mkfs.xfs does not do a very good job of input validation. This test
is designed to exercise the input validation and test good/bad
combinations of options being set. It will not pass on an old
mkfs.xfs binary - it is designed to be the test case for an input
validation cleanup (merged in spring/summer 2016).

CHANGES:
  * Skip this test on older binaries, detected by a few feature checks

Cheers,
Jan

I think this can be put into a new _require rule in common/rc, as Dave
suggested in his previous review:

"
... a "_require_xfs_mkfs_validation" rule should be
written to determine the version of mkfs being. e.g. by testing one
of the failure cases that the unfixed binary says is ok.
"

Thanks,
Eryu

Mmm, I would say that there is a question whether any other test will
ever need it (and its author remember that there is such function),
but all right. You are two now, who says this, so I will go along.

And I think I will put everything into one patchset, because extended
names fixes has to be applied first for _notrun to work correctly,
then the common/rc functions (I'm making two - one for the new and one
for the old behaviour) and at last can come this and the xfs/096 test.
