Filipe Manana 8a861b8faf btrfs: add test for incremental send for file with shared extents
Test that an incremental send operation works correctly when a file has
shared extents with itself in the send snapshot, with a hole between them,
and the file size has increased in the send snapshot.

This currently fails in 5.5-rc kernels (regression) but is fixed by a
patch that has the following subject:

  Btrfs: send, fix emission of invalid clone operations within the same file
