Fork choice fixes (#1350)
* remove cruft

* reenable fork choice and fix several issues

* in addForkChoice_v2, the `.error` field would be accessed even when
Result is ok
* remove workaround for invalid block structure in fork choice
* fix `tmpState` being used recursively in callback, causing state
corruption while processing attestation
* fix block callback being called twice per block
* pass state to callback to avoid unnecessary rewinding

* enable head select, fix another bug

* never use `get` without `isOk`
* log nil blockref in case blockref is nil

* add missing error checking

* use correct epoch when updating attestation message

cache block hash (#1329)
hash_tree_root was turning up when running beacon_node, turns out to be
repeated hash_tree_root invocations - this pr brings them back down to
normal.

this PR caches the root of a block in the SignedBeaconBlock object -
this has the potential downside that even invalid blocks will be hashed
(as part of deserialization) - later, one could imagine delaying this
until checks have passed

there's also some cleanup of the `cat=` logs which were applied randomly
and haphazardly, and to a large degree are duplicated by other
information in the log statements - in particular, topics fulfill the
same role

restore EpochRef and flush statecaches on epoch transitions (#1312)
* restore EpochRef and flush statecaches on epoch transitions

* more targeted cache invalidation

* remove get_empty_per_epoch_cache(); implement simpler but still faster get_beacon_proposer_index()/compute_proposer_index() approach; add some abstraction layer for accessing the shuffled validator indices cache

* reduce integer type conversions

* remove most of rest of integer type conversion in compute_proposer_index()

Restore compilation with custom presets (#1309)
This also assigns precise types to the constants in the minimal
and mainnet presets in order to reduce the chance of compilation
errors when custom presets are used (previously, only the custom
presets have precisely assigned types for the constants).

Dual headed fork choice [Revolution] (#1238)
* Dual headed fork choice

* fix finalizedEpoch not moving

* reduce fork choice verbosity

* Add failing tests due to pruning

* Properly handle duplicate blocks in sync

* test_block_pool also add a test for duplicate blocks

* comments addressing review

* Fix fork choice v2, was missing integrating block proposed

* remove a spurious debug writeStackTrace

* update block_sim

* Use OrderedTable to ensure that we always load parents before children in fork choice

* Load the DAG data in fork choice at init if there is some (can sync witti)

* Cluster of quarantined blocks were not properly added to the fork choice

* Workaround async gcsafe warnings

* Update blockpoool tests

* Do the callback before clearing the quarantine

* Revert OrderedTable, implement topological sort of DAG, allow forkChoice to be initialized from arbitrary finalized heads

* Make it work with latest devel - Altona readyness

* Add a recovery mechanism when forkchoice desyncs with blockpool

* add the current problematic node to the stack

* Fix rebase indentation bug (but still producing invalid block)

* Fix cache at epoch boundaries and lateBlock addition

Trusted blocks (#1227)
* cleanups

* fix ncli state root check flag
* add block dump to ncli_db
* limit ncli_db benchmark length
* tone down finalization logs

* introduce trusted blocks

We only store blocks whose signature we've verified in the database - as
such, there's no need to check it again, and most importantly, no need
to deserialize the signature when loading from database.

50x startup time improvement, 200x block load time improvement.

* fix rewinding when deposits have invalid signature
* speed up ancestor iteration by avoiding copy
* avoid deserializing signatures for trusted data
* load blocks lazily when rewinding (less memory used)

* chronicles workarounds

* document trustedbeaconblock
