f77e3bc0ad Add maxperf build profile (#3608)
## Proposed Changes

Add a new Cargo compilation profile called `maxperf` which enables more aggressive compiler optimisations at the expense of compilation time.

Some rough initial benchmarks show that this can provide up to a 25% reduction to run time for CPU bound tasks like block processing: https://docs.google.com/spreadsheets/d/15jHuZe7lLHhZq9Nw8kc6EL0Qh_N_YAYqkW2NQ_Afmtk/edit

The numbers in that spreadsheet compare the `consensus-context` branch from #3604 to the same branch compiled with the `maxperf` profile using:

```
PROFILE=maxperf make install-lcli
```

## Additional Info

The downsides of the maxperf profile are:

- It increases compile times substantially, which will particularly impact low-spec hardware. Compiling `lcli` is about 3x slower. Compiling Lighthouse is about 5x slower on my 5950X: 17m 38s rather than 3m 28s.

As a result I think we should not enable this everywhere by default.

- **Option 1**: enable by default for our released binaries. This gives the majority of users the fastest version of `lighthouse` possible, at the expense of slowing down our release CI. Source builds will continue to use the default `release` profile unless users opt-in to `maxperf`.
- **Option 2**: enable by default for source builds. This gives users building from source an edge, but makes them pay for it with compilation time. 

I think I would prefer Option 1. I'll try doing some benchmarking to see how long a maxperf build of Lighthouse would take on GitHub actions.

## Issue Addressed

Make sure gas limit examples in our docs represent sane values.

Thanks @dankrad for raising this in discord.

## Additional Info

We could also consider logging warnings about whether the gas limits configured are sane. Prysm has an open issue for this: https://github.com/prysmaticlabs/prysm/issues/10810

177aef8f1e Builder profit threshold flag (#3534)
## Issue Addressed

Resolves https://github.com/sigp/lighthouse/issues/3517

## Proposed Changes

Adds a `--builder-profit-threshold <wei value>` flag to the BN. If an external payload's value field is less than this value, the local payload will be used. The value of the local payload will not be checked (it can't really be checked until the engine API is updated to support this).

66eca1a882 Refactor op pool for speed and correctness (#3312)
## Proposed Changes

This PR has two aims: to speed up attestation packing in the op pool, and to fix bugs in the verification of attester slashings, proposer slashings and voluntary exits. The changes are bundled into a single database schema upgrade (v12).

Attestation packing is sped up by removing several inefficiencies: 

- No more recalculation of `attesting_indices` during packing.
- No (unnecessary) examination of the `ParticipationFlags`: a bitfield suffices. See `RewardCache`.
- No re-checking of attestation validity during packing: the `AttestationMap` provides attestations which are "correct by construction" (I have checked this using Hydra).
- No SSZ re-serialization for the clunky `AttestationId` type (it can be removed in a future release).

So far the speed-up seems to be roughly 2-10x, from 500ms down to 50-100ms.

Verification of attester slashings, proposer slashings and voluntary exits is fixed by:

- Tracking the `ForkVersion`s that were used to verify each message inside the `SigVerifiedOp`. This allows us to quickly re-verify that they match the head state's opinion of what the `ForkVersion` should be at the epoch(s) relevant to the message.
- Storing the `SigVerifiedOp` on disk rather than the raw operation. This allows us to continue track the fork versions after a reboot.

This is mostly contained in this commit 52bb1840ae5c4356a8fc3a51e5df23ed65ed2c7f.

## Additional Info

The schema upgrade uses the justified state to re-verify attestations and compute `attesting_indices` for them. It will drop any attestations that fail to verify, by the logic that attestations are most valuable in the few slots after they're observed, and are probably stale and useless by the time a node restarts. Exits and proposer slashings and similarly re-verified to obtain `SigVerifiedOp`s.

This PR contains a runtime killswitch `--paranoid-block-proposal` which opts out of all the optimisations in favour of closely verifying every included message. Although I'm quite sure that the optimisations are correct this flag could be useful in the event of an unforeseen emergency.

Finally, you might notice that the `RewardCache` appears quite useless in its current form because it is only updated on the hot-path immediately before proposal. My hope is that in future we can shift calls to `RewardCache::update` into the background, e.g. while performing the state advance. It is also forward-looking to `tree-states` compatibility, where iterating and indexing `state.{previous,current}_epoch_participation` is expensive and needs to be minimised.

1c9ec42dcb More merge doc updates (#3509)
## Proposed Changes

Address a few shortcomings of the book noticed by users:

- Remove description of redundant execution nodes
- Use an Infura eth1 node rather than an eth2 node in the merge migration example
- Add an example of the fee recipient address format (we support addresses without the 0x prefix, but 0x prefixed feels more canonical).
- Clarify that Windows support is no longer beta
- Add a link to the MSRV to the build-from-source instructions

aab4a8d2f2 Update docs for mainnet merge release (#3494)
## Proposed Changes

Update the merge migration docs to encourage updating mainnet configs _now_!

The docs are also updated to recommend _against_ `--suggested-fee-recipient` on the beacon node (https://github.com/sigp/lighthouse/issues/3432).

Additionally the `--help` for the CLI is updated to match with a few small semantic changes:

- `--execution-jwt` is no longer allowed without `--execution-endpoint`. We've ended up without a default for `--execution-endpoint`, so I think that's fine.
- The flags related to the JWT are only allowed if `--execution-jwt` is provided.

92d597ad23 Modularise slasher backend (#3443)
## Proposed Changes

Enable multiple database backends for the slasher, either MDBX (default) or LMDB. The backend can be selected using `--slasher-backend={lmdb,mdbx}`.

## Additional Info

In order to abstract over the two library's different handling of database lifetimes I've used `Box::leak` to give the `Environment` type a `'static` lifetime. This was the only way I could think of using 100% safe code to construct a self-referential struct `SlasherDB`, where the `OpenDatabases` refers to the `Environment`. I think this is OK, as the `Environment` is expected to live for the life of the program, and both database engines leave the database in a consistent state after each write. The memory claimed for memory-mapping will be freed by the OS and appropriately flushed regardless of whether the `Environment` is actually dropped.

We are depending on two `sigp` forks of `libmdbx-rs` and `lmdb-rs`, to give us greater control over MDBX OS support and LMDB's version.

18383a63b2 Tidy eth1/deposit contract logging (#3397)
## Issue Addressed

Fixes an issue identified by @remyroy whereby we were logging a recommendation to use `--eth1-endpoints` on merge-ready setups (when the execution layer was out of sync).

## Proposed Changes

I took the opportunity to clean up the other eth1-related logs, replacing "eth1" by "deposit contract" or "execution" as appropriate.

I've downgraded the severity of the `CRIT` log to `ERRO` and removed most of the recommendation text. The reason being that users lacking an execution endpoint will be informed by the new `WARN Not merge ready` log pre-Bellatrix, or the regular errors from block verification post-Bellatrix.

6c2d8b2262 Builder Specs v0.2.0 (#3134)
## Issue Addressed

https://github.com/sigp/lighthouse/issues/3091

Extends https://github.com/sigp/lighthouse/pull/3062, adding pre-bellatrix block support on blinded endpoints and allowing the normal proposal flow (local payload construction) on blinded endpoints. This resulted in better fallback logic because the VC will not have to switch endpoints on failure in the BN <> Builder API, the BN can just fallback immediately and without repeating block processing that it shouldn't need to. We can also keep VC fallback from the VC<>BN API's blinded endpoint to full endpoint.

## Proposed Changes

- Pre-bellatrix blocks on blinded endpoints
- Add a new `PayloadCache` to the execution layer
- Better fallback-from-builder logic

## Todos

- [x] Remove VC transition logic
- [x] Add logic to only enable builder flow after Merge transition finalization
- [x] Tests
- [x] Fix metrics
- [x] Rustdocs

904dd62524 Strict fee recipient (#3363)
## Issue Addressed

Resolves #3267
Resolves #3156 

## Proposed Changes

- Move the log for fee recipient checks from proposer cache insertion into block proposal so we are directly checking what we get from the EE
- Only log when there is a discrepancy with the local EE, not when using the builder API. In the `builder-api` branch there is an `info` log when there is a discrepancy, I think it is more likely there will be a difference in fee recipient with the builder api because proposer payments might be made via a transaction in the block. Not really sure what patterns will become commong.
- Upgrade the log from a `warn` to an `error` - not actually sure which we want, but I think this is worth an error because the local EE with default transaction ordering I think should pretty much always use the provided fee recipient
- add a `strict-fee-recipient` flag to the VC so we only sign blocks with matching fee recipients. Falls back from the builder API to the local API if there is a discrepancy .

d5e2d98970 Implement feerecipient API for keymanager (#3213)
## Issue Addressed

* #3173 

## Proposed Changes

Moved all `fee_recipient_file` related logic inside the `ValidatorStore` as it makes more sense to have this all together there. I tested this with the validators I have on `mainnet-shadow-fork-5` and everything appeared to work well. Only technicality is that I can't get the method to return `401` when the authorization header is not specified (it returns `400` instead). Fixing this is probably quite difficult given that none of `warp`'s rejections have code `401`.. I don't really think this matters too much though as long as it fails.

f6ec44f0dd Register validator api (#3194)
## Issue Addressed

Lays the groundwork for builder API changes by implementing the beacon-API's new `register_validator` endpoint

## Proposed Changes

- Add a routine in the VC that runs on startup (re-try until success), once per epoch or whenever `suggested_fee_recipient` is updated, signing `ValidatorRegistrationData` and sending it to the BN.
  -  TODO: `gas_limit` config options https://github.com/ethereum/builder-specs/issues/17
-  BN only sends VC registration data to builders on demand, but VC registration data *does update* the BN's prepare proposer cache and send an updated fcU to  a local EE. This is necessary for fee recipient consistency between the blinded and full block flow in the event of fallback.  Having the BN only send registration data to builders on demand gives feedback directly to the VC about relay status. Also, since the BN has no ability to sign these messages anyways (so couldn't refresh them if it wanted), and validator registration is independent of the BN head, I think this approach makes sense. 
- Adds upcoming consensus spec changes for this PR https://github.com/ethereum/consensus-specs/pull/2884
  -  I initially applied the bit mask based on a configured application domain.. but I ended up just hard coding it here instead because that's how it's spec'd in the builder repo. 
  -  Should application mask appear in the api?

375e2b49b3 Conserve disk space by raising default SPRP (#3137)
## Proposed Changes

Increase the default `--slots-per-restore-point` to 8192 for a 4x reduction in freezer DB disk usage.

Existing nodes that use the previous default of 2048 will be left unchanged. Newly synced nodes (with or without checkpoint sync) will use the new 8192 default. 

Long-term we could do away with the freezer DB entirely for validator-only nodes, but this change is much simpler and grants us some extra space in the short term. We can also roll it out gradually across our nodes by purging databases one by one, while keeping the Ansible config the same.

## Additional Info

We ignore a change from 2048 to 8192 if the user hasn't set the 8192 explicitly. We fire a debug log in the case where we do ignore:

```
DEBG Ignoring slots-per-restore-point config in favour of on-disk value, on_disk: 2048, config: 8192

* Add docs for the plethora of available images!
* Unify all the Docker workflows in `docker.yml` (including for tagged releases).

## Additional Info

The `Dockerfile` is no longer used by our Docker Hub builds, as we use `cross` and a generic approach for ARM and x86. There's a new CI job `docker-build-from-source` which tests the `Dockerfile` without publishing anything.

e961ff60b4 Implement standard keystore API (#2736)
## Issue Addressed

Implements the standard key manager API from https://ethereum.github.io/keymanager-APIs/, formerly https://github.com/ethereum/beacon-APIs/pull/151
Related to https://github.com/sigp/lighthouse/issues/2557

## Proposed Changes

- [x] Add all of the new endpoints from the standard API: GET, POST and DELETE.
- [x] Add a `validators.enabled` column to the slashing protection database to support atomic disable + export.
- [x] Add tests for all the common sequential accesses of the API
- [x] Add tests for interactions with remote signer validators
- [x] Add end-to-end tests for migration of validators from one VC to another
- [x] Implement the authentication scheme from the standard (token bearer auth)

## Additional Info

The `enabled` column in the validators SQL database is necessary to prevent a race condition when exporting slashing protection data. Without the slashing protection database having a way of knowing that a key has been disabled, a concurrent request to sign a message could insert a new record into the database. The `delete_concurrent_with_signing` test exercises this code path, and was indeed failing before the `enabled` column was added.

The validator client authentication has been modified from basic auth to bearer auth, with basic auth preserved for backwards compatibility.

9ed92d6e78 Use "release candidate" in book (#2920)
## Issue Addressed

NA

## Proposed Changes

Since we use the `rc` (release candidate) tag in our version strings, it seems consistent if we also use "release candidate" in the book rather than "pre-release".

Notably, Github adds a "pre-release" tag to release when we request. I think it's OK that Github uses that term whilst we consistently use "release candidate". Our docs indicate that the terms are interchangeable. 

## Additional Info

I hope to use the new docs link in the `v2.1.0` release, so it would be nice if we can merge this soon 🙏

## Additional Info

I have checked that linkcheck has succeeded on the book built locally. 👌 

```shell
$ cd book
$ mdbook serve --open
...
2022-01-14 01:13:40 [INFO] (mdbook::book): Book building has started
2022-01-14 01:13:40 [INFO] (mdbook::book): Running the html backend

$ linkcheck http://localhost:3000
Perfect. Checked 4495 links, 80 destination URLs (76 ignored).
```

Also I'll tackle running linkcheck on CI in another pull request.
