* use ForkedHashedBeaconState in StateData * fix FAR_FUTURE_EPOCH -> slot overflow; almost always use assign() * avoid stack allocation in maybeUpgradeStateToAltair() * create and use dispatch functions for check_attester_slashing(), check_proposer_slashing(), and check_voluntary_exit() * use getStateRoot() instead of various state.data.hbsPhase0.root * remove withStateVars.hashedState(), which doesn't work as a design anymore * introduce spec/datatypes/altair into beacon_chain_db * fix inefficient codegen for getStateField(largeStateField) * state_transition_slots() doesn't either need/use blocks or runtime presets * combine process_slots(HBS)/state_transition_slots(HBS) which differ only in last-slot htr optimization * getStateField(StateData, ...) was replaced by getStateField(ForkedHashedBeaconState, ...) * fix rollback * switch some state_transition(), process_slots, makeTestBlocks(), etc to use ForkedHashedBeaconState * remove state_transition(phase0.HashedBeaconState) * remove process_slots(phase0.HashedBeaconState) * remove state_transition_block(phase0.HashedBeaconState) * remove unused callWithBS(); separate case expression from if statement * switch back from nested-ref-object construction to (ref Foo)(Bar())
