- this would be the first 3.3 release, scripts still needed
cleanup to handle all the changes in 3.3
- support "-alpha1" kinds of designation
- support more versioning information in the headers
- 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
- The sources were in src/calamares but processed and generated
in libcalamares, which is weird at best.
- Generate an "extended" version header.
- Use the extended version in the logger and nowhere else.
- While here, minor coding style cleanups
The overall change here means that after running CMake, only
Logger.cpp needs to be rebuilt (if the extended version has
changed) and not a handful of other files that don't need the
full version number, but do happen to include CalamaresVersion.h
