From: Darrick J. Wong <djwong@kernel.org>
Parent pointers change the xattr structure dramatically, so fix this
test to handle them. For the most part we can get away with filtering
out the parent pointer fields (which xfs_db decodes for us), but the
namelen/valuelen/attr_filter fields still show through.

These tests depend heavily on the xattr formats created for new files.
Parent pointers break those assumptions, so force parent pointers off.

From: Darrick J. Wong <djwong@kernel.org>
The parent pointers feature isn't supported on tiny 20MB filesystems
because the larger directory transactions result in larger minimum log
sizes, particularly with nrext64 enabled:
** mkfs failed with extra mkfs options added to " -m rmapbt=0, -i nrext64=1, -n parent=1," by test 306 **
** attempting to mkfs using only test 306 options: -d size=20m -n size=64k **
max log size 5108 smaller than min log size 5310, filesystem is too small
We don't support 20M filesystems anymore, so bump the filesystem size up
to 100M and skip this test if we can't actually format the filesystem.
Convert the open-coded punch-alternating logic into a call to that
program to reduce execve overhead, which more than makes up having to
write 5x as much data to fragment the free space.
