* Don't just swallow error in dummy-subsystem, but log

* Add target to log.

* Rename ExecutionMode to IsolationStrategy

Execution mode is too generic name and can imply a lot of different
aspects of execution. The notion of isolation better describes the
meant aspect.

And while I am at it, I also renamed mode -> strategy cause it seems a
bit more appropriate, although that is way more subjective.

This adds an integration test for parachains that uses the adder
collator. The test will start two relay chain nodes and one collator and
waits until 4 blocks are build and enacted by the parachain.

* 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.

* Make `CandidateCheckContext` use T::BlockNumber for hrmp_watermark

We need to distribute the PoV after we have seconded it. Other nodes
that will receive our `Secondded` statement and want to validate the
candidate another time will request this PoV from us.

Co-authored-by: Fedor Sakharov <fedor.sakharov@gmail.com>

If a core is freed, we need to make sure it is inserted as free into
availability cores, because we can not be sure that the core is occupied
directly again.

* Make `CandidateHash` a real type

This pr adds a new type `CandidateHash` that is used instead of the
opaque `Hash` type. This helps to ensure on the type system level that
we are passing the correct types.

This pr also fixes wrong usage of `relay_parent` as `candidate_hash`
when communicating with the av storage.

* collation-generation: do not exit early on error

* collation-generation: do not exit on double init

* collator-protocol: do not exit on errors and rename LOG_TARGET

* Update node/network/bitfield-distribution/src/lib.rs

* collation-generation: elevate warn! to error!

* collator-protocol: fix imports

* post merge fix

* fix compilation

Besides that the pr also adds a simple test.

* Do not validate a candidate in candidate selection

The candidate selection subsystem should not validate a candidate, as
this is done by the backing subsystem on a `Second` request. Otherwise
we validate one candidate twice.

* Update candidate-selection.md

* Moare fixes for parachains

- Sending data to a job should always contain a relay parent. Done this
for the provisioner
- Fixed the `select_availability_bitfields` function. It was assuming we
have one core per validator, while we only have one core per parachain.
- Drive by async "rewrite" in proposer

* Make tests compile

* Update primitives/src/v1.rs

* add native logging to check_upward_messages

This doesn't affect the WASM builds, but ensures that native versions
(such as are used for testing) emit diagnostics anytime the
check_upward_messages function exits, which should reduce the pain
of debugging when something goes wrong.
