* initial hack in
* finish up
* use notification to pass outgoing paras
* move outgoing paras from notifications
* missing comma
* update guides
* clean up
* 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.
* Rename `relay_storage_root` to `relay_parent_storage_root`
* Guide: Split router module in guide.
Now we have: DMP, UMP and Router module.
* Add a glossary entry for what used to be called Router
* Extract DMP
* Extract UMP
* Extract HRMP
* Switch over to new modules
* Router: goodbye sweet prince
* Link to messaging overview for details.
* Update missed rococo and test runtimes.
* Commit destroyed by rebase changes
* Don't deprecate Router but rather make it a meta-project
