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.

remove disabled incorrect attestation test (#3175)
In #780 a test was disabled that verified that an attestation with
empty `aggregation_bits` completes successfully. The test was never
re-introduced, and as of the current consensus spec v1.1.6, such
attestations are not considered valid, as they fail the check in
`is_valid_indexed_attestation`. This patch fully removes that outdated
test, and moves it to the list of pending invalid attestation tests.

root
* fetch latest block root from state when creating blocks
* harden `get_beacon_proposer_index` against invalid slots and document
* move random spec function tests to `test_spec.nim`
* avoid unnecessary state root computation before block proposal

altair fork handling cleanups (#3050)
* fix stack overflow crash in REST/debug/getStateV2
* introduce `ForkyXxx` for generic type matching of `Xxx` across

around to resolve circular imports
* remove `ForkedBeaconState`, use `ForkedHashedBeaconState` throughout

* fix several cases of states being stored on stack in tests, causing
random failures on some platforms
* remove reading json support from ncli - this should be ported to the
rest json reading instead (doesn't currently work because stack sizes)

reward accounting for altair+ (#2981)
Similar to the existing `RewardInfo`, this PR adds the infrastructure
needed to export epoch processing information from altair+. Because
accounting is done somewhat differently, the PR uses a fork-specific
object to extrct the information in order to make the cost on the spec
side low.

* RewardInfo -> EpochInfo, ForkedEpochInfo
* use array for computing new sync committee
* avoid repeated total active balance computations in block processing
* simplify proposer index check
* simplify epoch transition tests
* pre-compute base increment and reuse in epoch processing, and a few
other small optimizations

This PR introduces the type and does the heavy lifting in terms of
refactoring - the tools that use the accounting will need separate PR:s
(as well as refinements to the exportred information)

always use static keys in tests (#2928)
There are multiple ways how states can be processed during tests. One is
through tests/mocking, the other through tests/xxxutil. Both methods can
create genesis states with a set of deposits from mock validators. The
private keys for those validators are created differently, though. While
tests/mocking generates random keys, testblockutil generates fixed keys.
This is a problem when mixing both tests/mocking and testblockutil in a
single test case, as they assume that the deposits were generated using
the same method. This patch aligns the key generation across tests.

use correct proposer when mocking blocks (#2869)
When creating beacon blocks, the state needs to be advanced to the new
slot to determine the correct proposer index. In #875 a regression got
introduced that removed this logic when mocking blocks. Existing tests
failed to detect this, as they do not make use of the proposer index.
This patch re-introduces the state advancement, fixing the problem.

The mocking framework was limited to chain configurations that do not

Etan Kissling 6826ddb45d remove non-implemented mock genesis arg
The `initGenesisState` function to mock genesis states for testing was
originally introduced with a `genesis_time` parameter in #326. However,
this parameter was never respected and genesis state was always mocked
with `genesis_time` assumed to be 0. Since there is no test overriding
`genesis_time`, the parameter is removed until needed.

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

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

Implement split preset/config support (#2710)
* Implement split preset/config support

This is the initial bulk refactor to introduce runtime config values in
a number of places, somewhat replacing the existing mechanism of loading
network metadata.

It still needs more work, this is the initial refactor that introduces
runtime configuration in some of the places that need it.

The PR changes the way presets and constants work, to match the spec. In
particular, a "preset" now refers to the compile-time configuration
while a "cfg" or "RuntimeConfig" is the dynamic part.

A single binary can support either mainnet or minimal, but not both.
Support for other presets has been removed completely (can be readded,
in case there's need).

There's a number of outstanding tasks:

* `SECONDS_PER_SLOT` still needs fixing
* loading custom runtime configs needs redoing
* checking constants against YAML file

* yeerongpilly support

`build/nimbus_beacon_node --network=yeerongpilly --discv5:no --log-level=DEBUG`

* load fork epoch from config

* fix fork digest sent in status
* nicer error string for request failures
* fix tools

* one more

* fixup

* fixup

* fixup

* use "standard" network definition folder in local testnet

Files are loaded from their standard locations, including genesis etc,
to conform to the format used in the `eth2-networks` repo.

* fix launch scripts, allow unknown config values

* fix base config of rest test

* cleanups

* bundle mainnet config using common loader
* fix spec links and names
* only include supported preset in binary

* drop yeerongpilly, add altair-devnet-0, support boot_enr.yaml
