Calling _mount doesn't work when we want to add mount options such
as realtime devices. Fix it by calling _scratch_options first then
mount with $SCRATCH_OPTIONS.

By default, _dmerror_load_*_table() suspends the dm device with
"--nolockfs" option. Callers have to feed two arguments to these
functions to change the behavior, with the second being 1, but the
first argument is not used at all, which doesn't make sense.
Fix it by checking if the first argument is "lockfs" and removing
"--nolockfs" option if so, or passing all options to dmsetup.

_dmerror_cleanup()/_cleanup_flakey may fail to remove dm device due to
EBUSY and cause subsequent tests to fail.
Fix it by calling $UDEV_SETTLE_PROG before remove dm device to make sure
no one is using it.

Add functions to the dmerror routine so that we can load both the
error table and the linear table. This will help us with EIO testing
of copy-on-write.

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.

Controlled EIO from the device is achieved using the dm device.
Helper functions are at common/dmerror.
Broadly steps will include calling _dmerror_init().
_dmerror_init() will use SCRATCH_DEV to create dm linear device and assign
DMERROR_DEV to /dev/mapper/error-test.
When test script is ready to get EIO, the test cases can call
_dmerror_load_table() which then it will load the dm error.
so that reading DMERROR_DEV will cause EIO. After the test case is
complete, cleanup must be done by calling _dmerror_cleanup().
