686b605112 Pretty-print EIP-3076 tests (#1977)
## Proposed Changes

* Pretty-print the EIP-3076 tests to match https://github.com/eth2-clients/slashing-protection-interchange-tests/pull/4
* Move the `curl` invocation that downloads the tests to the test executor, removing the build script (closes #1982)

20339ade01 Refine and test slashing protection semantics (#1885)
## Issue Addressed

Closes #1873

## Proposed Changes

Fixes the bug in slashing protection import (#1873) by pruning the database upon import.

Also expands the test generator to cover this case and a few others which are under discussion here:

https://ethereum-magicians.org/t/eip-3076-validator-client-interchange-format-slashing-protection/4883

## Additional Info

Depending on the outcome of the discussion on Eth Magicians, we can either wait for consensus before merging, or merge our preferred solution and patch things later.

a171fb8843 check if the slashing protection database is locked before creating keys (#1949)
## Issue Addressed

Closes #1790

## Proposed Changes

Make a new method that creates an empty transaction with `TransactionBehavior::Exclusive` to check whether the slashing protection is locked. Call this method before attempting to create or import new validator keystores.  

## Additional Info

N/A

e9d5bade36 Fixed cross-compiling by replacing wget with curl (#1759)
It looks like the default docker image used by cross doesn't have
wget installed. This causes builds to fail. This can be fixed by
switching to curl.

## Issue Addressed
cross-compiling was broken (at least for build-aarch64)

## Proposed Changes
swap wget for curl

1d278aaa83 Implement slashing protection interchange format (#1544)
## Issue Addressed

Implements support for importing and exporting the slashing protection DB interchange format described here:

https://hackmd.io/@sproul/Bk0Y0qdGD

Also closes #1584 

## Proposed Changes

* [x] Support for serializing and deserializing the format
* [x] Support for importing and exporting Lighthouse's database
* [x] CLI commands to invoke import and export
* [x] Export to minimal format (required when a minimal format has been previously imported)
* [x] Tests for export to minimal (utilising mixed importing and attestation signing?)
* [x] Tests for import/export of complete format, and import of minimal format
* [x] ~~Prevent attestations with sources less than our max source (Danny's suggestion). Required for the fake attestation that we put in for the minimal format to block attestations from source 0.~~
* [x] Add the concept of a "low watermark" for compatibility with the minimal format

Bonus!

* [x] A fix to a potentially nasty bug involving validators getting re-registered each time the validator client ran! Thankfully, the ordering of keys meant that the validator IDs used for attestations and blocks remained stable -- otherwise we could have had some slashings on our hands! 😱
* [x] Tests to confirm that this bug is indeed vanquished

b73c497be2 Support multiple BLS implementations (#1335)
## Issue Addressed

NA

## Proposed Changes

- Refactor the `bls` crate to support multiple BLS "backends" (e.g., milagro, blst, etc).
- Removes some duplicate, unused code in `common/rest_types/src/validator.rs`.
- Removes the old "upgrade legacy keypairs" functionality (these were unencrypted keys that haven't been supported for a few testnets, no one should be using them anymore).

## Additional Info

Most of the files changed are just inconsequential changes to function names.

## TODO

- [x] Optimization levels
- [x] Infinity point: https://github.com/supranational/blst/issues/11
- [x] Ensure milagro *and* blst are tested via CI
- [x] What to do with unsafe code?
- [x] Test infinity point in signature sets
