XFS used to retry forever on non-critical errors, and unmount could
hang in such case. Commit e6b3bb78962e ("xfs: add "fail at unmount"
error handling configuration") introduced an error configuration
option in sysfs(fail_at_unmount) and made this behavior
configurable.
Now test this "fail_at_unmount" behavior to make sure XFS doesn't
retry forever on error at unmount time, if configured so. Also
introduced new helpers to require/set/get sysfs attributes.

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.

The test program src/test-nextquota.c relies on atoi() to convert a
string to an *unsigned* int. If the string represents an integer
which is greater than INT_MAX, it is undefined how atoi(3) works,
and it turns out that:
uint id = atoi("2147483649");
results in id == 2147483649 on x86_64, and id == 2147483647 on a
32-bit x86 platform.
So use strtoul(3) instead, which is portable and technically correct

For the replace tests we need a device as a spare device,
here functions _spare_dev_get() and _spare_dev_put()
will get it from the SCRATCH_DEV_POOL_SAVED, which is set
when _scratch_dev_pool_get() is called, and is based on how
many has already been assigned to SCRATCH_DEV_POOL.
usage:
_scratch_dev_pool_get 3
_spare_dev_get
SPARE_DEV will have a device set which can be
used as the replace target device.
_spare_dev_put
_scratch_dev_pool_put
_spare_dev_get() will pick the next device after SCRATCH_DEV_POOL
devices, from the SCRATCH_DEV_POOL_SAVED, and assigns it to
SPARE_DEV. _spare_dev_put() will set to SPARE_DEV to null.

XFS has a bug where directory readahead completions can occur after
unmount. This can lead to a crash or panic because metadata read
verification attempts to access core XFS data structures (e.g., the
log) after they have been freed and certain pointers have been
reset.
Add a test that triggers directory readahead, delays the readahead
I/O and immediately unmounts the filesystem. This test is part of
the dangerous group as it will cause kernels affected by the bug to
crash.
