Most *partition* module jobs run an operation and turn that into
a JobResult -- ok if it succeeds, and with the report text otherwise.
Factor it out into a separate method that can be used as shorthand.
When creating or editing a new formatted partition, allow
to set a filesystem label (16 chars maximum). Modify
the KPMHelpers to accept it as a new parameter. Partitions
created by default may get a meaningful label too.
- point to main Calamares site in the 'part of' headers instead
of to github (this is the "this file is part of Calamares"
opening line for most files).
- remove boilerplate from all source files, CMake modules and completions,
this is the 3-paragraph summary of the GPL-3.0-or-later, which has
a meaning entirely covered by the SPDX tag.
Introduces a "partitioning service" into libcalamares,
shuffles a bunch of things into it, tries to help out
with settling the system between partitioning actions.
- KDE neon ships a post-3.3.0 KPMCore, with deprecations, but not yet
the KPMCore 4 API, so add another API-version check to handle the
deprecations. Keeps warnings down.
Suggested by aliveafter1000: having a default value, and then
filling in the default in one place it is used and not others,
is weird. Instead of dropping the one use, remove the default
value: partition flags are important enough to be explicit.
