This is the first in a sequence of changes that change the block:: items
to not include Block as a prefix in their name, in accordance with the
Rust API guidelines.

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.
