When the EL connection is interrupted, deposits are once more requested
in chunks of 5000 blocks. This is a problem when the response takes over
a minute to produce and consistently times out as followup requests with
lower chunk sizes may no longer work after a request was canceled, e.g.,
when using Geth with websockets. By keeping track of `blocksPerRequest`
across EL reconnections, it is possible to recover from this by avoiding
to continuously repeat the initial request with the full 5000 blocks.
Also cleans up one more "retry of retry" instance; `DataProviderTimeout`
is a `CatchableError` and already handled by the existing retry logic.
When connection to the EL is lost as part of EL deposits importing, the
targeted block range to sync would reset. This is changed to properly
remember import progress across reconnects.

The use of nested `awaitWithRetries` calls would have
resulted in an unexpected number of retries (3x3).
We now use regular `await` in outer layer to avoid the problem.

The new code has an invariant that the `headMerkleizer` field in
the `Eth1Chain` is always kept in sync with the blocks stored in
the chain.
This invariant is now enforced better by doing the necessary merkleizer updates
in the `Eth1Chain.addBlock` function, in the `Eth1Chain.init` function and in the
`Eth1Chain.reset` function.
When importing blocks with deposits from the EL, the timestamp is never
initialized for them. Therefore, only blocks without deposits (for which
the timestamp is obtained) are considered for `is_candidate_block`.
This is fixed by also importing timestamps for blocks with deposits.
* fix obtaining deposits after connection loss
When an error occurs during Eth1 deposits import, the already imported
blocks are kept while the connection to the EL is re-established.
However, the corresponding merkleizer is not persisted, leading to any
future deposits no longer being properly imported. This is quite common
when syncing a fresh Nimbus instance against an already-synced Geth EL.
Fixed by persisting the head merkleizer together with the blocks.
Adds the `--web3-url` launch argument to `nimbus_light_client` to enable
driving the EL with the optimistic head obtained from LC sync protocol.
This will keep issuing `newPayload` / `forkChoiceUpdated` requests for
new blocks, marking them as optimistic. `ZERO_HASH` is reported as the
finalized block for now.
`m.depositsChain.blocks.len` may change during `startEth1Syncing`. If
that happened, an additional check now ensures that `scratchMerkleizer`
was initialized before attempting to use it.
Other fixes:
* Fix bit rot in the `make prater-dev-deposit` target.
* Correct content-type in the responses of the Nimbus signing node
* Invalid JSON payload was being sent in the web3signer requests
Some upstream repos still need fixes, but this gets us close enough that
style hints can be enabled by default.
In general, "canonical" spellings are preferred even if they violate
nep-1 - this applies in particular to spec-related stuff like
`genesis_validators_root` which appears throughout the codebase.
* 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 resource leak introduced in https://github.com/status-im/nimbus-eth2/pull/3279
* Don't restart the Eth1 syncing proggress from scratch in case of
monitor failures during Eth2 syncing.
* Switch to the primary operator as soon as it is back online.
* Log the web3 credentials in fewer places
Other changes:
The 'web3 test' command has been enhanced to obtain and print more
data regarding the selected provider.
