a2790af67a pkg/eval: Clean up the structure and methods of Evaler and Frame.
- Make Evaler mostly thread-safe. The only remaining thread-unsafe part is the
  modules field, which is more tricky than other fields.

- Remove the state and evalerScopes type, and move their fields into Evaler.

- Expose valuePrefix via a get method, and change PortsFromFiles to take the
  prefix instead of a *Evaler. Also expose a PortsFromStdFiles.

- Make Evaler a normal field of Frame, instead of an embedded field. This makes
  access to global states more explicit.
