synced up to go-ethereum 1.5.0-unstable develop branch major features: * api overhaul due to rpc v2 and node service stack interface changes * blockchain/ethereum contract interaction rewritten using abi/abigen (chequebook, ens) * swarm - cluster control CLI - migration and revamp of prehistoric eth-utils repo * poor man's end to end testing: scripted scenarios in swarm/test using swarm CLI * http proxy now handles 3 url schemes for 1) ens-enabled [bzz], 2) immutable [bzzi] and 3) raw manifest [bzzr] resolution * fixes issues with remote address setting, forwarding and syncing * new control flags to switch swap and sync on and off * placeholder basic implementation Ethereum Name Service * improved logging - now debug level is coherent regression: * uri based versioning support is dropped temporarily since state tree pruning does not guarantee historical record * registrar related functionality temporarily restricted - current ENS provides basic free and unrestricted Register/Resolve accounts/abi: * bind: repeated attempt deployment of contracts, validation against known code, transactor creation from private keys * accountmanager: getUnlocked snatch private key when unlocked cmd: * unlockAccount moved to utils/cmd and exported * getPassPhrase moved to utils/input and exported * accountcmds: reflect the change * js: GlobalRegistrar is dropped (ens) flags: * chequebook, bzzaccount, bzzport, bzzconfig, bzznoswap, bzznosync chequebook: * move from common/ to swarm/services * abigen-ised * specifies its own API (removed chequebook api from swarm/api) kademlia: * move from common to swarm/network/kademlia * address abstracted out to separate file + tests dns/ens/registrar: * moved from swarm/api to swarm/services/ens * implementation is basic placeholder before ENS is implemented * temporary rpc api via ens namespace * the old common/registrar is removed (also from eth/backend apis) swap: * the abstract swap module moved from common to swarm/services * now embedded in the swarm and chequebook specific setup (this will change) * safer chequebook deployment using abigen helpers * backend not field of swap params eth: * public accessor for GPO, needed to construct a PublicBlockChainAPI * extends ContractBackend in eth/bind.go with BalanceAt, GetTxReceipt and CodeAt API calls internal/web3ext * add js bindings for bzz, chequebook rpc apis swarm/api: * refactored api into smaller modules filesystem/storage/testapi * ethereum backend (needed for dns, swap, etc) moved to abi/bind * TODO: further refactor due to #2040 * swarm/api/http: now supports the 3 uri schemes * examples/album updated swarm/cmd: * migrate old eth-utils and modify into a cluster control CLI * bzzup now allows non-local gateway, endpoint specified as second argument swarm/network: * forwarder improved log messages, fixup condition on whether syncer is nil * hive extended with controls for testing support block read/write, swap/sync enabled/disabled * hive keepAlive launches with alarm in case no discover and no kaddb * fix IP address formatting issue [::1] -> became ::1 which refused to dial, now use discover.NewNode#String * integrate functionality for enabling/disabling sync and swap * allow nil sync state - improve syncer interface in protocol * fix SData slice out of bounds bug swarm/test * poor man's testing framework. scripts invoking swarm/cmd/swarm * added tests for basic scenarios connections, swap, sync swarm: * rewrite api using rpc v2 * blockchain comms via abi/abigen + eth.ContractBackend * integrate new flags
