performance fixes (#2259)
* performance fixes

* don't mark tree cache as dirty on read-only List accesses
* store only blob in memory for keys and signatures, parse blob lazily
* compare public keys by blob instead of parsing / converting to raw
* compare Eth2Digest using non-constant-time comparison
* avoid some unnecessary validator copying

This branch will in particular speed up deposit processing which has
been slowing down block replay.

Fix the corrupted database state on Pyrmont nodes; Add mainnet genesis (#2056)
* Handle some web3 timeouts better

* Add support for developer .env files

* Eth1 improvements; Mainnet genesis state

Notable changes:

* The deposits table have been removed from the database. The client
  will no longer process all deposits on start-up.

* The network metadata now includes a "state snapshot" of the deposit
  contract. This allows the client to skip syncing deposits made prior
  to the snapshot (i.e. genesis). Suitable metadata added for Pyrmont
  and Mainnet.

* The Eth1 monitor won't be started unless there are validators attached
  to the node.

* The genesis detection code is now optional and disabled by default

* Bugfix: The client should not produce blocks that will fail validation
  when it hasn't downloaded the latest deposits yet

* Bugfix: Work around the database corruption affecting Pyrmont nodes

* Remove metadata for Toledo and Medalla

Jacek Sieka fc7885b27e Store block summary in database
This introcudes a cache for block summaries, useful for instantiating
the block dag on startup, bringing medalla startup times down from
minutes to seconds.

This is something of a temporary band-aid that would be obsoleted by a
finalized block store.

fix db growth on attestation processing (#1860)
It turns out that we often save lots of states in the database that are
the result of empty slot processing only - here, we make sure to only
save a state if a block follows - this fixes several issues:

* empty slot states are not always pruned leading to state database size
explosion
* storing states is (very) slow which slows down processing in general,
so we should only do it when it's likely to be useful
* attestation processing doesn't get stuck on saving random states that
won't appear in the chain history
