- 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.
- CC0-1.0 for the uninteresting version-headers
- GPL-3.0-or-later for the services
- add SPDX identifiers to Calamares C++ libraries and application sources
- add SPDX identifiers to Calamares QML (panels and slideshow)
- the `qmldir` is a list of names of things in the directory,
so CC0-1.0 it as "uninteresting"
- QRC files are lists of names of things in the directory,
so CC0-1.0 them as well
This is done to support both Pythonic and Qt style method names, i.e.
both "isNextEnabled" and "is_next_enabled" is ok in a Python module.
Also better documentation in PythonQtViewStep, and stub for
setConfigurationMap.
Finally, proper handling of PythonQtViewStep Python-facing basewidget:
with this change, a call to PQVS::widget() only triggers a widget
relayout if it's necessary, and leaves it alone otherwise.
