Feature/goerli replay clique poa (#743) * extract unused clique/mining support into separate file why: mining is currently unsupported by nimbus * Replay first 51840 transactions from Goerli block chain why: Currently Goerli is loaded but the block headers are not verified. Replaying allows real data PoA development. details: Simple stupid gzipped dump/undump layer for debugging based on the zlib module (no nim-faststream support.) This is a replay running against p2p/chain.persistBlocks() where the data were captured from. * prepare stubs for PoA engine * split executor source into sup-modules why: make room for updates, clique integration should go into executor/update_poastate.nim * Simplify p2p/executor.processBlock() function prototype why: vmState argument always wraps basicChainDB * split processBlock() into sub-functions why: isolate the part where it will support clique/poa * provided additional processTransaction() function prototype without _fork_ argument why: with the exception of some tests, the _fork_ argument is always derived from the other prototype argument _vmState_ details: similar situation with makeReceipt() * provide new processBlock() version explicitly supporting PoA details: The new processBlock() version supporting PoA is the general one also supporting non-PoA networks, it needs an additional _Clique_ descriptor function argument for PoA state (if any.) The old processBlock() function without the _Clique_ descriptor argument retorns an error on PoA networgs (e.g. Goerli.) * re-implemented Clique descriptor as _ref object_ why: gives more flexibility when moving around the descriptor object details: also cleaned up a bit the clique sources * comments for clarifying handling of Clique/PoA state descriptor
