* async batch verification
When batch verification is done, the main thread is blocked reducing
concurrency.
With this PR, the new thread signalling primitive in chronos is used to
offload the full batch verification process to a separate thread
allowing the main threads to continue async operations while the other
threads verify signatures.
Similar to previous behavior, the number of ongoing batch verifications
is capped to prevent runaway resource usage.
In addition to the asynchronous processing, 3 addition changes help
drive throughput:
* A loop is used for batch accumulation: this prevents a stampede of
small batches in eager mode where both the eager and the scheduled batch
runner would pick batches off the queue, prematurely picking "fresh"
batches off the queue
* An additional small wait is introduced for small batches - this helps
create slightly larger batches which make better used of the increased
concurrency
* Up to 2 batches are scheduled to the threadpool during high pressure,
reducing startup latency for the threads
Together, these changes increase attestation verification throughput
under load up to 30%.
* fixup
* Update submodules
* fix blst build issues (and a PIC warning)
* bump

* speed up state/block loading
When loading blocks and states from db/era, we currently redundantly
check their CRC32 - for a state, this costs 50ms of loading time
presently (110mb uncompressed size) on a decent laptop.
* remove `maxDecompressedDbRecordSize` - not actually used on recent
data since we store the framed format - also, we're in luck: we blew
past the limit quite some time ago
* fix obsolete exception-based error checking
* avoid `zeroMem` when reading from era store
see https://github.com/status-im/nim-snappy/pull/22 for benchmarks
* bump snappy
* Add new REST endpoints to monitor REST server connections and new chronos metrics.
* Bump head versions of chronos and presto.
* Bump chronos with regression fix.
* Remove outdated tests which was supposed to test pipeline mode.
* Disable pipeline mode in resttest.
* Update copyright year.
* Upgrade test_signing_node to start use AsyncProcess instead of std library's osproc.
Bump chronos to check graceful shutdown.
* Update AllTests.
* Bump chronos.
