All packages, except for `cmd` and `internal`, have been moved into a new `v1` root package. Old packages are kept for backwards-compatibility reasons. All contained code is replaced with simple type aliases and proxy functions to `v1` implementations. Old packages default to the Rego v0 syntax, new `v1` packages default to the Rego v1 syntax.
