rebase: move storestatus onto rebaseruntime

rebase: move storestatus onto rebaseruntime

The rebaseruntime class already has the restorestatus function, so let's make it
own the store status function too. This get's rid of a lot of unnecessary
argument passing and will make a future patch cleaner that refactors storestatus
to support transactions.
