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.

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.
