Test that an incremental send operation correctly issues clone operations
for a file that had different parts of one of its extents cloned into
itself, at different offsets, and a large part of that extent was
overwritten, so all the reflinks only point to subranges of the extent.
This currently fails on btrfs but is fixed by a patch for the kernel that
has the following subject:
"btrfs: send, fix invalid clone operations when cloning from the same file and root"
