* core/types, core/vm, eth, tests: regenerate gencodec files * Makefile: update devtools target Install protoc-gen-go and print reminders about npm, solc and protoc. Also switch to github.com/kevinburke/go-bindata because it's more maintained. * contracts/ens: update contracts and regenerate with solidity v0.4.19 The newer upstream version of the FIFSRegistrar contract doesn't set the resolver anymore. The resolver is now deployed separately. * contracts/release: regenerate with solidity v0.4.19 * contracts/chequebook: fix fallback and regenerate with solidity v0.4.19 The contract didn't have a fallback function, payments would be rejected when compiled with newer solidity. References to 'mortal' and 'owned' use the local file system so we can compile without network access. * p2p/discv5: regenerate with recent stringer * cmd/faucet: regenerate * dashboard: regenerate * eth/tracers: regenerate * internal/jsre/deps: regenerate * dashboard: avoid sed -i because it's not portable * accounts/usbwallet/internal/trezor: fix go generate warnings
