Btrfs devel - Jan 2014 - [PATCH RESEND] xfstests: btrfs/029: moving and deleting sparse copies on btrfs

Moving and deleting cloned ("reflinked") files on btrfs:
   - Create a file and a reflink
   - Move both to a directory
   - Delete the original (moved) file, check that the copy still exists.

[sandeen: mostly cosmetic changes]
