BlockId reform (#3176) * BlockId reform Introduce `BlockId` that helps track a root/slot pair - this prepares the codebase for backfilling and handling out-of-dag blocks * move block dag code to separate module * fix finalised state root in REST event stream * fix finalised head computation on head update, when starting from checkpoint * clean up chaindag init * revert `epochAncestor` change in introduced in #3144 that would return an epoch ancestor from the canoncial history instead of the given history, causing `EpochRef` keys to point to the wrong block

time: spring cleaning (#3262) Time in the beacon chain is expressed relative to the genesis time - this PR creates a `beacon_time` module that collects helpers and utilities for dealing the time units - the new module does not deal with actual wall time (that's remains in `beacon_clock`). Collecting the time related stuff in one place makes it easier to find, avoids some circular imports and allows more easily identifying the code actually needs wall time to operate. * move genesis-time-related functionality into `spec/beacon_time` * avoid using `chronos.Duration` for time differences - it does not support negative values (such as when something happens earlier than it should) * saturate conversions between `FAR_FUTURE_XXX`, so as to avoid overflows * fix delay reporting in validator client so it uses the expected deadline of the slot, not "closest wall slot" * simplify looping over the slots of an epoch * `compute_start_slot_at_epoch` -> `start_slot` * `compute_epoch_at_slot` -> `epoch` A follow-up PR will (likely) introduce saturating arithmetic for the time units - this is merely code moves, renames and fixing of small bugs.

Fix missing checkpoint states` (#3225) With the right sequence of events (for example a REST request or a validation), it can happen that the first traversal across a state checkpoint boundary is done without storing that state on disk - this causes problens when replaying states, because now states may be missing from the database. Here, we simply avoid using the caches when advancing a state that will go into the database, ensuring that the information lost during caching always is permanently stored. * fix recursion bug in `isProposed`
