* Revert "Pass number of block under construction via RequestInherentData"
This reverts commit 850fe62cc0dfb04252580c21a985962000e693c8.
That initially looked like the better approach--it spent the time
budget for fetching the block number in the proposer, instead of
the provisioner, and that felt more appropriate--but it turns out
not to be obvious how to get the block number of the block under
construction from within the proposer. The Chain API may be less
ideal, but it should be easier to implement.
* wip: get the block under production from the Chain API
* add ChainApiMessage to AllMessages
* don't break the run loop if a provisionable data channel closes
* clone only those backed candidates which are coherent
* propagate chain_api subsystem through various locations
* add delegated_subsystem! macro to ease delegating subsystems
Unfortunately, it doesn't work right:
```
error[E0446]: private type `CandidateBackingJob` in public interface
--> node/core/backing/src/lib.rs:775:1
|
86 | struct CandidateBackingJob {
| - `CandidateBackingJob` declared as private
...
775 | delegated_subsystem!(CandidateBackingJob as CandidateBackingSubsystem);
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ can't leak private type
```
I'm not sure precisely what's going wrong, here; I suspect the problem is
the use of `$job as JobTrait>::RunArgs` and `::ToJob`; the failure would be
that it's not reifying the types to verify that the actual types are public,
but instead referring to them via `CandidateBackingJob`, which is in fact private;
that privacy is the point.
Going to see if I can generic my way out of this, but we may be headed for a
quick revert here.
* fix delegated_subsystem
The invocation is a bit more verbose than I'd prefer, but it's also
more explicit about what types need to be public. I'll take it as a win.
* add provisioning subsystem; reduce public interface of provisioner
* deny missing docs in provisioner
* refactor core selection per code review suggestion
This is twice as much code when measured by line, but IMO it is
in fact somewhat clearer to read, so overall a win.
Also adds an improved rule for selecting availability bitfields,
which (unlike the previous implementation) guarantees that the
appropriate postconditions hold there.
* fix bad merge double-declaration
* update guide with (hopefully) complete provisioner candidate selection procedure
* clarify candidate selection algorithm
* Revert "clarify candidate selection algorithm"

There were large merge issues with the old bitfield signing PR, so
we're just copying all the work from that onto this and restarting.
Much of the existing work will be discarded because we now have better
tools available, but that's fine.
* start rewriting bitfield signing in terms of the util module

It's not an ideal implementation--we can make it much more concurrent--
but at least it compiles.

* add sanity check to only include valid inherents
* stub: encapsulate block production mechanics instead of copying them
The goal is to end up with something like what's in
validation::block_production::*, which encapsulates
basic block production mechanics. This is a better idea than
just straight-up copying those mechanics.
* partial implementation of propose fn
Doesn't actually compile yet; need to bring in some other
commits to ensure ProvisionerMessage is a thing, and also
figure out how to get the block hash given the current
context.
* fix compilation
* clear a few more compile errors
* finish fn propose
* broken: add timeout to proposal
* add timeout to proposal
* guide: provisioner is responsible for selecting parachain candidates
* implement ProvisionerMessage::RequestInherentData & update fn propose
* impl CreateProposer::init; clean up
* impl std::error::Error for Error
* document error-handling rationale
* cause polkadot-service-new to compile correctly
* Move potentially-blocking call from fn init -> fn propose
This means that we can wrap the delayed call into the same
timeout check used elsewhere.
* document struct Proposer
* extract provisioner data fetch
This satisfies two requirements:
- only applies the timeout to actually fetching the provisioner data,
not to constructing the block after
- simplifies the problem of injecting default data if we could not
get the real provisioner data in time.
