Aura consensus for parachains (#371)

* Update polkadot * Migrate all uses of MQC heads to merkle proofs * Mass rename `relay_parent_storage_root` * Restore parachain-system tests * Update polkadot and libp2p swarm for testing * Collapse match into an if let Co-authored-by: Bastian Köcher <bkchr@users.noreply.github.com> * Start with something * Update Substrate & Polkadot * Start to make it compile * Make it compile * Begin with something * Yep * I'm a hacker * Bring back the builder * Make it work in some way * Compile * Parachains use their own "slot" * Adds cumulus-pallet-aura * Wrap AuRa import queue to disable equivocation checking by default * Pass slot duration * Check the seal when validating a block * Adds missing file * Try to make the seal working * Fix it * Some fixes * Bring in the latest features to cleanup the code * Update and make it compile * Improve the import * Start fixing * More work * Fix fix fix * Make everything compile * Small cleanups * Rename and more docs * Docs * Fixes fixes fixes * Update rococo-parachains/src/chain_spec.rs * Update client/consensus/aura/src/lib.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update client/consensus/aura/src/lib.rs Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update primitives/parachain-inherent/Cargo.toml Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com> * Update primitives/parachain-inherent/Cargo.toml * Update primitives/parachain-inherent/Cargo.toml * Update primitives/parachain-inherent/Cargo.toml Co-authored-by: Sergei Shulepov <sergei@parity.io> Co-authored-by: André Silva <123550+andresilva@users.noreply.github.com>
