  1. blockchain: Add invalidate/reconsider infrastruct. 

    This adds infrastructure to support invalidating arbitrary blocks as if
they had violated a consensus rule as well as reconsidering arbitrary
blocks for validation under the current consensus rules.

It also includes comprehensive tests to ensure proper functionality.

Example use cases this enables:

- Revalidating blocks under new consensus rules
  - Consider the case of old software rejecting blocks due to new
    consensus rules activating on the network and then upgrading to a
    new version that supports the new rules
- Possibility of manually generating snapshots of historical state such
  as live tickets and available utxos
- Manually recovering from unexpected circumstances
- Easier chain reorganization testing
