Before xfsprogs commit a872b62 (xfs_copy: band-aids for CRC
filesystems), xfs_copy requires the "-d" option to copy a V5 XFS,
because it can't rewrite the UUID of V5 XFS properly.
Now xfs_copy already full support to copy a V5 XFS. But for above
old problem, xfstests use below patch to make sure xfs_copy always
use "-d" option to copy a V5 XFS:
8346e53 common: append -d option to XFS_COPY_PROG when testing v5 xfs
That cause xfstests miss the coverage of copying a V5 XFS without
"-d". For test this feature I did below things:
1. Changed init_rc(), add "-d" to $XFS_COPY_PROG if xfs_copy can't
copy a V5 XFS properly.
2. xfs/073 test V4 xfs forcibly by specify "-m crc=0" in case. I
think it's useless now, so remove it.
3. Changed xfs/032. If xfs_copy full support to copy a V5 XFS, test
with and without "-d" option, or only test with "-d" option.

Hi,
V2:
1. remove require_xfs_copy() function
2. change the code logic of init_rc function about how to add "-d" to
$XFS_COPY_PROG
3. remove xfs_copy "-d" option of xfs/032
V3:
add comments to explain the change in init_rc()
V4:
Due to xfs/032 test "xfs_copy -d" by default, I don't want to
change the original test coverage. So if xfs_copy full support to
copy a V5 XFS, then test with and without "-d" option twice.
V5:
Pick up "xfs_copy and xfs_repair" part into a function named do_copy.
Thanks,
Zorro
