node: allow websocket and HTTP on the same port (ethereum#20810)
This change makes it possible to run geth with JSON-RPC over HTTP and WebSocket on the same TCP port. The default port for WebSocket is still 8546. geth --rpc --rpcport 8545 --ws --wsport 8545 This also removes a lot of deprecated API surface from package rpc. The rpc package is now purely about serving JSON-RPC and no longer provides a way to start an HTTP server.
