In the event that the target checkpoint of an attestation is for the
previous epoch, and the head state has the same dependent root at that
epoch. The reason being that this guarantees that both seed and active
validator indices are guaranteed to be the same at the checkpoint's
epoch, from the point of view of the attester (even on a different
branch) and the head view.
The head state is guaranteed to have the same shuffling and active
indices if the previous dependent root coincides with the target
checkpoint's in some cases.
* Only use head if it's compatible with target
* Allow blocks from the previous epoch to be viable for checkpoints
* Add feature flag to make it configurable
* fix tests
* @satushh's review
* Manu's nit
* Use fields in logs
* Convert genesis times from seconds to time.Time
* Fixing failed forkchoice tests in a new commit so it doesn't get worse
Fixing failed spectest tests in a new commit so it doesn't get worse
Fixing forkchoice tests, then spectests
* Fixing forkchoice tests, then spectests. Now asking for help...
* Fix TestForkChoice_GetProposerHead
* Fix broken build
* Resolve TODO(preston) items
* Changelog fragment
* Resolve TODO(preston) items again
* Resolve lint issues
* Use consistant field names for sinceSlotStart (no spaces)
* Manu's feedback
* Renamed StartTime -> UnsafeStartTime, marked as deprecated because it doesn't handle overflow scenarios.
Renamed SlotTime -> StartTime
Renamed SlotAt -> At
Handled the error in cases where StartTime was used.
@james-prysm feedback
