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

ssz: move ref support outside (#943)
* ssz: move ref support outside

Instead of allocating ref's inside SSZ, move it to separate helper:

* makes `ref` allocations explicit
* less magic inside SSZ
* `ref` in nim generally means reference whereas SSZ was loading as
value - if a type indeed used references it would get copies instead of
references to a single value on roundtrip which is unexpected

TODO: EF tests would benefit from some refactoring since they all do the
same thing practically..

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.

[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.
