* Remove a note about sorting for channel id

* Add missing rustdocs to the configuration

* Clarify and update the invariant for HrmpChannelDigests

* Make the onboarding invariant less sloppy

Namely, introduce `Paras::is_valid_para` (in fact, it already is present
in the implementation) and hook up the invariant to that.

Note that this says "within a session" because I don't want to make it
super strict on the session boundary. The logic on the session boundary
should be extremely careful.

Small clean ups

* DMP: fix the naming of the error

* DMP: add caution about a non-existent recipient

At some point we had aliases for all the substrate crates but at some point we've switched to the full names to avoid confusion. It seems that we missed this instance.

* Improve and unify testing facilities

This improves the testing facilities by making the test client easier to
use. It also removes code that is not required for the test client.
Besides that it also moves the test service and test client under
`node/test`.

* Update Cargo.lock

* Update node/test/client/src/block_builder.rs

Co-authored-by: Andronik Ordian <[email protected]>

* annoying whitespaces

* update guide

Add `CheckValidationOutputs` runtime api and also change the
candidate-validation stuff

* promote ValidationOutputs to global primitives

i.e. move it from node specific primitives to global v1 primitives. This
will be needed when we share it later in the runtime inclusion module

* refactor acceptance checks in the inclusion module

factor out the common code to share it during the block inclusion and
for the forthcoming CheckValidationOutputs runtime api.

Also note that the acceptance criteria was updated to incorporate checks
that exist now in candidate-validation

* plumb the runtime api outside

* extract validation_data from ValidationOutputs

* use runtime-api to check validation outputs

apart from that refactor, update docs and tidy a bit

* Update the maxium code size

This is to fix a test that performs an upgrade.

* Make register/deregister parachain dispatchables

This makes `register_parachain` and `deregister_parachain` of
`Registrar` dispatchables.

Besides that it brings back the functionality of the test node to
register a parachain.

* Remove old service, 3rd try

i.e.
Revert "Revert "Remove Old Service, 2nd try (#1732)" (#1758)"

This reverts commit 9a0f08bf

.

Closes #1757.

We now have some evidence that the polkadot validator was producing
blocks after all; the reason the blocks_constructed metric was 0 was
that as a new metric it hadn't yet been incorporated into that
branch's codebase. See
https://github.com/paritytech/polkadot/issues/1757#issuecomment-700977602

As this PR is based on a newer `master` branch than the previous one,
that should hopefully no longer be an issue.

* paras trait now has an Origin type

* initial work running a two node local net

* use the right incantations so the nodes produce blocks together

* improve internal documentation

* import rococo into chain-spec

* make a few stabs at moving forward

* wip: rococo readme

* remove /service crate

- Move the chain-spec files to node-service
- update sufficient cargo files that polkadot-service-new builds
- not everything else builds yet

* wip: chase down some build errors in polkadot-cli

There's a lot more to go, but some progress has happened.

* make more progress getting polkadot-cli to build

* don't ignore polkadot.json within the res directory

* don't recreate pathbufs

* Prepare Polkadot to be used by Cumulus

This begins to make Polkadot usable from Cumulus.

* Remove old test

This reverts commit 7b8f9ba5bfc286a309df89853ae11facf3277ffb.

* WIP: replace v0 ParachainHost impl with v1 for test runtime

This is necessary because one of the current errors when building
the test service boils down to:

the trait bound `polkadot_test_runtime::RuntimeApiImpl<...>`:
  `polkadot_primitives::v1::ParachainHost<...>` is not satisfied

This is WIP because it appears to be causing some std leakage into
the wasm environment, or something; the compiler is currently
complaining about duplicate definitions of `panic_handler` and `oom`.
Presumably I have to identify all std types (Vec etc) and replace
them with sp_std equivalents.

* fix test runtime build

it wasn't std leakage, after all

* bump westend spec version

* use service-new as service within cli

* to revert: demo that forwarding the test runtime to the real impl blows up

* Revert "to revert: demo that forwarding the test runtime to the real impl blows up"

This reverts commit 68d2f385f378721c7433e3e39133434610cd2a51.

* Revert "Revert "to revert: demo that forwarding the test runtime to the real impl blows up""

This reverts commit 04cb1cbf8873b4429cb9c9fdccb7f4bb137dc720.

Might have just forgotten to disable default features

* More reverts

* MOARE

* plug in the runtime as the generic instantiation

This feels closer to a solution, but it still has problems: in particular,
it's assumed that Runtime implements all appropriate Trait traits,
which this one apparently does not.

* implement necessary traits to get the test runtime compiling

This is almost certainly not correct in some way; it really
looks like I need to mess with the construct_runtime! macro
somehow, to inject the inclusion trait's event type as a Event
variant. Still, better lock down this changeset while it all
compiles.

* add inclusion::Event as variant into Event enum

* implement unimplemented bits in kusama

* implement unimplemented bits in polkadot runtime

* implement unimplemented bits in westend runtime

* migrate client upgrades from master

* update test service with new node changes

* package metadata--that wasn't intended to be removed

* add parachains v1 modules to each runtime

It's not clear what precisely this does, but it's probably the right
thing to do.

* enable cli to opt out of full node features

* adjust rococo chainspec per example
