>From linux v4.3 and xfsprogs v4.2, xfs_copy support to copy a V5 XFS.
Before that, copy a V5 XFS will cause target fs corruption, and only
use "-d" option can resolve that problem.
For this old reason, xfstests use below patch to add '-d' option to
xfs_copy, make sure xfs_copy always use that option if it try to copy
a V5 XFS:
8346e53 common: append -d option to XFS_COPY_PROG when testing v5 xfs
But xfs_copy full support v5 xfs now. So xfstest miss the coverage of
copy a V5 XFS without '-d'. For test this feature I did below things:
1. Revert commit 8346e53
2. Add a new common function _require_xfs_copy(), if a test try to
use old xfsprogs to copy a V5 xfs, it'll skip that test.
3. Add above common function into all xfs_copy related cases.
4. xfs/073 test V4 xfs forcibly by specify "-m crc=0" in case. I
think it's useless now, so remove it.
There's a xfs_copy related case I didn't add _require_xfs_copy()
to it -- xfs/032, due to it tests "xfs_copy -d" directly.
