We already have an interface for "freflink()" called splice().  Splice
has all the arguments needed to implement refcounted data copies and
more.

Yes, splice's name implies more of a "piecing data together" type of
operation, but we can look at reflink() or copyfile() as just "splice
one big piece from here to there".

Thanks,
