Martin Atkins f40800b3a4 Move states/ to internal/states/
This is part of a general effort to move all of Terraform's non-library
package surface under internal in order to reinforce that these are for
internal use within Terraform only.

If you were previously importing packages under this prefix into an
external codebase, you could pin to an earlier release tag as an interim
solution until you've make a plan to achieve the same functionality some
other way.

// stateV2 is a representation of the legacy JSON state format version 3.
//
// It is only used to read version 3 JSON files prior to upgrading them to
// the current format.
//
// The differences between version 2 and version 3 are only in the data and
// not in the structure, so stateV3 actually shares the same structs as
// stateV2. Type stateV3 represents that the data within is formatted as
// expected by the V3 format, rather than the V2 format.
