fix req/resp protocol (#1621)
per spec, we must half-close request stream - not doing so may lead to
failure of the other end to start processing our request leading to
timeouts.

In particular, this fixes many sync problems that have been seen on
medalla.

* remove safeClose - close no longer raises
* use per-chunk timeouts in request processing

Jacek Sieka 22998fdfd4 avoid double deserialization
When blocks and attestations arrive, they are SSZ-decoded twice: once
for validation and once for processing. This branch enqueues the decoded
block directly for processing, avoiding the second, slow
deserialization.

* move processing of blocks and attestations to queue
* ...and out from beacon_node
* split attestation processing into attestations and aggregates
  * also updates metrics
* clean up logging to better follow the lifetime of gossip: arrival,
validation and processing
* drop attestations and aggregates if there are too many
* try to prioritise blocks and aggregates before single-validator
attestations

remove snappy RPC support (#1477)
removed in 0.12.2 - the flow, in particular when the other peer doesn't
support snappy, is hard to follow because of the trial-and-error
approach - removing it simplifies things and removes some of the
hard-to-read parts of the thunking etc

use libp2p peer events to track peer (#1468)
this resolves some peer counting issues that were happening because the
lifetime future in PeerInfo was unreliable (multiple PeerInfo instances
existed per peer)

In addition, this solves another race condition: when connecting to a
peer and later dialling that protocol, it is not certain that the same
connection will be used if there's a concurrent incoming peer connection
ongoing - better not make too many assumptions about who sent statuses
when.

Trusted blocks (#1227)
* cleanups

* fix ncli state root check flag
* add block dump to ncli_db
* limit ncli_db benchmark length
* tone down finalization logs

* introduce trusted blocks

We only store blocks whose signature we've verified in the database - as
such, there's no need to check it again, and most importantly, no need
to deserialize the signature when loading from database.

50x startup time improvement, 200x block load time improvement.

* fix rewinding when deposits have invalid signature
* speed up ancestor iteration by avoiding copy
* avoid deserializing signatures for trusted data
* load blocks lazily when rewinding (less memory used)

* chronicles workarounds

* document trustedbeaconblock
