Regression test for read corruption of compressed and shared extents
after punching holes into a file. The same extent is shared by the
same file in consecutive ranges (without other extents in between).
This is motivated by a bug recently found in btrfs for which there
is a patch for the linux kernel titled:
"Btrfs: fix corruption reading shared and compressed extents after hole
punching"
