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.

fixes #6125

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.

a888ea0d1f fix: avoid holding a lock while calling the View callback 
Interleaved puts/views could get really slow and there's no real reason
to use view under the covers here because the underlying blockstore is
always a "memstore".

2047a74958 implement blockstore.Union, a union blockstore. 
The union blockstore takes a list of blockstores. It returns the first
satisfying read, and broadcasts writes to all stores.

It can be used for operations that require reading from any two blockstores,
for example WalkSnapshot.

3795cc2bd2 segregate chain and state blockstores. 
This paves the way for better object lifetime management.

Concretely, it makes it possible to:
- have different stores backing chain and state data.
- having the same datastore library, but using different parameters.
- attach different caching layers/policies to each class of data, e.g.
  sizing caches differently.
- specifying different retention policies for chain and state data.

This separation is important because:
- access patterns/frequency of chain and state data are different.
- state is derivable from chain, so one could never expunge the chain
  store, and only retain state objects reachable from the last finality
  in the state store.
