OSBuild - Build-Pipelines for Operating System Artifacts

CHANGES WITH 11:

    * Drop support for legacy input: passing in non-manifest style
      pipelines is now not supported anymore.

    * Support for specifying an UUID for partitions when using the GPT
      partition layout was added to the org.osbuild.qemu assembler.

    * Fix a crash in the case the assembler failed, which was caused by
      cleanup up the object while the object was still being written to.

    * Delay the cleanup of the build tree to after the error checking
      since in the error case there is nothing to clean up and trying
      to do so will lead to crash.

    * `objectstore.Object` now directly cleans its working tree up, in
      contrast to relying on the implicit cleanup of `TemporaryDirectory`.
      One advantage of this is that the custom cleanup code can handle
      immutable directories, which Python 3 fails to clean up.

    * Drop custom `os-release` creation from the RHEL 8.2 runner. The
      issue that made this neccessary got fixed upstream.

    * Ensure the build tree is always being built even if there are no
      stages specified.

    * spec file: Do no generate dependencies for the internal files and
      add NEWS.md to the documentation section.

    * The Fedora 30 based aarch64 example was fixed and now builds again.

CHANGES WITH 10:

    * A new man-page `osbuild-manifest(5)` is available, which describes
      the input format of the JSON manifest that `osbuild` expects.

    * Man-pages can now be built via `make man`. This supports `SRCDIR` and
      `BUILDDIR` variables to build out-of-tree.

    * Temporary objects in the object-store are now created in
      `.osbuild/tmp/`, rather than in the top-level directory. This should
      help cleaning up temporary objects after a crash. If no osbuild
      process is running, the `tmp/` subdirectory should not exist.

    * The final stage of a build-pipeline is no longer automatically
      committed. You must pass checkpoints via `--checkpoint` to commit
      anything to the store.

    * Improve curl timeout handling. This should improve osbuild behavior
      with slow or bad mirrors and make sure operations are retried
      correctly, or time-out if no progress is made.

CHANGES WITH 9:

    * The last pipeline stage is no longer automatically committed to the
      store. This used to be a special case to make things work, but it has
      now been properly fixed.
      From now on, if you want a stage committed to the store, you need to
      pass a `--checkpoint` option for the stage.

    * The runner for the host system is now auto-detected. The
      `runners/org.osbuild.default` symlink is now longer required (nor
      supported).

    * A generic runner named `org.osbuild.linux` was added. This runner
      uses the default value of `ID` in `/etc/os-release`. That is, if the
      local OS cannot be detected, or if no `os-release` file is provided,
      this is the fallback runner that is used.
      This runner only performs the bare minimum of initialization. It is
      enough to run the most basic stages on all systems we tested.

    * On Archlinux, the generic runner will now be used.

    * A new runner for RHEL-8.1 is available.

    * The JSON input to `osbuild` is now a monolithic manifest format which
      contains all build information. For now, this means the input
      manifest can contain a `pipeline:` key with the pipeline definition,
      as well as a `sources:` key with external source definitions
      previously passed via `--sources`.
      The old input format is still supported, but will be dropped in the
      next release.

    * The osbuild sources now come with a man-page `osbuild(1)`. Further
      pages will follow in the future.
