* End multiplexer stream once one of its inputs end.

Also add test, that we don't panic once a stream is exhausted.

* Don't fuse already fused stream.

* Implement `Debug` manually for CandidateHash

This will make candidate hashes printed consistently without the
`CandidateHash(` and `)` decorations.

* Do not print CompressedPov's guts

It can be overwhelming. Better just use the size.

* Log when candidate is generated

* Print para_id and candidate_hash upon receiving a collation

* Move NetworkBridgeEvent to subsystem::messages.

It is not protocol related at all, it is in fact only part of the
subsystem communication as it gets wrapped into messages of each
subsystem.

* Request/response infrastructure is taking shape.

WIP: Does not compile.

* Multiplexer variant not supported by Rusts type system.

* request_response::request type checks.

* Cleanup.

* Minor fixes for request_response.

* Implement request sending + move multiplexer.

Request multiplexer is moved to bridge, as there the implementation is
more straight forward as we can specialize on `AllMessages` for the
multiplexing target.

Sending of requests is mostly complete, apart from a few `From`
instances. Receiving is also almost done, initializtion needs to be
fixed and the multiplexer needs to be invoked.

* Remove obsolete multiplexer.

* Initialize bridge with multiplexer.

* Finish generic request sending/receiving.

Subsystems are now able to receive and send requests and responses via
the overseer.

* Doc update.

* Fixes.

* Link issue for not yet implemented code.

* Fixes suggested by @ordian

 - thanks!

- start encoding at 0
- don't crash on zero protocols
- don't panic on not yet implemented request handling

* Update node/network/protocol/src/request_response/v1.rs

Use index 0 instead of 1.

* PVD: `block_number`->`relay_parent_number`

* ValidationParams: `relay_chain_height`->`relay_parent_number`

* Expose DMQ MQC hash as a well-known-key

This way the relay storage merkle proofs will be able to obtain the DMQ
MQC hash and we will be able to remove the it from the
PersistedValidationData struct.

* PersistedValidationData: Remove HRMP MQC heads

* PersistedValidationData: Remove `dmq_mqc_head`

* Expose the HRMP ingress channel index as a well-known-key

This way a parachain (PVF and collator) can find all the parachains that
have an outbound channel to the given one. That allows in turn to find
all the inbound channels for the given para.

Having access to that allows the parachain to get the same information
as the hrmp_mqc_heads now provide.

* use proper descriptive generic type names

* cleanup

* Table stores a list of detected misbehavior per authority

* add Table::drain_misbehaviors_for

* WIP: unify misbehavior types; report multiple misbehaviors per validator

Code checks, but tests don't yet pass.

* update drain_misbehaviors: return authority id as well as specific misbehavior

* enable unchecked construction of Signed structs in tests

* remove test-features feature & unnecessary generic

* fix backing tests

This took a while to figure out, because where we'd previously been
passing around `SignedFullStatement`s, we now needed to construct
those on the fly within the test, to take advantage of the signature-
checking in the constructor. That, in turn, necessitated changing the
iterable type of `drain_misbehaviors` to return the validator index,
and passing that validator index along within the misbehavior report.

Once that was sorted, however, it became relatively straightforward:
just needed to add appropriate methods to deconstruct the misbehavior
reports, and then we could construct the signed statements directly.
