Continue along the same line as the recent patch that made the
Ruby-related config scripts Python packages and make also the
configs/common directory a package.
All affected config scripts are updated (hopefully).
Note that this change makes it apparent that the current organisation
and naming of the config directory and its subdirectories is rather
chaotic. We mix scripts that are directly invoked with scripts that
merely contain convenience functions. While it is not addressed in
this patch we should follow up with a re-organisation of the
config structure, and renaming of some of the packages.
Distributed gem5 is the result of the convergence effort between
multi-gem5 and pd-gem5. It relies on the base multi-gem5 infrastructure
for packet forwarding, synchronisation and checkpointing but combines
those with the elaborated network switch model from pd-gem5.
