Perform attestation check before broadcast (#2550)
Currently, we have a bit of a convoluted flow where when sending
attestations, we start broadcasting them over gossip then pass them to
the attestation validation to include them in the local attestation pool
- it should be the other way around: we should be checking attestations
_before_ gossipping them - this serves as an additional safety net to
ensure that we don't publish junk - this becomes more important when
publishing attestations from the API.

Also, the REST API was performing its own validation meaning
attestations coming from REST would be validated twice - finally, the
JSON RPC wasn't pre-validating and would happily broadcast invalid
attestations.

* Unified attestation production pipeline with the same flow for gossip,
locally and API-produced attestations: all are now validated and entered
into the pool, then broadcast/republished
* Refactor subnet handling with specific SubnetId alias, streamlining
where subnets are computed, avoiding the need to pass around the number
of active validators
* Move some of the subnet handling code to eth2_network
* Use BitArray throughout for subnet handling

remove attestation/aggregate queue (#2519)
With the introduction of batching and lazy attestation aggregation, it
no longer makes sense to enqueue attestations between the signature
check and adding them to the attestation pool - this only takes up
valuable CPU without any real benefit.

* add successfully validated attestations to attestion pool directly
* avoid copying participant list around for single-vote attestations,
pass single validator index instead
* release decompressed gossip memory earlier, specially during async
message validation
* use cooked signatures in a few more places to avoid reloads and errors
* remove some Defect-raising versions of signature-loading
* release decompressed data memory before validating message

only deserialize attestation and aggregation gossiped signatures once (#2472)
* only deserialize attestation and aggregation gossiped signatures once

* re-indent some aggregate checks into block scope

* spelling

* remove debugging assertion

* put part of gossip validation back into block context

* attestation pool test signature loading isn't so unsafe, and exportRaw isn't free

* remove more development doAsserts; don't exportRaw in loops

Batch attestations (#2439)
* batch attestations

* Fixes (but now need to investigate the chronos 0 .. 4095 crash similar to https://github.com/status-im/nimbus-eth2/issues/1518

* Try to remove the processing loop to no avail :/

* batch aggregates

* use resultsBuffer size for triggering deadline schedule

* pass attestation pool tests

* Introduce async gossip validators. May fix the 4096 bug (reentrancy issue?) (similar to sync unknown blocks #1518)

* Put logging at debug level, add speed info

* remove unnecessary batch info when it is known to be one

* downgrade some logs to trace level

* better comments [skip ci]

* Address most review comments

* only use ref for async proc

* fix exceptions in eth2_network

* update async exceptions in gossip_validation

* eth2_network 2nd pass

* change to sleepAsync

* Update beacon_chain/gossip_processing/batch_validation.nim

set upper bound on EpochRef cache (#2403)
* set upper bound on EpochRef cache

* max 32 EpochRef instances
* less memory waste in BlockRef by removing EpochRef seq that is mostly
unused (~20mb)
* less memory waste in dag block lookup by not keeping an extra copy of
digest (~70mb)
* fix `==` and `$` for Eth2Digest
* remove `ChainDAG.tmpState` (~50mb?)

all in all, this branch cuts mainnet memory usage by ~160-180mb and puts
limits on EpochRef cache usage - where normally it hovered around 950mb
before, it's now sitting at 600-700mb on my machine.
