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
Streamline lookup with Forky and BeaconBlockFork (then we can do the
same for era)
We use type to avoid conditionals, as fork is often already known at a
"higher" level.
* load blockid before loading block by root - this is needed to map root
to slot and will eventually be done via block summary table for "old"
blocks

* Jenkins: get rid of macOS warnings
We're linking object files with debug info with ones without it. Perfectly justified, from our point of view, but dsymutil complains verbosely about it, with no switch to silence it.
Update several `ncli_db` commands to run in readOnly mode, allowing them
to be used with a running instance - in particular era export.
* export all eras by default
* skip already-exported eras

When initializing backfill sync, the implementation intends to start at
the first unknown slot (`1` before tail). However, an incorrect variable
is passed, and backfill sync actually starts at the tail slot instead.
This patch corrects this by passing the intended variable. The problem
was introduced with the original backfill implementation at #3263.
The added options work in opt-in fashion. If they are not specified,
the server will respond to all requests as if the CORS specification
doesn't exist. This will result in errors in CORS-enabled clients.
Please note that future versions may support more than one allowed
origin. The option names will stay the same, but the user will be
able to repeat them on the command line (similar to other options
such as --web3-url).
To be documented in the guide in a separate PR.
The `SyncManager` has a leftover optional `sleepTime` parameter in
its constructor that used to configure the sync loop polling rate.
This parameter was replaced with a constant in #1602 and is no longer
functional. This patch removes the `sleepTime` leftovers.
#3304 introduced a regression to the sync status string displayed in the
status bar; during the main forward sync, the current slot is no longer
reported and always displays as `0`. This patch corrects the computation
to accurately report the current slot once more.
The `SyncManager` has a leftover optional `maxStatusAge` parameter in
its constructor that used to configure the libp2p `Status` polling rate.
This parameter was replaced with a constant in #1827 and is no longer
functional. This patch removes the `maxStatusAge` leftovers.
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
When node is restarted before backfill has started but after some blocks
have finalized with forward sync, we would not start the backfill.
* also clean up one last `SomeSome`
