* babe: don't repeatedly lookup keys in authorship rpc function

Expose a new function `claim_slot_using_keypars` in Babe so that the `babe_epochAuthorship` can
lookup authorship for all slots in the epoch without repeatedly looking up keys in the keystore.

Time to run the `babe_epochAuthorship` RPC call goes from 7s to 25ms on a local dev chain on my
machine.

* babe: pass reference to slice instead of ref to Vec

* babe: fix bunch of clippy warnings

* fix this damn wrong staking test.

* Update frame/staking/src/tests.rs

* Make `Digest` support `StorageAppend`

This adds support for `StorageAppend` to `Digest`. Digest is just a
wrapper around a `Vec` and we abuse the fact that SCALE does not puts
any special marker into the encoding for structs. So, we can just append
to the encoded Digest. A test is added that ensures, if the `Digest`
format ever changes, we remove this optimization.

* Improve error message when essential task failed

* client/network-gossip/bridge: Use bounded channel

Instead of returning an unbounded channel on
`GossipEngine::messages_for` return a bounded channel. For now the
channel length is determined by the amount of past messages cached in
the `ConsensusGossip`.

With a bounded channel, one can't just fire-and-forget style send into
it, but has to first check whether the channel is ready. Thus this
commit restructures `GossipEngine::poll` and introduces a
`ForwardingState` into `GossipEngine`.

* really rough mock runtime

* client: Replace `unsafe_rpc_expose` with an `RpcMethods` enum

which can be either Default, Safe or Unsafe. The idea is to have the
following:
|                       | --rpc-external=false  | --rpc-external=true   |
|---------------------  |-------------------    |-----------------      |
| --rpc-methods=Default |                       | unsafe calls denied   |
| --rpc-methods=Safe    | unsafe calls denied   | unsafe calls denied   |
| --rpc-methods=Unsafe  |                       |                       |
Since the previous `unsafe-rpc-expose` option was confusing.

* client: Only warn against exposing externally unsafe RPC method set

* Apply suggestions from code review

* cli: Rephrase doc comment for rpc_methods config

* Improve debuggability of build_spec_works

...by printing to stderr the stderr of the command. This is normally
suppressed for succesful tests but not for failing ones - if that's the
case then it's useful to see the test failure reason inline rather than
having to execute the command separately ourselves.

* Rename RpcMethods::{Default => Auto} variant

* Update bin/node/cli/tests/build_spec_works.rs

Previously, when publishing ones address onto the DHT, the signature
signing those addresses would be SCALE encoded twice.

This commit removes the second encoding and adjusts the tests
to catch future regressions.
