Johan Fylling a179a24c48 v1 API
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.
