Teach revision walking machinery to walk multiple times sequencially
Previously it was not possible to iterate revisions twice using the revision walking api. We add a reset_revision_walk() which clears the used flags. This allows us to do multiple sequencial revision walks. We add the appropriate calls to the existing submodule machinery doing revision walks. This is done to avoid surprises if future code wants to call these functions more than once during the processes lifetime.
