* Propose bumping StringLimit to 64 bytes

The StringLimit of 50 bytes is too short for useful hashes of different protocols:

- When using IPFS, the hash is 46 bytes. With a protocol prefix and type prefix (IPFS vs IPNS) it becomes: `ipfs://ipfs/QmPK1s3pNYLi9ERiq3BDxKa4XosgWwFRQUydHUtz4YgpqB` or 59 bytes.
- On arweave, the hash is 43 bytes. Prefixed with just `arweave://` bumps it up to 53: `arweave://BNttzDav3jHVnNiV7nYbQv-GY0HQ-4XXsdkE5K9ylHQ`.
- On Sia, with 46 char hashes, adding `sia://` as the protocol to use will bump it past 50: `sia://GACjmEWXmYF1N3Rc-PyjN304-8M0zOXHYzAXY9222xkGhA` (52)

As such, we feel that 64 bytes is a reasonable minimum for the `StringLimit`.

* Adds support for checking the timestamp inherent while validating a block

This adds support for checking the timestamp inherent while validating a
block. This will use the relay chain slot number * relay chain slot
duration to calculate a timestamp. This timestamp is used to check the
timestamp in the timestamp inherent.

This is basically a hack that prevents the inclusion of `:code` in the
storage proof. A proper fix requires some changes to the trie crate to
not include nodes that aren't read.

This includes the fix of compilation for macOS platforms.

Instead of using well known keys to communicate information about a

for this.

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

* 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

Follow https://github.com/paritytech/polkadot/pull/2194 to see the
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

* 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
