xfs: regression tests for reflink quota bugs

Browse Source 
Add three tests to look for quota bugs in xfs reflink. The first
test looks for problems when we have speculative cow reservations in
memory, we chown the file, but the reservations don't move to the
new owner.  The second test checks that we remembered to dqattach
the inodes before performing reflink operations. The third is a
stress test for reflink quota handling near enospc and helped us to
find a directio cow write corruption bug when free space is
fragmented.
