all: core rework for the merge transition (#23761) * all: work for eth1/2 transtition * consensus/beacon, eth: change beacon difficulty to 0 * eth: updates * all: add terminalBlockDifficulty config, fix rebasing issues * eth: implemented merge interop spec * internal/ethapi: update to v1.0.0.alpha.2 This commit updates the code to the new spec, moving payloadId into it's own object. It also fixes an issue with finalizing an empty blockhash. It also properly sets the basefee * all: sync polishes, other fixes + refactors * core, eth: correct semantics for LeavePoW, EnterPoS * core: fixed rebasing artifacts * core: light: performance improvements * core: use keyed field (f) * core: eth: fix compilation issues + tests * eth/catalyst: dbetter error codes * all: move Merger to consensus/, remove reliance on it in bc * all: renamed EnterPoS and LeavePoW to ReachTDD and FinalizePoS * core: make mergelogs a function * core: use InsertChain instead of InsertBlock * les: drop merger from lightchain object * consensus: add merger * core: recoverAncestors in catalyst mode * core: fix nitpick * all: removed merger from beacon, use TTD, nitpicks * consensus: eth: add docstring, removed unnecessary code duplication * consensus/beacon: better comment * all: easy to fix nitpicks by karalabe * consensus/beacon: verify known headers to be sure * core: comments * core: eth: don't drop peers who advertise blocks, nitpicks * core: never add beacon blocks to the future queue * core: fixed nitpicks * consensus/beacon: simplify IsTTDReached check * consensus/beacon: correct IsTTDReached check Co-authored-by: rjl493456442 <garyrong0905@gmail.com> Co-authored-by: Péter Szilágyi <peterke@gmail.com>

cmd/geth: add --config file flag (#13875) * p2p/discover, p2p/discv5: add marshaling methods to Node * p2p/netutil: make Netlist decodable from TOML * common/math: encode nil HexOrDecimal256 as 0x0 * cmd/geth: add --config file flag * cmd/geth: add missing license header * eth: prettify Config again, fix tests * eth: use gasprice.Config instead of duplicating its fields * eth/gasprice: hide nil default from dumpconfig output * cmd/geth: hide genesis block in dumpconfig output * node: make tests compile * console: fix tests * cmd/geth: make TOML keys look exactly like Go struct fields * p2p: use discovery by default This makes the zero Config slightly more useful. It also fixes package node tests because Node detects reuse of the datadir through the NodeDatabase. * cmd/geth: make ethstats URL settable through config file * cmd/faucet: fix configuration * cmd/geth: dedup attach tests * eth: add comment for DefaultConfig * eth: pass downloader.SyncMode in Config This removes the FastSync, LightSync flags in favour of a more general SyncMode flag. * cmd/utils: remove jitvm flags * cmd/utils: make mutually exclusive flag error prettier It now reads: Fatal: flags --dev, --testnet can't be used at the same time * p2p: fix typo * node: add DefaultConfig, use it for geth * mobile: add missing NoDiscovery option * cmd/utils: drop MakeNode This exposed a couple of places that needed to be updated to use node.DefaultConfig. * node: fix typo * eth: make fast sync the default mode * cmd/utils: remove IPCApiFlag (unused) * node: remove default IPC path Set it in the frontends instead. * cmd/geth: add --syncmode * cmd/utils: make --ipcdisable and --ipcpath mutually exclusive * cmd/utils: don't enable WS, HTTP when setting addr * cmd/utils: fix --identity
