6a3cbea790 treat Has as an implicit Write 
Rationale: the VM uses the Has check to avoid issuing a duplicate Write in the blockstore.
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.

3a9b7c592d mark from current epoch to boundary epoch when necessary 
this is necessary to avoid wearing clown shoes when the node stays
offline for an extended period of time (more than 1 finality).

Basically it gets quite slow if we do the full 2 finality walk, so we
try to avoid it unless necessary.
The conditions under which a full walk is necessary is if there is a
sync gap (most likely because the node was offline) during which the
tracking of writes is inaccurate because we have not yet delivered the
HeadChange notification.  In this case, it is possible to have
actually hot blocks to be tracked before the boundary and fail to mark
them accordingly.  So when we detect a sync gap, we do the full walk;
if there is no sync gap, we can just use the much faster boundary
epoch walk.

63db9e1633 fix(splitstore): fix a panic on revert-only head changes 
Calling, e.g., `lotus chain sethead` on an ancestor tipset won't apply
any new blocks, it'll just revert a bunch. This will lead to HeadChange
calls with no new blocks to apply.

bba71da401 fix: return buffers after canceling badger operation 
In theory, Delete/Put could fail. If it does, we'll return the buffers
to the pool before we're really done with them.

In practice, this is almost certainly not an issue as badger shouldn't
_use_ the buffer unless we flush. But I feel slightly safer this way.
