Update to Libp2p to 39.1 (#2448)
* Adjust beacon node timeouts for validator client HTTP requests (#2352)

Resolves #2313

Provide `BeaconNodeHttpClient` with a dedicated `Timeouts` struct.
This will allow granular adjustment of the timeout duration for different calls made from the VC to the BN. These can either be a constant value, or as a ratio of the slot duration.

Improve timeout performance by using these adjusted timeout duration's only whenever a fallback endpoint is available.

Add a CLI flag called `use-long-timeouts` to revert to the old behavior.

Additionally set the default `BeaconNodeHttpClient` timeouts to the be the slot duration of the network, rather than a constant 12 seconds. This will allow it to adjust to different network specifications.

* Use read_recursive locks in database (#2417)

Closes #2245

Replace all calls to `RwLock::read` in the `store` crate with `RwLock::read_recursive`.

* Unfortunately we can't run the deadlock detector on CI because it's pinned to an old Rust 1.51.0 nightly which cannot compile Lighthouse (one of our deps uses `ptr::addr_of!` which is too new). A fun side-project at some point might be to update the deadlock detector.
* The reason I think we haven't seen this deadlock (at all?) in practice is that _writes_ to the database's split point are quite infrequent, and a concurrent write is required to trigger the deadlock. The split point is only written when finalization advances, which is once per epoch (every ~6 minutes), and state reads are also quite sporadic. Perhaps we've just been incredibly lucky, or there's something about the timing of state reads vs database migration that protects us.
* I wrote a few small programs to demo the deadlock, and the effectiveness of the `read_recursive` fix: https://github.com/michaelsproul/relock_deadlock_mvp
* [The docs for `read_recursive`](https://docs.rs/lock_api/0.4.2/lock_api/struct.RwLock.html#method.read_recursive) warn of starvation for writers. I think in order for starvation to occur the database would have to be spammed with so many state reads that it's unable to ever clear them all and find time for a write, in which case migration of states to the freezer would cease. If an attack could be performed to trigger this starvation then it would likely trigger a deadlock in the current code, and I think ceasing migration is preferable to deadlocking in this extreme situation. In practice neither should occur due to protection from spammy peers at the network layer. Nevertheless, it would be prudent to run this change on the testnet nodes to check that it doesn't cause accidental starvation.

* Return more detail when invalid data is found in the DB during startup (#2445)

- Resolves #2444

Adds some more detail to the error message returned when the `BeaconChainBuilder` is unable to access or decode block/state objects during startup.

NA

* Use hardware acceleration for SHA256 (#2426)

Modify the SHA256 implementation in `eth2_hashing` so that it switches between `ring` and `sha2` to take advantage of [x86_64 SHA extensions](https://en.wikipedia.org/wiki/Intel_SHA_extensions). The extensions are available on modern Intel and AMD CPUs, and seem to provide a considerable speed-up: on my Ryzen 5950X it dropped state tree hashing times by about 30% from 35ms to 25ms (on Prater).

The extensions became available in the `sha2` crate [last year](https://www.reddit.com/r/rust/comments/hf2vcx/ann_rustcryptos_sha1_and_sha2_now_support/), and are not available in Ring, which uses a [pure Rust implementation of sha2](https://github.com/briansmith/ring/blob/main/src/digest/sha2.rs). Ring is faster on CPUs that lack the extensions so I've implemented a runtime switch to use `sha2` only when the extensions are available. The runtime switching seems to impose a miniscule penalty (see the benchmarks linked below).

## Issue Addressed

#635 

## Proposed Changes
- Keep attestations that reference a block we have not seen for 30secs before being re processed
- If we do import the block before that time elapses, it is reprocessed in that moment
- The first time it fails, do nothing wrt to gossipsub propagation or peer downscoring. If after being re processed it fails, downscore with a `LowToleranceError` and ignore the message.

b4689e20c6 Altair consensus changes and refactors (#2279)
## Proposed Changes

Implement the consensus changes necessary for the upcoming Altair hard fork.

## Additional Info

This is quite a heavy refactor, with pivotal types like the `BeaconState` and `BeaconBlock` changing from structs to enums. This ripples through the whole codebase with field accesses changing to methods, e.g. `state.slot` => `state.slot()`.

78e5c0c157 Capture a missed VC error (#2436)
## Issue Addressed

Related to #2430, #2394

## Proposed Changes

As per https://github.com/sigp/lighthouse/issues/2430#issuecomment-875323615, ensure that the `ProductionValidatorClient::new` error raises a log and shuts down the VC. Also, I implemened `spawn_ignoring_error`, as per @michaelsproul's suggestion in https://github.com/sigp/lighthouse/pull/2436#issuecomment-876084419.

I got unlucky and CI picked up a [new rustsec vuln](https://rustsec.org/advisories/RUSTSEC-2021-0072). To fix this, I had to update the following crates:

- `tokio`
- `web3`
- `tokio-compat-02`

406e3921d9 Use forwards iterator for state root lookups (#2422)
## Issue Addressed

#2377 

## Proposed Changes

Implement the same code used for block root lookups (from #2376) to state root lookups in order to improve performance and reduce associated memory spikes (e.g. from certain HTTP API requests).

## Additional Changes

- Tests using `rev_iter_state_roots` and `rev_iter_block_roots` have been refactored to use their `forwards` versions instead.
- The `rev_iter_state_roots` and `rev_iter_block_roots` functions are now unused and have been removed.
- The `state_at_slot` function has been changed to use the `forwards` iterator.

## Additional Info

- Some tests still need to be refactored to use their `forwards_iter` versions. These tests start their iteration from a specific beacon state and thus use the `rev_iter_state_roots_from` and `rev_iter_block_roots_from` functions. If they can be refactored, those functions can also be removed.

206486006c Add Lighthouse version and commit hash to Prometheus metrics (#2427)

#2225 

## Proposed Changes

Exposes the version given from the `lighthouse_version` crate to the Prometheus metrics server.

## Additional Info

- This metric appears in both the Beacon Node and Validator Client metrics servers.
- This is the simplest solution. It might be better to include the version and commit hash as separate labels rather than combined, however this would be more involved. Happy to do it that way if this is too cumbersome to use.
- The metric appears as:
```
# HELP lighthouse_info The build of Lighthouse running on the server
# TYPE lighthouse_info gauge
lighthouse_info{version="Lighthouse/v1.4.0-379664a+"} 1

6583ce325b Minify slashing protection interchange data (#2380)
## Issue Addressed

Closes #2354

## Proposed Changes

Add a `minify` method to `slashing_protection::Interchange` that keeps only the maximum-epoch attestation and maximum-slot block for each validator. Specifically, `minify` constructs "synthetic" attestations (with no `signing_root`) containing the maximum source epoch _and_ the maximum target epoch from the input. This is equivalent to the `minify_synth` algorithm that I've formally verified in this repository:

3dc1eb5eb6 Ignore inactive validators in validator monitor (#2396)
## Proposed Changes

A user on Discord (`@ChewsMacRibs`) reported that the validator monitor was logging `WARN Attested to an incorrect head` for their validator while it was awaiting activation.

This PR modifies the monitor so that it ignores inactive validators, by the logic that they are either awaiting activation, or have already exited. Either way, there's no way for an inactive validator to have their attestations included on chain, so no need for the monitor to report on them.

## Additional Info

To reproduce the bug requires registering validator keys manually with `--validator-monitor-pubkeys`. I don't think the bug will present itself with `--validator-monitor-auto`.

98ab00cc52 Handle Geth pre-EIP-155 block sync error condition (#2304)
## Issue Addressed

#2293 

## Proposed Changes

 - Modify the handler for the `eth_chainId` RPC (i.e., `get_chain_id`) to explicitly match against the Geth error string returned for pre-EIP-155 synced Geth nodes
 - ~~Add a new helper function, `rpc_error_msg`, to aid in the above point~~
 - Refactor `response_result` into `response_result_or_error` and patch reliant RPC handlers accordingly (thanks to @pawanjay176)

## Additional Info

Geth, as of Pangaea Expanse (v1.10.0), returns an explicit error when it is not synced past the EIP-155 block (2675000). Previously, Geth simply returned a chain ID of 0 (which was obviously much easier to handle on Lighthouse's part).

## Issue Addressed

NA

## Proposed Changes

I've noticed some of the SigP Prater nodes struggling on v1.4.0-rc.0. I suspect this is due to the changes in #2296. Specifically, the trade-off which lowered the memory footprint whilst increasing runtime on some functions.

Presently, this PR is documenting my testing on Prater.

4a6f2fac81 Only perform malloc tuning for beacon node (#2397)
## Issue Addressed

NA

## Proposed Changes

Only run `configure_memory_alllocator` for the BN process.

I noticed that VC memory usage increases significantly with the new malloc tuning parameters. This was also raised by a user on [r/ethstaker](https://www.reddit.com/r/ethstaker/comments/nr8998/lighthouse_prerelease_v140rc0/h0fnt9l?utm_source=share&utm_medium=web2x&context=3).

There wasn't any issue with memory usage by the VC before we implemented #2296, so I think we were a bit overzealous when we allowed these changes to affect it. This PR allows things that weren't broken to remain unfixed.

93100f221f Make less logs for attn with unknown head (#2395)
## Issue Addressed

NA

## Proposed Changes

I am starting to see a lot of slog-async overflows (i.e., too many logs) on Prater whenever we see attestations for an unknown block. Since these logs are identical (except for peer id) and we expose volume/count of these errors via `metrics::GOSSIP_ATTESTATION_ERRORS_PER_TYPE`, I took the following actions to remove them from `DEBUG` logs:

- Push the "Attestation for unknown block" log to trace.
- Add a debug log in `search_for_block`. In effect, this should serve as a de-duped version of the previous, downgraded log.

f6280aa663 v1.4.0-rc.0 (#2379)
## Issue Addressed

NA

## Proposed Changes

Bump versions.

## Additional Info

This is not exactly the v1.4.0 release described in [Lighthouse Update #36](https://lighthouse.sigmaprime.io/update-36.html).

Whilst it contains:

- Beta Windows support
- A reduction in Eth1 queries
- A reduction in memory footprint

It does not contain:

- Altair
- Doppelganger Protection
- The remote signer

We have decided to release some features early. This is primarily due to the desire to allow users to benefit from the memory saving improvements as soon as possible.

## TODO

- [x] Wait for #2340, #2356 and #2376 to merge and then rebase on `unstable`. 
- [x] Ensure discovery issues are fixed (see #2388)
- [x] Ensure https://github.com/sigp/lighthouse/pull/2382 is merged/removed.
- [x] Ensure https://github.com/sigp/lighthouse/pull/2383 is merged/removed.
- [x] Ensure https://github.com/sigp/lighthouse/pull/2384 is merged/removed.
- [ ] Double-check eth1 cache is carried between boots

d34f922c1d Add early check for RPC block relevancy (#2289)
## Issue Addressed

NA

## Proposed Changes

When observing `jemallocator` heap profiles and Grafana, it became clear that Lighthouse is spending significant RAM/CPU on processing blocks from the RPC. On investigation, it seems that we are loading the parent of the block *before* we check to see if the block is already known. This is a big waste of resources.

This PR adds an additional `check_block_relevancy` call as the first thing we do when we try to process a `SignedBeaconBlock` via the RPC (or other similar methods). Ultimately, `check_block_relevancy` will be called again later in the block processing flow. It's a very light function and I don't think trying to optimize it out is worth the risk of a bad block slipping through. 

Also adds a `New RPC block received` info log when we process a new RPC block. This seems like interesting and infrequent info.

bf4e02e2cc Return a specific error for frozen attn states (#2384)
## Issue Addressed

NA

## Proposed Changes

Return a very specific error when at attestation reads shuffling from a frozen `BeaconState`. Previously, this was returning `MissingBeaconState` which indicates a much more serious issue.

## Additional Info

Since `get_inconsistent_state_for_attestation_verification_only` is only called once in `BeaconChain::with_committee_cache`, it is quite easy to reason about the impact of this change.

ba9c4c5eea Return more detail in Eth1 HTTP errors (#2383)
## Issue Addressed

NA

## Proposed Changes

Whilst investigating #2372, I [learned](https://github.com/sigp/lighthouse/issues/2372#issuecomment-851725049) that the error message returned from some failed Eth1 requests are always `NotReachable`. This makes debugging quite painful.

This PR adds more detail to these errors. For example:

- Bad infura key: `ERRO Failed to update eth1 cache             error: Failed to update Eth1 service: "All fallback errored: https://mainnet.infura.io/ => EndpointError(RequestFailed(\"Response HTTP status was not 200 OK:  401 Unauthorized.\"))", retry_millis: 60000, service: eth1_rpc`
- Unreachable server: `ERRO Failed to update eth1 cache             error: Failed to update Eth1 service: "All fallback errored: http://127.0.0.1:8545/ => EndpointError(RequestFailed(\"Request failed: reqwest::Error { kind: Request, url: Url { scheme: \\\"http\\\", cannot_be_a_base: false, username: \\\"\\\", password: None, host: Some(Ipv4(127.0.0.1)), port: Some(8545), path: \\\"/\\\", query: None, fragment: None }, source: hyper::Error(Connect, ConnectError(\\\"tcp connect error\\\", Os { code: 111, kind: ConnectionRefused, message: \\\"Connection refused\\\" })) }\"))", retry_millis: 60000, service: eth1_rpc`
- Bad server: `ERRO Failed to update eth1 cache             error: Failed to update Eth1 service: "All fallback errored: http://127.0.0.1:8545/ => EndpointError(RequestFailed(\"Response HTTP status was not 200 OK:  501 Not Implemented.\"))", retry_millis: 60000, service: eth1_rpc`
