consistent style in `light_client_sync.nim` (#3450)
Uses consistent formatting in `light_client_sync.nim`, always refers to
fork-dependent light client objects in full qualified notation, moves
`get_safety_threshold` helper function to same location as in the spec.

Support for Gnosis Chain (#3415)
* Support for Gnosis Chain

`make gnosis-chain-build` will build the Nimbus gnosis chain binary,
stored in `build/nimbus_beacon_node_for_gnosis_chain`.

`make gnosis-chain` will connect to the network.

Other changes:

* Restore compilation with -d:has_genesis_detection
* Removed Makefile target related to testnet0 and testnet1
* Added more debug logging for failed peer handshakes
* Report misconfigured builds which try to embed network metadata
that is incompatible with the currently selected const preset.
* Don't bundle network metadata in minimal builds, as they are not compatible

Fix a reward calculation bug affecting Prater epoch 64781 (#3428)
To calculate the deltas correctly, the `process_inactivity_updates` function
must be called before the rewards and penalties processing code in order to
update the `inactivity_scores` field in the state. This would have required
duplicating more logic from the spec in the ncli modules, so I've decided to
pay the price of introducing a run-time copy of the state at each epoch which
eliminates the need to duplicate logic (both for this fix and the previous one).

Other changes:

* Fixes for the read-only mode of the `BeaconChainDb`
* Fix an uint64 underflow in the debug output procedure for printing
  balance deltas
* Allow Bellatrix states in the reward computation helpers

speed up trusted node backfill (#3371)
With these changes, we can backfill about 400-500 slots/sec, which means
a full backfill of mainnet takes about 2-3h.

However, the CPU is not saturated - neither in server nor in client
meaning that somewhere, there's an artificial inefficiency in the
communication - 16 parallel downloads *should* saturate the CPU.

One plasible cause would be "too many async event loop iterations" per
block request, which would introduce multiple "sleep-like" delays along
the way.

I can push the speed up to 800 slots/sec by increasing parallel
downloads even further, but going after the root cause of the slowness
would be better.

* avoid some unnecessary block copies
* double parallel requests

Store finalized block roots in database (3s startup) (#3320)
* Store finalized block roots in database (3s startup)

When the chain has finalized a checkpoint, the history from that point
onwards becomes linear - this is exploited in `.era` files to allow
constant-time by-slot lookups.

In the database, we can do the same by storing finalized block roots in
a simple sparse table indexed by slot, bringing the two representations
closer to each other in terms of conceptual layout and performance.

Doing so has a number of interesting effects:

* mainnet startup time is improved 3-5x (3s on my laptop)
* the _first_ startup might take slightly longer as the new index is
being built - ~10s on the same laptop
* we no longer rely on the beacon block summaries to load the full dag -
this is a lot faster because we no longer have to look up each block by
parent root
* a collateral benefit is that we no longer need to load the full
summaries table into memory - we get the RSS benefits of #3164 without
the CPU hit.

Other random stuff:

* simplify forky block generics
* fix withManyWrites multiple evaluation
* fix validator key cache not being updated properly in chaindag
read-only mode
* drop pre-altair summaries from `kvstore`
* recreate missing summaries from altair+ blocks as well (in case
database has lost some to an involuntary restart)
* print database startup timings in chaindag load log
* avoid allocating superfluos state at startup
* use a recursive sql query to load the summaries of the unfinalized
blocks

Zahary Karadjov 47f1f7ff1a More efficient reward data persistance; Address review comments
The new format is based on compressed CSV files in two channels:

* Detailed per-epoch data
* Aggregated "daily" summaries

The use of append-only CSV file speeds up significantly the epoch
processing speed during data generation. The use of compression
results in smaller storage requirements overall. The use of the
aggregated files has a very minor cost in both CPU and storage,
but leads to near interactive speed for report generation.

Other changes:

- Implemented support for graceful shut downs to avoid corrupting
  the saved files.

- Fixed a memory leak caused by lacking `StateCache` clean up on each
  iteration.

- Addressed review comments

- Moved the rewards and penalties calculation code in a separate module

Required invasive changes to existing modules:

- The `data` field of the `KeyedBlockRef` type is made public to be used
  by the validator rewards monitor's Chain DAG update procedure.

- The `getForkedBlock` procedure from the `blockchain_dag.nim` module
  is made public to be used by the validator rewards monitor's Chain DAG
  update procedure.
