Prefer converting int` to uint64 and switch foo.len.uint64 to .len64 (#1375)
* avoid converting from uint64 to int, and where most feasible, int type conversion at all

* .len.uint64 -> .len64

* fix 32-bit compilation

* try keeping state_sim loop variable/bounds as int for 32-bit Azure

* len64 -> lenu64

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).

adopt Result[void, string] in place of some bool return signatures (#1275)
* adopt Result[void, string] in place of some bool return signatures

* string -> cstring to reduce memory allocations; ensure all err() strings are constants, with contextual information from higher-level callers

* logScope usage fixes

* homogenize err() reporting convention

* invalid signature in deposit isn't an error

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..
