Make the CheckpointVerifier handle partial restarts (#736) 
Also put generic bounds on the BlockVerifier struct,
so we get better compilation errors.

teor 334329f38a state: Move block header hashing to block_index 
Only hash block headers in the lowest-level block index code.

This design has a few benefits:
  - failures are obvious, because the hash is not available,
  - get_tip() returns a smaller object,
  - we avoid re-hashing block headers multiple times.

These efficiency changes may be needed to support chain reorganisations,
multiple tips, and heavy query loads.

teor 26a58b23de state: Make Response::Added return the block header hash 
Move block header hashing from zebra-consensus to zebra-state.
Handle zebra-state AddBlock errors in zebra-consensus BlockVerifier.
Add unit tests for BlockVerifier state error handling.

Part of #428.
