* rpc: improve codec abstraction rpc.ServerCodec is an opaque interface. There was only one way to get a codec using existing APIs: rpc.NewJSONCodec. This change exports newCodec (as NewFuncCodec) and NewJSONCodec (as NewCodec). It also makes all codec methods non-public to avoid showing internals in godoc. While here, remove codec options in tests because they are not supported anymore. * p2p/simulations: use github.com/gorilla/websocket This package was the last remaining user of golang.org/x/net/websocket. Migrating to the new library wasn't straightforward because it is no longer possible to treat WebSocket connections as a net.Conn. * vendor: delete golang.org/x/net/websocket * rpc: fix godoc comments and run gofmt
