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 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

* Fix HRMP Location

* Add call to xcm handler

* Complete telemetry for parachain & relaychain

* Update Substrate & 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

* Update polkadot

* Extend cumulus primitives with some relay chain exports

polkadot PR

* collator: collect the state proof

This commit changes cumulus-collator so that it takes the relay chain
state at the relay parent and creates a storage proof that contains all
the required data for PVF.

* parachain-upgrade: use the proofs instead

This change is needed to make cumulus logic to not longer depend on the
transient validation data. As part of this change, in order to preserve
the current behavior `code_upgrade_allowed` now is computed on the
parachain side, rather than provided by polkadot.

Turned out that this requires to know the self parachain id so it was
added where needed.

* message-broker: use relay state to track limits

this should make sending messages safe from accidentally running over
the relay chain limits that were previously unknown.

* Update polkadot

So that `relay_storage_root` is available through `ValidationParams`

* Check `relay_storage_root` matches expected

Check that `relay_storage_root` submitted by the collator matches the
one that we receive in `validate_block` through `ValidationParams`

* Add a missing check for `dmq_mqc_head` while we are at it

* Update polkadot

* Fix tests that use the relay storage root

* Apply suggestions from code review

* Update yeah

* Update spec_version

* Wait for block import in parachain consensus

There was a bug in the parachain consensus that when importing a relay
chain block that sets a new best parachain block, but the required
parachain block was not yet imported. This pr fixes this by waiting for
the block to be imported.

* Finish docs

* Update to latest Substrate & Polkadot

* Update the chain specs

* Update polkadot properly...

* Update chainspecs again...

* Again...

* upgrade to latest polkadot

* ss58 in tests

* format

* removed unused import

* initial mock

* integrate xcm-handler into runtime

* expose xcm send error

* oops

* better comment

* HRMP message ingestion

* Plumb hrmp_watermark to build_collation

* Plumb hrmp_watermark to ValidationResult

* Plumb hrmp outbound messages

* Implement message-broker part of HRMP

* Kill UPWARD_MESSAGES as well

Otherwise, they will get resent each block

* Add sudo versions for easier testing

* Remove the xcmp module

Not useful for the moment

* Doc for HRMP message handler

* Estimate the weight upper bound for on_finalize

* Remove a redundant type annotation

* fix spelling of a method

* Apply suggestions from code review

* Deabbreviate dmp and hrmp in the message ingestion type

* Don't use binary_search since it's broken by a following rotate

Instead use the linear search. We can afford linear search here since
due to limited scalability of HRMP we can only have at most a couple of
dozens of channels.

* Fix the watermark

* Upgdate to latest polkadot & substrate

* Fix code formatting (cargo fmt)

* Fix unit tests

* update cumulus to latest polkadot

* s/Trait/Config

To be more consistent with the new naming.

* Update Cargo.lock

* fix network tests

This is mostly a copy of the predating version with exception of some
renaming and alterations (e.g. the message handler takes an inbound
downward message by value, not by reference).
