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()

collect signature production and verificaiton in one place (#1179)
* collect signature production and verificaiton in one place

Signatures are made over data and domain - here we collect all such
activities in one place.

Also:
* security: fix cast-before-range-check
* log block/attestation verification consistently
* run block verification based on `getProposer` in its own history
* clean up some unused stuff

* import

* missing raises

begin removing plain BeaconState versions of state transition functions (#951)
* remove near-duplicate code paths: process_slot(), process_slots(), and state_transition() for BeaconState are now wrappers around the HashedBeaconState versions

* convert tests/test_state_transition.nim to use HashedBeaconState

* convert mocking infrastructure and spec_block/epoch_processing tests to use HashedBeaconBlock, and remove thus unused process_slot*(state: var BeaconState)

avoid state copy in state transition (#930)
In BlockPool, we keep the head state around, so it's trivial to restore
the temporary state there and keep going as if nothing happened.

This solves 3 problems:
* stack space - the state copy on mainnet is huge
* GC scanning - using stack space for state slows down the GC
significantly
* reckless copying - the copy itself takes a long time

In state_sim, we'll do the same and allocate on heap - this helps a
little with GC - without it, the collection of the temporary strings
created with `toHex` while printing the json dominates the trace.

0.11.1 beacon chain spec update (#836)
* initial 0.11.1 spec commit; no test regressions and finalizes in eth2_network_simulation

* with BLS 0.10/0.11 available, stop skipping attester slashing, proposer slashing, and voluntary exist operations fixture tests

* switch param orders to group state.{fork, genesis_validators_root}; bump spec/datatypes spec version for network purposes

* mark attestation construction and broadcast and some minimal/mainnet constants as 0.11.1-compatible; remove phase 1 sharding constants from minimal which don't exist in that preset

[WIP] Fake bls at runtime (#735)
* Initial implementation of runtime bls skipping.

Add libnfuzz skipBLSValidation handling, check that it propagates.

* Rename skipBLSValidation -> skipBlsValidation, start skipStateRootValidation
* Replace skipValidation flags with more granular flags.

Also added skipBlockParentRootValidation flag
Mainly replaced with skipBlsValidation but also StateRoot or
BlockParentRootValidation flags where appropriate.

* Adjust interop test to pass when skipping merkle validation.
* Stop skipping validation for mainchain_monitor.
* Remove comment.
* Also skipMerkleValidation for test_beacon_chain_db.
