reflink: test CoW behavior with IO errors

Browse Source 
Test various scenarios (with dm-flakey) where we simulate write
failures during CoW, to see if the FS can get through it without
blowing up or corrupting data.  Plumb in a FS-generic method to
sort out repairing filesystems after they get hit by IO errors.
