* Fix state mismatch in behaviour.rs

* Add TODO

Instead of resetting `SIGPIPE` to the system default handler, we now
handle a clap error manually and ignore any error when writing to
`stdout`/`stderr`. In this way, the node does not silently stops when it
encounters a `SIGPIPE` in normal mode and we still support piping of the
cli output.

* Add logging

Instead of informing the telemetry about each block that is finalized,
we only need to send the last finalized block. This removes log spam on
initial sync.

Substrate was previously running both a chain specific Kademlia DHT as
well as the `/ipfs/kad/1.0.0` Kademlia DHT for backwards compatibility.
(See 710722f0 for details.)

With the end of the transition period this commit removes the former
only leaving the latter and thus preventing the discovery of
incompatible nodes via Kademlia.

* Spawn the network worker with spawn_blocking

* Some comment adjustments

* Fix shutdown not working

* babe: fix formatting

* babe: re-use same epoch data in epoch_authorship rpc method

An `UntilImported` stream wraps a `Stream` of incoming messages and
waits for blocks those messages are based on before passing the messages
on.

The above `Stream` of incoming messages implements `Unpin`, thus there
is no need to use `pin_project` on the `UntilImported` struct. Instead
one only has to add the `Unpin` trait bound on the `I` trait parameter.

* Allow passing multiple --log CLI options

* Comment typo

* Small fix to block response completion reporting

* while -> if

* 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.

* 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.
