* Remove Sudo

NOTE: To ensure minimal index changes to pre-existing pallet deployments,
this is done with a "swap_remove" style; the previous last pallet
(Purchase), which is hitherto unused, has been shifted into the old index
of Sudo.

* Initial check_runtime.sh redux

* Skip further checks if no change to runtime

* remove polkadot-master reference

* Fix issues found during review :)

* replace static common dir with common_dirs array

* Add subsystem-util crate.

Start by moving the JobCanceler here.

* copy utility functions for requesting runtime data; generalize

* convert subsystem-util from crate to module in subsystem

The point of making a sub-crate is to ensure that only the necessary
parts of a program get compiled; if a dependent package needed only
subsystem-util, and not subsystem, then subsystem wouldn't need to
be compiled.

However, that will never happen: subsystem-util depends on
subsystem::messages, so subsystem will always be compiled.

Therefore, it makes more sense to add it as a module in the existing
crate than as a new and distinct crate.

* make runtime request sender type generic

* candidate backing subsystem uses util for api requests

* add struct Validator representing the local validator

This struct can be constructed when the local node is a validator;
the constructor fails otherwise. It stores a bit of local data, and
provides some utility methods.

* add alternate constructor for better efficiency

* refactor candidate backing to use utility methods

* fix test breakage caused by reordering tests

* restore test which accidentally got deleted during merge

* start extracting jobs management into helper traits + structs

* use util::{JobHandle, Jobs} in CandidateBackingSubsystem

* implement generic job-manager subsystem impl

This means that the work of implementing a subsystem boils down
to implementing the job, and then writing an appropriate
type definition, i.e.

pub type CandidateBackingSubsystem<Spawner, Context> =
	util::JobManager<Spawner, Context, CandidateBackingJob>;

* add hash-extraction helper to messages

* fix errors caused by improper rebase

* doc improvement

* simplify conversion from overseer communication to job message

* document fn hash for all messages

* rename fn hash() -> fn relay_parent

* gracefully shut down running futures on Conclude

* ensure we're validating with the proper validator index

* rename: handle_unhashed_msg -> handle_orphan_msg

* impl Stream for Jobs<Spawner, Job>

This turns out to be relatively complicated and requires some
unsafe code, so we'll want either detailed review, or to choose
to revert this commit.

* add missing documentation for public items

* use pin-project to eliminate unsafe code from this codebase

* rename SenderMessage -> FromJob

* reenvision the subsystem requests as an extension trait

This works within `util.rs`, but fails in `core/backing/src/lib.rs`,
because we don't actually create the struct soon enough. Continuing
down this path would imply substantial rewriting.

* Revert "reenvision the subsystem requests as an extension trait"

This reverts commit a5639e36017a72656b478caddcaa30e2d4e6112a.

The fact is, the new API is more complicated to no real benefit.

* apply suggested futuresunordered join_all impl

* CandidateValidationMessage variants have no top-level relay parents

* rename handle_orphan_msg -> handle_unanchored_msg

* make most node-core-backing types private

Now the only public types exposed in that module are
CandidateBackingSubsystem and ToJob. While ideally we could reduce
the public interface to only the former type, that doesn't work
because ToJob appears in the public interface of CandidateBackingSubsystem.

This also involves changing the definition of CandidateBackingSubsystem;
it is no longer a typedef, but a struct wrapping the job manager.

* *: Enable authority discovery by default

Instead of having to explicitly enable the authority discovery module on
validator and sentry nodes, this commit enables the module by default.

Today there is no way for non validator or sentry nodes to run the
module. That might change in the future.
