This adds an implementation of node discovery via DNS TXT records to the go-ethereum library. The implementation doesn't match EIP-1459 exactly, the main difference being that this implementation uses separate merkle trees for tree links and ENRs. The EIP will be updated to match p2p/dnsdisc. To maintain DNS trees, cmd/devp2p provides a frontend for the p2p/dnsdisc library. The new 'dns' subcommands can be used to create, sign and deploy DNS discovery trees.
