This is obviously wrong and makes ./check -r skip over tests on ext4
with "ext4 on $DEV not configured with metadata journaling".

The check script requires that it be run as root, so adding
individualized checks for this in each teat is not needed.

To avoid having many tests repeating the following pattern:
_load_flakey_table $FLAKEY_DROP_WRITES
_unmount_flakey
_load_flakey_table $FLAKEY_ALLOW_WRITES
_mount_flakey
add the helper function _flakey_drop_and_remount to remove
the existing duplicated code and serve as a shortcut.

generic/085 was failing on a machine w/o devicemapper kernel
support because it requires the linear target, but didn't
explicitly test for it.
I could have cut & pasted _require_dm_linear(), but chose
to go the route of a generic helper, _require_dm_target $FOO,
because some day someone will need the zero target, the error
target, or who knows.
Add the helper, use it in test generic/085, and convert
_require_dm_flakey, _require_dm_snapshot, and
_dmerror_required with this new helper.

Many tests use dm_flakey to trigger log replay, but for filesystems that
don't support metadata journaling, this causes failures when it shouldn't.
(i.e. we can hardly test log replay if there is no log, and the subsequent
filesystem check will turn up errors).
For some tests they actually sync everything we care about, and find
inconsistencies elsewhere, but I erred on the side of simply not running
the test in most cases.

This test is motivated by an fsync issue discovered in btrfs.
The issue in btrfs was that adding a new hard link to an inode that
already had a large number of hardlinks and fsync the inode, would
make the fsync log replay code update the inode with a wrong link count
(smaller than the correct value). This resulted later in dangling
directory index entries, after removing most of the hard links
(correct_value - wrong_value), that were visible to user space but it
was impossible to delete them or do any other operation on them (since
they pointed to an inode that didn't exist anymore, resulting in -ESTALE
errors).
The btrfs issue was fixed by the following linux kernel patch:
Btrfs: fix fsync when extend references are added to an inode
This issue was present in btrfs since the extrefs (extend references)
feature was added (2012).
