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
