kubernetes: pkg/api doesn't compile with latest ugorji/go/codec

$ # with an empty GOPATH
$ go get k8s.io/kubernetes/pkg/api

What I expected to happen: the package is fetched, compiled, and made available for use.

What actually happened:

# k8s.io/kubernetes/pkg/api

type.generated.go needs to be regenerated with the latest codec.

It is insufficient to say this is handled by Godeps, as third-party packages directly import "k8s.io/kumernetes/pkg/api", and you don’t rewrite your import paths.
