Dual headed fork choice [Revolution] (#1238) 
* Dual headed fork choice

* fix finalizedEpoch not moving

* reduce fork choice verbosity

* Add failing tests due to pruning

* Properly handle duplicate blocks in sync

* test_block_pool also add a test for duplicate blocks

* comments addressing review

* Fix fork choice v2, was missing integrating block proposed

* remove a spurious debug writeStackTrace

* update block_sim

* Use OrderedTable to ensure that we always load parents before children in fork choice

* Load the DAG data in fork choice at init if there is some (can sync witti)

* Cluster of quarantined blocks were not properly added to the fork choice

* Workaround async gcsafe warnings

* Update blockpoool tests

* Do the callback before clearing the quarantine

* Revert OrderedTable, implement topological sort of DAG, allow forkChoice to be initialized from arbitrary finalized heads

* Make it work with latest devel - Altona readyness

* Add a recovery mechanism when forkchoice desyncs with blockpool

* add the current problematic node to the stack

* Fix rebase indentation bug (but still producing invalid block)

* Fix cache at epoch boundaries and lateBlock addition

add tests for unviable blocks (#1271) 
* add tests for unviable blocks

also enable finalization tests in all test configs - they're plenty fast
now
also fix newClone for non-rvo cases. sigh.

Small fixes (#1165) 
* random fixes

* create dump dir on startup
* don't crash on failure to write dump
* fix a few `uint64` instances being used when indexing arrays - this
should be a compile error but isn't due to compiler bugs
* fix standalone test_block_pool compilation
* add signed block processing in ncli

* reuse cache entry instead of allocating a new one

* allow for small clock disparities when validating blocks
