* 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

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"
This reverts commit c68a02ac9cf42b3a4a28eb197d38633a40d0e3e6.
* clarify candidate selection algorithm
* update provisioner to implement candidate selection per the guide
* add test that no more than one bitfield is selected per validator
* add test that each selected bitfield corresponds to an occupied core
* add test that more set bits win conflicts
* add macro for specializing runtime requests; specailize all runtime requests
* add tests harness for select_candidates tests
* add first real select_candidates test, fix test_harness
* add mock overseer and test that success is possible
* add test that the candidate selection algorithm picks the right ones
* make candidate selection test somewhat more stringent
