* grandpa: use AuthoritySetChanges to generate warp sync proof

* node: init grandpa warp sync protocol

* grandpa: iterator for AuthoritySetChanges

* grandpa: rewrite warp sync proof generation

* grandpa: remove old code for warp sync generation

* grandpa: fix indentation

* grandpa: fix off by one

* grandpa: use binary search to find start idx when generating warp sync proof

* grandpa: add method to verify warp sync proofs

* grandpa: remove unnecessary code to skip authority set changes

* grandpa: add test for warp sync proof generation and verification

* grandpa: add missing docs

* grandpa: remove trailing comma

* Ahh

* Work work work

* Fix all the compilation errors

* Fix test

* More fixes...

* Made a start

* So the proof between authority set is phragmen one, this is crazy big,
or is there some signing of the result : that is the storage key, damn?

* ok getting from header digest seems doable.

* for testing

* get set id from storage directly (should use runtime to handler change).

* move test to init

* correct auth key

* fix iteration

* Correct proof content

* actually update block number.

* actually check last justif against its header

* justification relation to new authorities through header hash check is
needed here. This assumes the hash from header is calculated.

* Few changes

* Connected up cheme's branch

* Clean up

* Move things around a bit so that adding the grandpa warp sync request response protocol happens in the node code

* Nits

* Changes to comments

* Cheme changes

* Remove todos and test compile.

* Rename _authority_ related proof function to _warp_sync_ .

* Update client/grandpa-warp-sync/src/lib.rs

quick fix

* Put the warp sync request response protocol behind a feature flag because we dont' need it on a light client.

* Update client/grandpa-warp-sync/src/lib.rs

Quick fix

* Update Cargo.lock

* Adding test, comment on limitation related to 'delay', this could
be implemented but with a cost.

* Set between a delay override last fragment.

* Check for pending authority set change at start.

* adjust index

* custom cache is not a good idea.

* Use a simple cache instead.

* restore broken indentation

* Address crate rename

* Merge conflict badly resolved, sorry

* Happy new year

Updates the copyright years and fixes wrong license headers.

* Fix the template

* Split HEADER into HEADER-APACHE & HEADER-GPL

* client: cleanup redundant semicolon warnings

* grandpa: remove usage of deprecated compare_and_swap

* grandpa: remove light-client specific block import

* consensus, network: remove finality proofs

* grandpa: use bytes type for justification rpc notification

* grandpa: always create justification if there are rpc subscribers

* grandpa: wording

* grandpa: replace notify_justification macro with function

* grandpa: prefer Option<&T> over &Option<T>

* grandpa: change some logging from trace to debug

* grandpa: cleanup unused import

* Rough skeleton for what I think the RPC should look like

* Create channel for sending justifications

Sends finalized header and justification from Grandpa to the
client. This lays the groundwork for hooking into the RPC module.

* WIP: Add subscribers for justifications to Grandpa

Adds the Sender end of a channel into Grandpa, through which notifications
about block finality events can be sent.

* WIP: Add a struct for managing subscriptions

Slightly different approach from the last commit, but same
basic idea. Still a rough sketch, very much doesn't compile yet.

* Make naming more clear and lock data in Arc

* Rough idea of what RPC would look like

* Remove code from previous approach

* Missed some things

* Update client/rpc-api/src/chain/mod.rs

This PR refactors the metrics measuring and Prometheus exposing entity in sc-service into its own submodule and extends the parameters it exposes by:

- system load average (over one, five and 15min)
- the TCP connection state of the process (lsof), refs #5304
- number of tokio threads
- number of known forks
- counter for items in each unbounded queue (with internal unbounded channels)
- number of file descriptors opened by this process (*nix only at this point)
- number of system threads (*nix only at this point)
