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.
