Pull request description:

  Start transitioning index code away from using internal node types like `CBlockIndex` and `CChain` so index code is less coupled to node code and index code will later be able to stop locking cs_main and sync without having to deal with validationinterface race conditions, and so new indexes are easier to write and can run as plugins or separate processes.
