Andrew Cooper 86cf92f505 libxc/migration: Rationalise the 'checkpointed' field to 'stream_type'
Originally, 'checkpointed' was a boolean signalling the difference between a
plain and a Remus stream.  COLO was added later, but several bits of code
retained boolean-style logic.  While correct, it is confusing to follow.

Additionally, XC_MIG_STREAM_NONE means "no checkpoints" but reads as "no
stream".

Consolidate all the logic on the term 'stream_type', and rename STREAM_NONE
to STREAM_PLAIN.  Re-position the stream_type variable so it isn't
duplicated in both the save and restore unions.

No functional change.
