Paul Hauner 619ad106cf Restrict fork choice getters to finalized blocks (#1475) ... ## Issue Addressed - Resolves #1451 ## Proposed Changes - Restricts the `contains_block` and `contains_block` so they only indicate a block is present if it descends from the finalized root. This helps to ensure that fork choice never points to a block that has been pruned from the database. - Resolves #1451 - Before importing a block, double-check that its parent is known and a descendant of the finalized root. - Split a big, monolithic block verification test into smaller tests. ## Additional Notes I suspect there would be a craftier way to do the `is_descendant_of_finalized` check, but we're a bit tight on time now and we can optimize later if it starts showing in benches. ## TODO - [x] Tests		2020-08-14 06:36:38 +00:00
