vyzo
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.

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.

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.

This means that live objects that would be otherwise written are not actually written, resulting
in the first write epoch being considered the write epoch.
