btrfs migration

What I want to do is to "migrate" a btrfs sytstem from one host to
another, and back.

By itself, btrfs only allows very simple incremental send/receive by
recording the remote parent's uid.

Maybe best to not mess with this.
Use snapshots for restore points and incremental backups from fixed source.

Use rsync for migration and restore.
