Fork choice fixes 5 (#1381)
* limit attestations kept in attestation pool

With fork choice updated, the attestation pool only needs to keep track
of attestations that will eventually end up in blocks - we can thus
limit the horizon of attestations that we keep more aggressively.

To get here, we expose getEpochRef which gets metadata about a
particular epochref, and make sure to populate it when a block is added
- this ensures that state rewinds during block addition are minimized.

In addition, we'll use the target root/epoch when validating
attestations - this helps minimize the number of different states that
we need to rewind to, in general.

* remove CandidateChains.justifiedState

unused

* remove BlockPools.Head object

* avoid quadratic quarantine loop

* fix

cache block hash (#1329)
hash_tree_root was turning up when running beacon_node, turns out to be
repeated hash_tree_root invocations - this pr brings them back down to
normal.

this PR caches the root of a block in the SignedBeaconBlock object -
this has the potential downside that even invalid blocks will be hashed
(as part of deserialization) - later, one could imagine delaying this
until checks have passed

there's also some cleanup of the `cat=` logs which were applied randomly
and haphazardly, and to a large degree are duplicated by other
information in the log statements - in particular, topics fulfill the
same role

Restore compilation with custom presets (#1309)
This also assigns precise types to the constants in the minimal

errors when custom presets are used (previously, only the custom
presets have precisely assigned types for the constants).

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
