* move old implementers' guide, add skeleton of new

* Split the old implementers' guide into the new one's sections

This is mostly a straightforward copying operation, moving the
appropriate sections from the old guide to the new. However, there
are certain differences between the old text and the new:

- removed horizontal rules between the sections
- promoted headers appropriately within each section
- deleted certain sections which were in the old guide's ToC but
  which were not actually present in the old guide.
- added Peer Set Manager to the new ToC

* remove description headers

It is redundant and unnecessary. Descriptions fall directly under the
top-level header for any given section.

* add stub description of the backing module

* add stub description for the availability module

* add stub description for collators

* add stub description for validity

* add stub description for utility

* highlight TODO and REVIEW comments

* add guide readme describing how to use mdbook

* fix markdownlint lints

* re-title parachains overview

* internal linking for types

* module and subsystem internal links

* .gitignore should have a trailing newline

* node does not have modules, just subsystems

* Add the ability to change the informant's prefix

* Update Cargo.lock

* Update Cargo.lock

* fixed tests

* Rename prefix to informant prefix

* expand subsystems descriptions independent of subsystems overview

The subsystems overview in https://github.com/paritytech/polkadot/pull/1161


is a very useful reference for what subsystems need to talk to each other,
when, and why; it helps us design the actual messages.

However, administratively, it belongs in a different PR. This commit
brings in all the changes made there so far as a base for an independent
PR.

* Reorder subsystem descriptions, add some messages

Update ordering of subsystem descriptions to rough order of use,
mirroring the order in the overview document.

Added some message types. Added OverseerSignal variants to several
types, such that each subsystem only needs to listen for a single
type.

* add some more message types, Statement Distribution overview

* add more detail on Statement Distribution, Misbehavior Arbitration

* intentionally punt MA details for a future PR

* reduce duplication from overseer signal handling

* reword for clarity

* clarify: other modules and subsystems also get to talk to the network

* finish current work on candidate selection

* update candidate backing subsystem description according to current thought

* update mechanism for candidate backing to report collator misbehavior to candidate selection

* sketch out the peer receipt state machine

* Fix typo in roadmap/implementors-guide/guide.md

* Don't specify 'peer validators', as messages from non-validator peers are ignored regardless

* clarify instancing of peer receipt state machine

* add section on peer knowledge tracking

* fix typo in roadmap/implementors-guide/guide.md
