nested namespace, so partitioning should go into
CalamaresUtils::Partition for consistency.
- Clang 8 can detect that there is no need for a return if all
previous paths already return. GCC 8 does not. Clang warns if
the unreachable return is there, GCC errors out if it isn't.
- Introduce a hack NOTREACHED that comments-out on Clang, and
marks as unreachable (but still present) on GCC.
- This might go away with an [[unreachable]] annotation or
similar.
- 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.
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.
