818b8de182 keep track of the compaction serial (index)
it is useful so that:
- we only do slow (but very effective) moving gc every 10 compactions
- we can detect a splitstore v0 upgrade and re-warm up

257423e917 fix view waiting issues with the WaitGroup
We can add after Wait is called, which is problematic with WaitGroups.
This instead uses a mx/cond combo and waits while the count is > 0.
The only downside is that we might needlessly wait for (a bunch) of views
that started while the txn is active, but we can live with that.

759594d01c always return the waitgroup in protectView
so that we preclude the following scenario:
    Start compaction.
    Start view.
    Finish compaction.
    Start compaction.

which would not wait for the view to complete.
