## Proposed Changes
Update to the latest version of the Altair spec, which includes new tests and a tweak to the target sync aggregators.
## Additional Info
This change is _not_ required for the imminent Altair devnet, and is waiting on the merge of #2321 to unstable.

## 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()`.

## Issue Addressed
Closes#1504Closes#1505
Replaces #1703Closes#1707
## Proposed Changes
* Update BLST and Milagro to versions compatible with BLSv4 spec
* Update Lighthouse to spec v1.0.0-rc.0, and update EF test vectors
* Use the v1.0.0 constants for `MainnetEthSpec`.
* Rename `InteropEthSpec` -> `V012LegacyEthSpec`
* Change all constants to suit the mainnet `v0.12.3` specification (i.e., Medalla).
* Deprecate the `--spec` flag for the `lighthouse` binary
* This value is now obtained from the `config_name` field of the `YamlConfig`.
* Built in testnet YAML files have been updated.
* Ignore the `--spec` value, if supplied, log a warning that it will be deprecated
* `lcli` still has the spec flag, that's fine because it's dev tooling.
* Remove the `E: EthSpec` from `YamlConfig`
* This means we need to deser the genesis `BeaconState` on-demand, but this is fine.
* Swap the old "minimal", "mainnet" strings over to the new `EthSpecId` enum.
* Always require a `CONFIG_NAME` field in `YamlConfig` (it used to have a default).
## Additional Info
Lots of breaking changes, do not merge! ~~We will likely need a Lighthouse v0.4.0 branch, and possibly a long-term v0.3.0 branch to keep Medalla alive~~.

## Proposed Changes
Update test vectors for v0.12.3, and introduced configurable `proportional_slashing_multiplier`.
Also makes `YamlConfig` a bit safer by making every field access in `apply_to_chain_spec` explicit, and removing the `#[serde(default)]` attribute, which would instantiate missing fields to type defaults! Risky!
Update the EF test vectors to v0.12.2 so that they include the new finality tests. Also, correct a typo that caused the epoch processing final update tests not to run on the minimal spec.
* Update state processing for v0.12
* Fix EF test runners for v0.12
* Fix some tests
* Fix broken attestation verification test
* More test fixes
* Fix typo found in review
