In the past buildinfo files where added to enable testing for
reproducible builds. The combination of the three buildinfo files
feeds.buildinfo, config.buildinfo and version.buildinfo allow to
recreate the buildsystem and check if compiled binaries are bit for bit
the same as distributed on official servers.
To support the verification efforts of the reproducible-builds.org team
this patch adds the buildsystem revision to the package index. This way
external feeds all external feeds can be rebuild and verified.
Instead of adding a single file to the Packages folder containing the
revision, the per package storage of revisions allow iterative updates.
Even though the buildbots currently rebuild all packages, it would also
be possible to only rebuild upgraded packages in the future.
To keep the `Packages` small, it is ignored when creating the index.
Tested with buildsystem and SDK on ath79/generic.
