ff093fae00 use a missing compactionIndex as an indicator for warmup

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.

da0feb3fa4 dont mark references inline; instad rely on the main compaction thread to do concurrent marking 
The problem is that it is possible that an inline marking might take minutes for some objects
(infrequent, but still possible for state roots and prohibitive if that's a block validation).
So we simply track references continuously and rely on the main compaction thread to trigger
concurrent marking for all references at opportune moments.

Assumption: we can mark references faster than they are created during purge or else we'll
never purge anything.

abdf4a161a explicitly switch marksets for concurrent marking 
this has very noticeable impact in initial marking time; it also allows us
to get rid of the confusing ts monikers.

60dd97c7fc fix potential deadlock in View 
As pointed out by magik, it is possible to deadlock if the view callback performs
a blockstore operation while a Lock is pending.
This fixes the issue by optimistically tracking the reference before actually calling
the underlying View and limiting the scope of the lock.
