We introduce a dependency on GitPython(?) If we do this, it should at least
be mentioned somewhere as a new required dependency. There is also
oeqa.utils.git which could be used (and extended).

I think it would be better to have a distro revision (i.e. the "main
revision" or "revision of the main repository", for example oe-core or
poky) and only list additional layers that are not included in the main
repository.
