Paul Hauner b063df5bf9 Cross-compile to vendored x86_84, aarch64 (Raspberry Pi 4) (#1497) 
## Issue Addressed

NA

## Proposed Changes

Adds support for using the [`cross`](https://github.com/rust-embedded/cross) project to produce cross-compiled binaries using Docker images.

Provides quite clean and simple cross-compiles cause all the complexity is hidden in Dockerfiles. It does require you to be in the `docker` group though.

## Details

- Adds shortcut commands to `Makefile`
- Ensures `reqwest` and `discv5` use vendored openssl libs (i.e., static not shared).
- Switches to a [commit](284f705964) of blst that has a renamed C function to avoid a collision with openssl (upstream issue: https://github.com/supranational/blst/issues/21).
- Updates `ring` to the latest satisfiable version, since an earlier version was causing issues with `cross`.
- Off-topic, but adds extra message about Windows support as suggested by Discord user.

## Additional Info

- ~~Blocked on #1495~~
- There are no tests in CI for this yet for a few reasons:
  - I'm hesitant to add more long-running tasks.
  - Short-term bitrot should be avoided since we'll use it each release.
  - In the long term I think it would be good to automate binary creation on a release.
- I observed the binaries increase in size from 50mb to 52mb after these changes.

Overview

Lighthouse is:

  • Fully open-source, licensed under Apache 2.0.
  • Security-focused. Fuzzing has begun and security reviews are underway.
  • Built in Rust, a modern language providing unique safety guarantees and excellent performance (comparable to C++).
  • Funded by various organisations, including Sigma Prime, the Ethereum Foundation, ConsenSys and private individuals.
  • Actively involved in the specification and security analysis of the emerging Ethereum 2.0 specification.

Like all Ethereum 2.0 clients, Lighthouse is a work-in-progress.

Development Status

Current development overview:

  • Specification v0.12.1 implemented, optimized and passing test vectors.
  • Rust-native libp2p with Gossipsub and Discv5.
  • RESTful JSON API via HTTP server.
  • Events via WebSocket.
  • Metrics via Prometheus.

Roadmap

  • April 2019: Inital single-client testnets.
  • September 2019: Inter-operability with other Ethereum 2.0 clients.
  • Q1 2020: lighthouse-0.1.0 release: All major phase 0 features implemented.
  • Q2 2020: Public, multi-client testnet with user-facing functionality.
  • Q2 2020: Third-party security review.
  • Q3 2020: Additional third-party security reviews.
  • Q3 2020: Long-lived, multi-client Beacon Chain testnet
  • Q4 2020: Production Beacon Chain (tentative).

Documentation

The Lighthouse Book contains information for testnet users and developers.

Code documentation is generated via cargo doc and hosted at lighthouse-docs.sigmaprime.io.
