Currently validation data is shared by using a well known key between
the parachain system pallet and the validate block implementation. This
pr changes this by passing the parachain system directly to the validate
block implementation to make use of it. Besides that, we also store the
validation params in some thread local variable to make it inspectable
by parachain system. This moves the validation of validation data and
validation params to the parachain system pallet directly, instead of
having this hidden inside the validate block implementation.

Fixes: https://github.com/paritytech/cumulus/issues/217

* Move consensus to consensus-common crate

* Move the parachain consensus out of the collator

* Add first relay chain consensus stuff

* Remove some warnings

* Fix more stuff

* Fix collator test

* Change `ParachainConsensus` to take a mutable self

* Make everything compile

* Feedback

* Update Substrate & Polkadot

* Update chainspecs

* Update again to fix test

This renames and moves the `SystemInherentData` into its own crate.
The struct is now called `ParachainInherentData`. Besides moving the
struct, this also moves the code for creating this struct into this crate.

* Move pallets to pallets folder and rename them

* Move genesis file to service

* Rename primitives to primitives-core

* Delete cumulus-runtime

* Move stuff to client folder and rename

* 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

* Block announce validation should use the correct `Validation` result

The error variant is just for internal errors and we need to return
`Failure` always when the other node send us an invalid statement.

* Update network/src/lib.rs

* Complete telemetry for parachain & relaychain

* Update Substrate & Polkadot

This changes the collator to print an error if the block that we can not
find is the genesis block, instead of only logging this as a `debug`
message. This should help people when they have registered the wrong
genesis state on the relay chain.

* Switch to custom `BlockAnnounceData`

Instead of sending a `SignedFullStatement` this switches to a new struct
`BlockAnnounceData` that is being send alongside the block announcement.
The signed full statement contains the candidate commitments, meaning it
could be a full runtime upgrade that we send alongside a block
announcement... To prevent this, we now only send the candidate receipt
and the compact statement.

* Update to latest polkadot

* rename parachain-{upgrade -> system}

* Merge message-broker into parachain-system

* Remove message-broker and clean up

* Update docs

* Test upward messages sending

And also update the relay-sproof-builder so that it allows to set the
relay dispatch queue size for the given parachain.

* Test horizontal message sending

* Remove old inherent definitions

* Replace ValidationData with PersistedValidationData

* Update polkadot

* Missing set_offchain_storage overload.

* right name
