"."/[eth2_merkleization, forks, ssz_codec]
rework spec imports (#2779) The spec imports are a mess to work with, so this branch cleans them up a bit to ensure that we avoid generic sandwitches and that importing stuff generally becomes easier. * reexport crypto/digest/presets because these are part of the public symbol set of the rest of the spec types * don't export `merge` types from `base` - this causes circular deps * fix circular deps in `ssz/spec_types` - this is the first step in disentangling ssz from spec * be explicit about phase0 vs altair - longer term, `altair` will become the "natural" type set, then merge and so on, so no point in giving `phase0` special preferential treatment

disentangle eth2 types from the ssz library (#2785) * reorganize ssz dependencies This PR continues the work in https://github.com/status-im/nimbus-eth2/pull/2646, https://github.com/status-im/nimbus-eth2/pull/2779 as well as past issues with serialization and type, to disentangle SSZ from eth2 and at the same time simplify imports and exports with a structured approach. The principal idea here is that when a library wants to introduce SSZ support, they do so via 3 files: * `ssz_codecs` which imports and reexports `codecs` - this covers the basic byte conversions and ensures no overloads get lost * `xxx_merkleization` imports and exports `merkleization` to specialize and get access to `hash_tree_root` and friends * `xxx_ssz_serialization` imports and exports `ssz_serialization` to specialize ssz for a specific library Those that need to interact with SSZ always import the `xxx_` versions of the modules and never `ssz` itself so as to keep imports simple and safe. This is similar to how the REST / JSON-RPC serializers are structured in that someone wanting to serialize spec types to REST-JSON will import `eth2_rest_serialization` and nothing else. * split up ssz into a core library that is independendent of eth2 types * rename `bytes_reader` to `codec` to highlight that it contains coding and decoding of bytes and native ssz types * remove tricky List init overload that causes compile issues * get rid of top-level ssz import * reenable merkleization tests * move some "standard" json serializers to spec * remove `ValidatorIndex` serialization for now * remove test_ssz_merkleization * add tests for over/underlong byte sequences * fix broken seq[byte] test - seq[byte] is not an SSZ type There are a few things this PR doesn't solve: * like #2646 this PR is weak on how to handle root and other dontSerialize fields that "sometimes" should be computed - the same problem appears in REST / JSON-RPC etc * Fix a build problem on macOS * Another way to fix the macOS builds Co-authored-by: Zahary Karadjov <zahary@gmail.com>

## Return the current epoch.
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.

group justified and finalized `Checkpoint` (#3841) The justified and finalized `Checkpoint` are frequently passed around together. This introduces a new `FinalityCheckpoint` data structure that combines them into one. Due to the large usage of this structure in fork choice, also took this opportunity to update fork choice tests to the latest v1.2.0-rc.1 spec. Many additional tests enabled, some need more work, e.g. EL mock blocks. Also implemented `discard_equivocations` which was skipped in #3661, and improved code reuse across fork choice logic while at it.

make LC data fork aware (#4493) In a future fork, light client data will be extended with execution info to support more use cases. To anticipate such an upgrade, introduce `Forky` and `Forked` types, and ready the database schema. Because the mapping of sync committee periods to fork versions is not necessarily unique (fork schedule not in sync with period boundaries), an additional column is added to `period` -> `LightClientUpdate` table.
