* Drop buildroot from git repository
Manage buildroot in a separate git repository and use a git submodule
to include it into the HAOS source tree.
This makes it easier to manage changes to buildroot since it can be
managed by git. A buildroot fork repository is being maintained with
the changes we currently have. It makes the buildroot-patches unnecessary
and should make it easier to rebase and upstream changes to buildroot.
* Remove buildroot-patches
Now that buildroot changes are managed in the buildroot fork repository
there is no need to manage patches in a separate directory.
* Initialize git submodule if necessary
* Move build directory to root
This avoids conflict/local modification issues with the buildroot
git submodule.
Support OS releases (tags) with custom dev part (3rd group of the
release number). This allows to create tagged release candidates with
the form 6.0.rc1.
Virtual Disk images are often used on Windows and/or Mac platforms where
xz is not a widely known file ending and also not supported by dafault.
Use zip which is much better known.
Keep using xz for boards since those are not meant to be extracted by
users but directly used in Etcher. Also keep using xz for qcow2, since
qcow2 is mostly used on Linux platforms where xz is available by default
and zip usually needs an extra package.
* Bump dev channel after build
Bump version on dev channel automatically when building a dev branch
pre-release.

* Initial version of release workflow using GitHub Actions
Add release workflow using GitHub Actions to replace the current Azure
DevOps pipeline. Currently the same functionality is implemented. This
uses multiple builds in parallel to make better use of CPU resources.
Remove Azure DevOps pipeline.
* Add GitHub Actions workflow for pull-request checks
Lint Dockerfile and shell scripts when PRs are opened.
* Use multiple runners in parallel
Buildroot has stretches where CPU resources are not fully utilized.
Spawn multiple builds accross builders to increase load. Also sort them
by architecture to maximize ccache hit rate.
* Checkout before validate version
